While the differences in color reproduction between high resolu­ tion scans and lower resolution scans are subtle, they can be quantified and illustrated graphically using the histogram feature of Adobe Photoshop (an image processing software package).

he digital revolution has unleashed a barrage of journal articles that INTRODUCTION T have dealt with many of the technical aspects of digitizing paper­ based images and text. For instance, in a major study, Cornell University, Xerox Corporation and the Commission on Preservation and Access (CPA) undertook a collaborative effort to test a prototype system for recording the text of deteriorating books as digital images (Cloonan 1993, Cohen 1993). Among other things, the study concluded that 600 dots per inch (dpi) scanning and printing results in a high quality paper replace­ ment for brittle textual materials (CPA 1992). Yale University has also undertaken a study to digitize fragile materi­ The digital revolu tion has als. This project is being carried out in three phases. The goals of the unleashed a barrage of journal second phase are to assemble, test, and evaluate the basic operating elements of architecture (Conway and Weaver 1994). As a result articles that have dealt with of this research, it was determined that the optimal scanning resolution for many of the technical aspects of capturing full legibility of microfilm and is 600 dpi (Conway digitizing paper-based images and Weaver 1994). and text. The Bodleian Library at Oxford University is currently working on two separate projects to scan photographs. Gartner (1994) briefly describes the process of digitization and the impact of scanning resolution on text legibility. In another article, Kenney and Conway (1994) discuss four issues related to digitization: 1) system functionality, 2) storage media deterioration, 3) digital image data quality, and 4) integrity of sources. Their treatment of scanning resolution is in terms of black and whi te text, that is, the ability of the scanner to capture the fineness of detail and the legibility of print. Furthermore, Cohen (1993) also touches upon scanning resolution as it relates to the legibility of text. Tilton (1994), on the other hand, discusses scanning resolution in terms of the display size of the digital image. That is, he comments upon the relationship between screen resolution and magnification ratio in order to determine the proper scanning resolution for a digital image. Cartolano, Gertz and Klimley (1995) determined that full legibility of 1 mm text can be achieved if the original image is scanned at 200 dpi in 24 bit color. They stated that "once the full information is captured at the 4 cartogmplzic perspectives Number 23, Winter 1996

highest resolution required for full capture, it should not be necessary to re-scan in the future, since no information would be added by scanning at a higher resolution" (Cartolano et al. 1995, 11 ). It is this sentiment, which is implicit in all the articles mentioned so far, that is challenged in this paper. That is, information that is vital to the integrity of the digital image will be added if the image is scanned at a higher resolution. That information manifests itself in the form of better color reproduction, which is of critical importance if the image is meant to be an access copy of an archival document. While the differences in color While a review of eight articles could hardly be ca ll ed a complete reproduction between high examination of the relevant literature, two related trends do appear. First, resolution scans and lower one of the best documented facts in these and similar articles is that resolution scans are subtle, they increased scanning resolution results in greater legibility of the text and fine details of the digital image. This is not in dispute here. However, the can be quantified and second trend that emerges from these articles is that the discussion of illustrated graphically ... color reproduction tends to focus on issues of bit depth (for example, Cartolano et al. 1995) and palette shifts (for example, Tilton 1994). Little has been written about the fact that increasing the scanning resolution also results in better color reproduction. While the differences in color repro­ duction between high resolution scans and lower resolution scans are subtle, they can be quantified and illustrated graphically using the histo­ gram feature of Adobe Photoshop, an image processing software package for the Macintosh. After a brief review of the principles of scanning, several images scanned at increasing resolutions, along with their histo­ grams, will be presented in this paper to support the author's thesis. 1

SCANNING RESOLUTION AND The type of scanning discussed here produces output in raster format. COLOR REPRODUCTION That is, the information is displayed as an array of square cells, or pixels, each representing a corresponding piece of the original document (Pazner et al. 1992). When the original document is scanned, the scanner "sees" it as an ordered formation of pixels, each having a color or shade of gray, each of which reflect different amounts of light. The scanner then assigns a number to represent the reflectance of each pixel. This matrix of num­ bers becomes the digital image file. This explanation of the process of scanning, while exceedingly brief, outlines the most important variable of concern to this paper, that is, the assignment of a single number to represent the reflectance value for the entire area of a square pixel, the size of which depends upon the pre­ selected scanning resolution. Herein lies the basic problem. For example, a scanning resolution of one dpi would result in a digital image that has one pixel per square inch of the original document. All the colors present within the area represented by that pixel would be combined and a single number would be assigned that represents the average reflectance value for that pixel. ln other words, all the discrete colors that are present within that area on the original would be blended to create a single color for the digitized image. If, however, the scanning resolution were in­ creased, meaning that pixel size is decreased, then more colors could be portrayed within that same one square inch area because more pixels would be required to depict the same size area at the greater resolution; each pixel would be assigned its own separate color value that repre­ sented the reflectance of that smaller pixel area on the original document.

1. All the images used ln this paper were scanned using the default settings for brightness, contrast and threshold. No extra image processing was done. In this way, the author hopes to ensure that comparison between the images will not be influenced by any data manipula­ tion technique. Number 23, Winter 1996 cartographic perspt•ctives 5

This principle is illustrated in Figure 1. The large empty boxes in Figure la represent the pre-selected scanning resolution, or the pixel size, and the black box represents a spot of color on the original image. In this example, when scanned, the spot of color would fall on the intersection of the four pixels. As a result, the scanner would combine the black color with the white background and produce a digital image that consists of four gray pixels, as in Figure lb. In essence, the process of digitization has produced a completely new color that was not present in the original document. If, however, the scanning resolution were doubled, as in Figure le, then the black spot would no longer fall on the intersection of four large pixels, but completely fill four smaller pixels. In this instance, the black spot on the white background would be reproduced exactly, with no new colors added to the digital image. Rarely do all the pixels in a digital image fall completely within the area dominated by one color or another. Usually there are a number of pixels that fall along the line separating areas of different colors. These are referred to in this paper as "edge-pixels." For example, Figure 2 depicts two heavy black lines on a white background. The line was originally drawn in ClarisDraw at 72 dpi and printed on a 360 dpi ink jet printer. The hard-copy was then scanned at 9 dpi. The digital image file was then imported into ClarisDraw where it was placed on the same page as the 72 dpi version for purposes of comparison. Because the lines are diagonal in relation to the pixel grid, there are many edge-pixels in the 9 dpi version which fall both within the body of the line and within the vvhite background. Notice that these edge-pixels are various shades of gray, the darkness of which is dependent upon how much of the pixel fell 9 dpi \•: ithin the body of the line. In other words, those edge-pixels that have 72 d pi the majority of their area covered by the line are darker than those which F1g11re 2. Co111pariso 11 of1 111ages sca1111ed at are mostly within the \Nhite background. In this instance, the scanner has differe11 t reso/11 t w11~. produced a digital image that contains very few black pixels while pro­ ducing many shades of gray that were not present in the original image. This becomes very apparent when viewing the histograms for these t•..vo images (Figure 3, page 6). The x-axes of these histograms represent the color values from 0 (black) on the left to 255 (white) on the right. The y-axes represent the number of pixels in the image that have that particu­ lar \'alue. The graph for the 72 dpi version clearly shows that there are only t\vo colors present within that image, namely black and white. There is a tall, thin line at the extreme right end of the x axis of this histogram-it represents the number of white pixels. Conversely, the line at the extreme left end of the x-axis represents the number of black pixels in the image. Notice that there are no other values depicted on this graph, meaning that there are no other colors present within the image. However, on the histogram for the 9 dpi version, there are lines all along the graph, mean 6 cartographic perspectives Number 23, Winter 19%

ing that there are a substantial number of pixels that have intermediate values-essentially, they are various shades of gray. This principle of edge-pixels can have some very interesting effects on color images. On very colorful originals, such as full color maps and color air photos, there could be a great number of edge-pixels present in the digital image. For example, Figure 4 (page 9) portrays four images of the same place from the National Topographic Series 1:50,000 Bath sheet (number 31C/2, edition 5, 1979) scanned at increasing resolutions. This image is a detail of a park (see the location map), the original size of which on the map was 3.74 mm by 6.78 mm (0.147 inches by 0.267 inches). Notice in the 75 dpi version, there is a line of brown and tan pixels along the right and bottom edges of the image while the rest of the image consists of green and taupe pixels. In the 150 dpi version, the brown line on the right side has become purple. This is very intriguing, for the NTS legend contains eight colors-red, orange, blue, brown, black, gray, green, and white. There are no features portrayed in purple on the original map sheet. This means that the colors present in the original which are con­ tained within the purple pixel area were combined by the scanner to produce new colors that are not found on the original map. Also notice that the interior portion of the image has a greater variety of color com­ pared to the 75 dpi version. Again, most of these shades are peculiar to the digital image and are not found on the original document. Like the 75 dpi and 150 dpi versions of this image, the 300 dpi and 400 dpi versions also contain many artifactual colors due to the edge-pixel as pixel size decreases ... the phenomenon. Close scrutiny reveals that there is a small but significant effect of the edge-pixel number of pixels in the body of these images that are turquoise or aqua; phenomenon is mitigated and a neither of these colors are represented in the legend of the original docu­ closer reproduction of the colors ment. Furthermore, the right and bottom edges are no longer brown, as in of the original document is the the 75 dpi version, or purple, as in the 150 dpi image, but a mottled inevitable result. collection of red, pink, gray, tan and brown pixels; some of these colors are in fact represented in the legend. Therefore, while these higher resolution images both contain artifactual colors, because more and more pixels are beginning to portray colors which are in the legend of the original, one can conclude that there is a positive relationship between scanning resolution and the quality of color reproduction. In other words, as pixel size decreases (or as scanning resolution increases), the effect of the edge-pixel phenomenon is mitigated and a closer reproduction of the colors of the original document is the inevitable result. The histograms of these images highlight the differences in color reproduction between the increasing scanning resolutions. Photoshop 3.0 will generate a separate histogram for each color channel, plus a gray histogram that represents the overall brightness of the image (Figure 5). The histograms for the higher resolution images are denser because they portray more pixels, but the general trends between the histograms can be L Number 23, Winter 1g% cartograpliic perspectives 7 compared and analyzed. For example, all the histograms for the 75 dpi image depict a relatively narrow color range with a spike that dominates the graph. As the resolution increases, the color range widens and the spike becomes less dominant. This indicates that the digital images are portraying many more subtle variations of color. Furthermore, as indi­ cated by the "mean" color value, the images are becoming brighter as the resolution increases. Therefore, as the only difference between the digital images is the scanning resolution, the differences in the histograms are products of the increased resolution. When viewing the images, the user may be hard pressed to find any substantial color variations between higher resolution and lower resolu­ tion scans; as demonstrated with the histograms of the color images, the

differences are very subtle. Indeed, how the image is viewed will have an impact on the theoretical "gain" in color reproduction; the gain is most noticeable when the image is greatly magnified. That is, if the image is to be viewed on a 1 to 1 magnification ratio as a paper print out, then the increased quality of the color will be virtually unseen. However, if the image is magnified on a high resolution computer screen, then the differ­ ences are most conspicuous.

CONCLUSIONS When digitizing a color image, the digital preservationist must ask him I herself the following question: are the images to be used for research purposes, or for browsing and I or indexing? The answer to this question will have an impact upon the resolution and standards which will be used in the digitization process. Different researchers have different uses for digital images. If the image is to be used in an application where the quality is not critical, for example as an index image, then considerations other than color reproduction, such as file size, compression ratio, and minimum legibility requirements, must take priority. However, another researcher may be concerned with the paper stock on which the original work was produced. He/ she may be interested in identifying the water­ mark, or seeing the chain lines and laid lines in an attempt to identify the paper manufacturer. Likewise, another researcher may be interested in the inks and dyes used in the printing process. In these instances, digital images are typically used by researchers either in lieu of handling the fragile originals or because the originals are not easily accessible due to their location, and under these circumstances, better color reproduction will be invaluable to the researcher. If the digital image contains a large number of artifactual colors from the digitization process the usefulness of the image is reduced dramatically. Under most circumstances, images intended for research purposes ... images intended for research need much more accurate color reproduction than those intended for purposes need much more browsing or indexing. It is recommended that research images be digi­ accurate color reproduction tized using the highest possible quality standards for color reproduction. As one of the tenets of digital preservation is to produce a faithful replica than those intended for of the original, it is ironic that most research into digital imaging is browsing or indexing. concerned with finding that quality which is simply "good enough." That is, in the search for the "perfect" compromise between file size and image quality, all too often the priority is to minimize the disk space required to store an image rather than find the optimal image quality. It is impossible for a digital preservationist today to know what will be required of digital images in the future. Therefore, if the image is to be used for archival/ research purposes, it is imperative that the image be captured at the highest possible quality. Given that the technology for capturing, storing, retrieving and viewing images is constantly improving, images that are "good enough" today likely will be wholly inadequate in the near future.

Martin van Wyss The proliferation of home and business computers has resulted in a Hybrid Designs dramatic increase in the number of animated maps in private, institu­ 579 Franklin Street tional, commercial, and academic settings. As authoring software that Cambridge, MA 02139 allows the production of such maps becomes cheaper and easier to use, [email protected] animated maps will continue to become more numerous and sophisti­ cated. This increase in the number and complexity of animated maps and the resultant need to automate their design and production calls for novel cartographic approaches. This paper stems from a project involv­ ing the design of animated maps for a typical multimedia product. An important element of the animations were the transitions between maps of different scales. An explanation of an algorithm to choose map scales suggests how aesthetic judgments can be incorporated into the auto­ mated production flow for the finished product.

ANIMATED MAPS, ynamic maps can take the form of animated maps, interactive maps, INTERACTIVE MAPS, AND D and combinations of the two. I will use the term dynamic to refer to HYBRID MAPS the broad category of maps that can change during viewing. Animated maps offer little user control and present changes of map attributes in a manner that is either logically or chronologically linear. Interactive maps allow the user to adapt or control the map display. Map design strategies for dynamic maps have categorized the maps according to the primary characteristic exploited by the temporal dimen­ sion: sonification, animation, and interaction (DiBiase et al. 1992). Sonification involves the use of sound to represent data (Krygier 1994), but since there is no fundamental role played by map scales in this type of map sonic maps will not be addressed in this paper. Scale changes are, however, useful and well-suited to animated and interactive maps. The animation in which there is "the illusion of motion created from a sequence of still images" (DiBiase et al. 1992) is perhaps the most com­ mon form of map animation. These maps, commonly found on television newscasts and educational computer software, are linear presentations of a series of frames or static map images. Scale changes are particularly useful for illustrative purposes in this sort of animated narrative (Dorling 1992b, 633). The animated maps discussed in detail later in this article are of this type. Much of the literature on animation has emphasized its use for repre­ senting time series data. Some attention, however, has also been given to the role of animation and interaction for exploring non-temporal data (e.g. DiBiase et al. 1992, Darling 1992a and 1992b). In the context of what he calls animating space, Darling argues that changing the scale of the map is the only way to properly examine large and complex data sets (Darling 1992a, 1992b). When the change over time of the mapped data is too complex for the observer to notice both spatial and temporal patterns, Dorling argues for temporally static maps, or maps that show a time slice from a particular moment. Zooming and panning across these maps allows the examination of details in cases where aggregation of data is unacceptable. This strategy of animating space instead of animating time Number 23, Winter 19% cartographic pcrspcctil1cs 13 is particularly useful in the social sciences where extreme variations in d ata values are fo und over sm all areas. Unlike animated maps, interactive maps have no fi xed structure; the user interacts w ith the display to view different scenarios or representa­ tions. The interaction allo i.vs the user to question data to gain a better understand ing, or to tailor the display to match the knowledge the user brings to the map. Monmonier (1991, 4) points out the need for an "anti­ d ote" to the "d angerous abuse" that his Atlas Touring and other "care­ Unlike animated maps, interac­ fully o rchestrated sequence(s) of persuasive graphics" invite.

Kraak mentions the impo rtance of geometric transformations in the of three-dimensional maps, citing their complexity and the difficulty of the human mind to process depth clues. "Manipulati on of the maps is not restricted to their content, but also includes their position in three-dimensional space" (Kraak 1993, 13- 14). Geometric transformations like zooming, scaling (both involve scale changes) and rotating a re necessary in order to take ad vantage of the added info rma ti on in the terrain model. Since the display method-the monito r- is two-dimensional, interaction is necessary to "see" the infor­ mation added by the three-dimensional model. The impo rtance of smooth scale changes in dynamic interaction and animated maps is underscored by a report (Harwood 1989) on d ynamic map displays for heli copter fli ght. Pilots used on-board map displays for a vari ety of tasks, and their success was shown to improve when the m ap displays were smooth and unobtrus ive. Similarly, researchers have found "greater user preference for and confidence in representations which provide smooth change between images" displayed on computer moni­ tors (Rheingans 1992).

Scale changes proved to be invaluable in keeping map viewers oriented DESIGN FOR A MULTIMEDIA and the narrati on coherent in thirty animated ma ps commissioned by ENCYCLOPEDIA Grolier for its New Grolier Multimedia E11cyclopedia on CD-ROM (Grolier 1994). This encyclopedia is aimed at adult and high school-aged home users, and the animated maps were a major selling point fo r the 1994 version. The maps portray major world events such as the Gulf War, the Korean War, Yiagell an's circumnavigation of the world, and the spread of overl and routes across the colonial United States. The animations include audio narration and also text narration for micro-computers that have no sound capability. Flashing symbols and areas are used to highlight important static map informati on while movement is represented w ith fl ow arrows and sprites. 1 The p ublisher's prio rities were in creating a product of high aesthetic quality and visual excitement. David DiBiase has written in detail about the project (DiBiase 1994). The design of the maps was intriguing because guidelines and conven­ tions for the medium have not yet been established. Another challenge was the fact that the publishe r fa iled to determine how well the anima­ tions, deli vered in the form of Macromedia Director movies, would survive the fi nal transition to Q uickTime m ov i es. ~ Finally, Grolier 's assumptions about the ty pical user's computer configuration limited, for example, the number of frames that could be used and the size of the maps on screen .

I. Gersmehl (1990) provides a glossary of this and other terms frequently used in animations.

MAP DESIGN The pressure of designing fifteen animations in only twelve weeks forced us to confront many issues in a hurry. What elements that are common to static maps should be included? Which elements are redundant and should be abandoned? While these and similar issues regarding the transition frum slalic Lo animated mapping have been noted (Cartwright 1994), few guidelines or design principles exist. Gooding and Forrest are clearly correct when they state that"... if video maps are to be used effectively, they should be developed specifically for that medium" (1990). Similarly, our animated maps had to be designed for the desktop personal computer medium using CD-ROM. Resolution was limited to the 72 pixel- per- inch monitor standard to contain file size and the amount of required storage space on the CD-ROM. The map area was limited to a field four hundred pixels wide and hvo hundred eighty pixels high The most significant and funda­ (roughly 5.5 by 4 inches) to ensure that the animations fit on the smallest mentally unique desig11 concern Macintosh screens. This made the choices of map elements critical. Too for the maps was the possibility many elements on the map display seemed to clutter the geographical information. A legend was one of the elements we found to be superflu­ of using time as a variable to ous for our animated maps. It was more effective to explain an event and express i11formatio11 . .. its players with spoken and written narration than by filling the map with placename lettering. The most significant and fundamentally unique design concern for the maps was the possibility of using time as a variable to express information (DiBiase et al. 1992, Kousoulakou and Kraak 1992, Kraak and MacEachren 1994). The use of animation time to correspond with historical time was fw1damental to the animations produced; the stories were usually told in a chronologically linear fashion. Flashing symbols to symbolize events such as battles drew the viewer's attention to small places on small-scale maps. Repetition of animation sequences represented repeated attacks on cities. The timing of the story (through the manipulation of how long an animation frame was displayed) was important for making the stories comprehensible. Timing was also used for dramatic effect to underscore the numbers of people killed in wars. The display of different maps at different scales over the course of the animation was essential to keeping the narratives coherent, and appropri­ ate scale changes were the crucial link between these maps. Changing scale meant that the story could be played out on a map that was always at the appropriate scale for the subject matter. Making the scale change smooth provided a link between the maps and kept the viewer spatially oriented, providing a coherent narrative while keeping the viewer's attention focused on the story subject and not on the scale change.

THE ROLE OF SCALE The nature of the events to be animated demanded that we use maps at CHANGES different scales. The animation of the Korean War, for example, opens with a map of southeast Asia to acquaint the viewer \o\oith the location of Korea. Narration then switches to a map of Korea on which troop move­ ments can be shown. The animation of the United States Revolutionary War repeatedly changes scale. A small-scale map shows the shape and size of the original colonies to set the scene, then large-scale maps of troop movements in, for example, the New York-New Jersey region express the local and regional events. Traditional static maps use insets to show where in the world the featured place is, or to show an area of detail. The nature of animations, however, makes these inset maps extraneous and pointless (and a cause of eye strain in a window less than six inches wide). Instead, maps can be presented as dynamic i11 sets at the scale that is appropriate to the thematic information. Over time, the display can shift from one map to another at a Number 23, Winter 19% cartograplzic perspectives 15 different scale, thereby overcoming the spatial constraints that apply to the printed page. This is an example of the effective exploitation of the temporal dimension of animations. An abrupt switch in an animation from one map scale to the next without a transition would be disruptive to the animation and to the flow of information, obscuring the spatial relationship between the maps, thereby disorienting the viewer. Therefore, there is a need for transition techniques such as :00111-i11s, :00111-011ts, and exploding insets (terms to be Map animations, therefore, defined below) to provide the link between different maps. As is the case need to shift between different with many map design choices (like those concerning typeface, layout, and color palette), the effectiveness of these transitions lies in their ability maps without losing the map to allow the map reader to remain focused on the theme of the map. Good user's attention to the map design avoids attracting the viewer's attention to individual elements transition. by ensuring that the map elements remain transparent. Map animations, therefore, need to shift between different maps without losing the map user's attention to the transition. One way to accomplish this is by using a high number of frames in order to give the impression of continuous change. This ideal situation would be possible \·vith unlimited memory space, but limits on the num­ ber of frames allowed are imposed at every link in the chain from the cartographer's computer to the display on the consumer's monitor. Animation files, especially when they include audio tracks as Grolier's did, require substantial amounts of storage space, a function of the length of the animation, the size of the animation window on the screen, audio bit depth (a function of the variation allowed in pitch, timbre, etc.), and the color bit depth (a function of the number of colors used in the pal­ ette).' Even when storage space isn' t the issue, only the fastest microcom­ puters can move from one frame to the next at a rate faster than the eye can perceive a change on the screen. Finally, the monitors on which these animations are viewed can only refresh (or paint the next image onto) their screens at a certain limited frequency determined by their scan rate. Inevitably, then, a sophisticated viewer is able to distinguish beh-veen individual frames. But if the transition is well designed, the viewer's attention will be kept on the map and not on the difference between indi\·idual frames. Since technologic constraints demand that the number of frames remain small, the care put into the selection of transition frames must be great if transitions are to play their role inconspicuously. 4

The simplest example of a scale change that we will consider is a zoom-in AN EQUATION TO DESCRIBE from a small-scale map to one of larger scale. Each map in the zoom is at THE SCALE CHANGE a larger scale than the previous one, and its land area is smaller than the previous map's area. There is always only one map visible, and that map takes up the entire animation ·window. Thematic content determines the map scales at the beginning and end of the zoom. The number of desired steps, or frames (usually a compro­ mise between memory limits and desired frame resolution), must also be known. Regular intervals from one scale to the next, as defined by

Equation 1 and exemplified with a hypothetical zoom in 1 (page Figure 1 18), are easy to calculate but yield a scale change that is uneven. When David DiBiase, project manager and director of Deasy GeoGraphics Studio at Penn State University and I viewed this zoom on a Figure 2 monitor we judged that the zoom was inappropriate. The change in land area covered by the first frames was too great, and it was too little at the end of the zoom. Figure 1, for example, shows a significant leap in size of Long Island between the first two frames, while its size changes only slightly at the end of the zoom-in. We then drew an exponential curve based on the equation y=x2 on graph paper and read off the intermediary scales for the frames between our known starting and ending map scales (Equation 2). This seemed logical since the equation describes the relationship between the scale and the area covered by any map. But this equation we also deemed inappro­ priate. The size of New Jersey (see Figure 2) still changed too much at the start of the zoom-in and too little at the end. Figure 4 Interpolating intermediate scales with logarithmic paper yielded zooms that we judged appropriate. Figure 3 shows how Long Island's size changes at a steady rate when the map scales are determined by Equation 3. All zooms and exploding insets made thereafter were made by drawing a straight line between the starting and ending points of the scale change on logarithmic paper. Zoom-outs were used frequently in the animations when the map scale decreased. They were constructed exactly like zoom-ins but with order of frames reversed. The exploding inset (Figure 4) is another transition that allows the animation to move to a map of larger scale. Like a traditional inset on a static map, the explod- Number 23, Winter 1996 cartographic perspectives 17 ing inset begins with a small-scale map with a box drawn around the Equation 1 area that is to be shown at a larger scale. The small-scale map re- mains in the background as the scale - scaleb ) scale = scale + n ( end eg large-scale map section of interest n beg N increases in size until it is occupy­ ing the entire animation window, blocking out the small-scale map. The same logarithmic equation Equation 2 used for zooms describes explod­ ing insets. Whereas map size scalen = ( scalebeg + n ( scaleend - scalebeg ) )2 remains constant while land area N changes for zooms, the inverse is true for exploding insets: the land area covered by the map is fixed Equation 3 while the map itself grows (in the case of the exploding inset) or shrinks (imploding inset). log(scaleb )+n(log(scaleend) - log(scalebeg)) scalen = 10 eg N Tables 1-3 (page 18) track the scales of four intermediate itera- tions of a six-step exploding or imploding inset. The scale factor represents the relationships where: between each iteration and the n = the iteration in the scale change starting map scale. The next column represents the portion of N = total number of steps in scale change the original map's area taken up scalebeg = map scale at beginning of scale change by each subsequent map of the scaleend= map scale at end of scale change same region at a smaller scale. The crucial column is the last one which shows how the size of each map varies from the previous map's size. For the logarithmic equation this number is constant, indicat­ ing that a transition that seems smooth is one in which the inset "blows up" or "collapses" at a steady rate. The production staff and the rest of the Deasy staff were responsible for deciding which zooms were appropriate. The project's comme rcial nature and short production time-frame meant there was no possibility of having outside revie>vers or focus groups. The discovery of constant change of area for the logarithmic equation confirmed our subjective decision that this equation yielded the most appropriate scale change. Ours was an aesthetic judgment that, according to the tables, seemed to have an objective basis in the inherent relationships between map scale and map area.

Generalization of features and linework as scales change is an important GENERALIZATION AND PER­ consideration. Some researchers argue that a feature like a city could be CEIVED MAP SCALE represented by three different symbols depending on the scale. "As you zoomed in on the city, its appearance would jump from one representa­ tion to the other" (Dorling 1992a, 218). This is acceptable, Darling argues, because the change is not unexpected, and because it is a very efficient way to show scale changes without having to recalculate images on the fly. Although this strategy is acceptable for an interactive environment where the exact scale that the user chooses cannot be anticipated by the programmer, this solution is neither appealing nor necessary in non- 18 cartogmpl1ic perspectives Number 23, Winter 19%

The small size of our animations meant that generalization was determined by the software, not the map scales. Final assembly was done in Di rector \.vhere all lines at all scales needed a width of a t least one pixel in order to not become interrupted. Therefore after scaling the maps in Aldus Freehand according to the equation, line weights were made constant in all the maps of the zoom, regardless of their scale. The low resolution of 72 pixel- per-inch monitors limited the amount of detail permissible. As increased computer power and improved compression rates will all ow higher resolution, animated map displays will, in turn, increase in size, increasing the need for appropriate generalization levels as scales change. Ti:i pfer's radical law (Ti:i pfer and Pilliwizer 1966) is a theoreti cal proposal that suggests the degree of generali zation for differ­ ent map scales. His equation could be incorporated into an algorithm p roducing scale changes for animati ons. Experi ence from this project, however, wou ld indicate that a logarithmic equation might be more appropri ate.

Adaptation of traditional cartographic techniques to mapmaking with CONCLUSION animated media needs to be considered on a case-by-case basis. While many conventions need to be retained, other elements are redundant and can be eliminated from animated maps. The inset map is an example of a fea ture common to static maps that serves no useful role in animated maps. Its replacement, the dynamic inset map, appears to be useful and intuitive for the viewer ·when its transitions are designed well. Animated maps and interactive dynamic maps can both be enhanced w ith appropriate scale changes, regardless of the a pplication. Zooms between maps at different scales all ow the user to investigate the mapped subject close up, or all ow the animation to continue to the next section of the story while the user remains geographically oriented . The logarith­ mic equation offered in this paper is a useful step in the automation of the design of such scale changes so that these transitions can be the incon­ spicuous links that make possible a cohe rent, informati ve narrative.
