Current Trends in Vector-Based Internet Mapping: a Technical Review
Chapter 3 Current Trends in Vector-Based Internet Mapping: A Technical Review Christophe Lienert, Bernhard Jenny, Olaf Schnabel, and Lorenz Hurni Abstract Possibilities and limitations of Internet cartography software largely depend on the pace set by the software industry. The variety of commercial and non-commercial software caters for the needs of a continuously growing mapping community, including both professional and amateur cartographers. This chapter provides an overview of state-of-the-art technologies for vector-based Web- mapping as of the beginning of 2011. Both proprietary and open format technologies are discussed for vector data rendering in browsers, highlighting their advantages and disadvantages. The discussed technologies are Adobe Flash, Microsoft Silverlight, Scalable Vector Graphics (SVG), JavaFX, Canvas, and WebGL. The chapter also discusses client and server side frameworks which provide Application Programming Interfaces (APIs) for creating custom interactive maps, mainly by overlaying raster images with vector data. 3.1 Introduction Internet maps are the major form of spatial information delivery, as the Internet is today the primary medium for the transmission and dissemination of maps (Peterson 2008). For map authors, the maze of available techniques for creating and distributing Web maps is overwhelming, while authoring tools for Web-maps meeting the demands of high-quality cartography are difficult to find. Map authors may choose between GIS and graphics software products to create maps for the Internet, but these off-the-shelve maps oftentimes fall short of effectively convey- ing information. There are three main reasons for this shortcoming: (a) the design of these maps sometimes does not take into account the specific limitations of digital displays (Jenny et al., 2008); (b) the maps are often restricted in using standard C. -

Of the many types of maps, thematic maps perform an important function due to the wide possibilities of adapting their content to current needs. The limitation of classic maps is their two-dimensional nature. In the era of rapidly growing methods of mass acquisition of spatial data, the use of flat images is often not enough to reveal the level of complexity of certain objects. In this case, it is necessary to use visualization in three-dimensional space. The motivation to conduct the study was the use of cartographic projections methods, spatial transformations, and the possibilities offered by thematic maps to create thematic three-dimensional map imaging (T3DMI). The authors presented a practical verification of the adopted methodology to create a T3DMI visualization of Citation: Dabrowski, P.S.; Specht, C.; Specht, M.; Makar, A. the marina of the National Sailing Centre of the Gda´nskUniversity of Physical Education and Sport Three-Dimensional Thematic Map (Poland). -
Members | Diagnostic Imaging Tests
Types of Diagnostic Imaging Tests There are several types of diagnostic imaging tests. Each type is used based on what the provider is looking for. Radiography: A quick, painless test that takes a picture of the inside of your body. These tests are also known as X-rays and mammograms. This test uses low doses of radiation. Fluoroscopy: Uses many X-ray images that are shown on a screen. It is like an X-ray “movie.” To make images clear, providers use a contrast agent (dye) that is put into your body. These tests can result in high doses of radiation. This often happens during procedures that take a long time (such as placing stents or other devices inside your body). Tests include: Barium X-rays and enemas Cardiac catheterization Upper GI endoscopy Angiogram Magnetic Resonance Imaging (MRI) and Magnetic Resonance Angiography (MRA): Use magnets and radio waves to create pictures of your body. An MRA is a type of MRI that looks at blood vessels. Neither an MRI nor an MRA uses radiation, so there is no exposure. Ultrasound: Uses sound waves to make pictures of the inside of your body. This test does not use radiation, so there is no exposure. Computed Tomography (CT) Scan: Uses a detector that moves around your body and records many X- ray images. A computer then builds pictures or “slices” of organs and tissues. A CT scan uses more radiation than other imaging tests. A CT scan is often used to answer, “What does it look like?” Nuclear Medicine Imaging: Uses a radioactive tracer to produce pictures of your body. -

Designing and Implementing a Geographical Information System
DESIGNING AND IMPLEMENTING A GEOGRAPHICAL INFORMATION SYSTEM A Guide for Managers of Area-wide Pest Management Programmes DESIGNING AND IMPLEMENTING A GEOGRAPHICAL INFORMATION SYSTEM A Guide for Managers of Area-wide Pest Management Programmes IAEA, VIENNA, 2006 IAEA/FAO-GIS © IAEA, 2006 Printed by the IAEA in Austria April 2006 FOREWORD Over the past two decades, the use of computer software and mapping methods known as geographical information systems (GIS) has been adopted by an ever growing variety of professionals. Every activity that deals with location dependent information can use GIS, and agriculture is no exception. The potential of GIS and remote sensing (RS) to facilitate the planning and implementation of area- wide integrated pest management (AW-IPM) programmes is enormous but unfortunately, these methods are still much underused. AW-IPM programmes, especially those that integrate the sterile insect technique (SIT) with other surveillance and control methods, would benefit considerably by drawing on GIS/RS. These programmes are often implemented over large areas of even tens of thousands of square kilometres, where surveillance methods are deployed and large data sets are systematically generated on a daily basis. The acquisition of geo-referenced data sets on pest presence/absence, relative abundance, disease prevalence, crop damage, etc., that will allow accurate spatial and temporal analysis is important for proper and timely decision making to efficiently plan and implement any operational pest management programme. Animal health and plant protection officials and pest control programme managers might be intuitively aware of the importance of employing GIS as an analytical tool. However, they often lack a deeper understanding of its capabilities. -
Visualizing Change: Using Cartographic Animation to Explore Remotely-Sensed Data
30 cartographic perspectives Number 39, Spring 2001 Visualizing Change: Using Cartographic Animation to Explore Remotely-Sensed Data Mark Harrower This research describes a geovisualization tool that is designed to facilitate exploration of satellite time-series data. Current change-detec- Department of Geography tion techniques are insufficient for the task of representing the complex & GeoVISTA Center behaviors and motions of geographic processes because they empha- size the outcomes of change rather than depict the process of change The Pennsylvania State itself. Cartographic animation of satellite data is proposed as a means University of visually summarizing the complex behaviors of geographic entities. 302 Walker Building Animation provides a means for better understanding the complexity of geographic change because it can represent both the state of a geograph- University Park, PA 16802 ic system at a given time (i.e. its space-time structure) and the behavior [email protected] of that system over time (i.e. trends). However, a simple animation of satellite time-series data is often insufficient for this task because it overwhelms the viewer with irrelevant detail or presents data at an inappropriate temporal and spatial resolution. To solve this problem, dynamic temporal and spatial aggregation tools are implemented with the geovisualization system to allow analysts to change the resolution of their data on the fly. These tools provide (1) a means of detecting structures or trends that may be exhibited only at certain scales and (2) a method for smoothing or filtering unwanted noise from the satellite data. This research is grounded in a delineation of the nature of change, and proposes a framework of four kinds of geographic change: location, size/extent, attribute and existence. -

ABSTRACT Animation is an important method of communicating information that lends itself to cartographic display. Exploration of this medium resides at the forefront of cartographic research. The purpose of this project has been to develop a viable cartographic animation process employing hardware and software currently available in the Geographic Information and Analysis Laboratory (GIAL) at the Department of Geography, State University of New York at Buffalo. -
Webservices for Animated Mapping: the Timemapper Prototype
Chapter 14 Webservices for Animated Mapping: The TimeMapper Prototype Barend Kobben,€ Timothe´e Becker, and Connie Blok Abstract Within a larger aim of improving automated vector animated mapping, the main objective of this research was to look into the possibility of combining two technologies: distributed webservices and animated, interactive vector maps. TimeMapper was developed as a prototype for an OGC-compliant Web Map Service implementation that serializes spatio–temporal data from a database backend as Scalable Vector Graphics. The SVG is used in a web browser to show animated maps with a built-in advanced user-interface. This interface allows the user to interact with both the spatial and the temporal dimensions of the data. The potential and limitations of the TimeMapper prototype were explored using Antarctic iceberg movement data. The prototype can be explored on the TimeMapper website (http://geoserver.itc.nl/timemapper/). 14.1 Introduction The motivation for building the TimeMapper prototype was the improvement of automated animated vector mapping. We are interested in animation, because interactive animated mapping has been pointed out, by Andrienko et al., (2003) among others, as the only technique to be generically applicable to visually analyze the dynamic nature of real world phenomena. We want to facilitate the production of animated maps from spatio–temporal data to a format suitable for Internet dissemination, automatically and directly.To achieve that, we looked specifically into the possibilities of the loose coupling of distributed webservices with animated, interactive vector maps.
