Inviwo — a Visualization System with Usage Abstraction Levels
IEEE TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS, VOL X, NO. Y, MAY 2019 1 Inviwo — A Visualization System with Usage Abstraction Levels Daniel Jonsson,¨ Peter Steneteg, Erik Sunden,´ Rickard Englund, Sathish Kottravel, Martin Falk, Member, IEEE, Anders Ynnerman, Ingrid Hotz, and Timo Ropinski Member, IEEE, Abstract—The complexity of today’s visualization applications demands specific visualization systems tailored for the development of these applications. Frequently, such systems utilize levels of abstraction to improve the application development process, for instance by providing a data flow network editor. Unfortunately, these abstractions result in several issues, which need to be circumvented through an abstraction-centered system design. Often, a high level of abstraction hides low level details, which makes it difficult to directly access the underlying computing platform, which would be important to achieve an optimal performance. Therefore, we propose a layer structure developed for modern and sustainable visualization systems allowing developers to interact with all contained abstraction levels. We refer to this interaction capabilities as usage abstraction levels, since we target application developers with various levels of experience. We formulate the requirements for such a system, derive the desired architecture, and present how the concepts have been exemplary realized within the Inviwo visualization system. Furthermore, we address several specific challenges that arise during the realization of such a layered architecture, such as communication between different computing platforms, performance centered encapsulation, as well as layer-independent development by supporting cross layer documentation and debugging capabilities. Index Terms—Visualization systems, data visualization, visual analytics, data analysis, computer graphics, image processing. F 1 INTRODUCTION The field of visualization is maturing, and a shift can be employing different layers of abstraction. -
3B – a Guide to Pictograms
3b – A Guide to Pictograms A pictogram involves the use of a symbol in place of a word or statistic. Why would we use a pictogram? Pictograms can be very useful when trying to interpret data. The use of pictures allows the reader to easily see the frequency of a geographical phenomenon without having to always read labels and annotations. They are best used when the aesthetic qualities of the data presentation are more important than the ability to read the data accurately. Pictogram bar charts A normal bar chart can be made using a set of pictures to make up the required bar height. These pictures should be related to the data in question and in some cases it may not be necessary to provide a key or explanation as the pictures themselves will demonstrate the nature of the data inherently. A key may be needed if large numbers are being displayed – this may also mean that ‘half’ sized symbols may need to be used too. This project was funded by the Nuffield Foundation, but the views expressed are those of the authors and not necessarily those of the Foundation. Proportional shapes and symbols Scaling the size of the picture to represent the amount or frequency of something within a data set can be an effective way of visually representing data. The symbol should be representative of the data in question, or if the data does not lend itself to a particular symbol, a simple shape like a circle or square can be equally effective. Proportional symbols can work well with GIS, where the symbols can be placed on different sites on the map to show a geospatial connection to the data. -

The New Plot to Hijack GIS and Mapping
The New Plot to Hijack GIS and Mapping A bill recently introduced in the U.S. Senate could effectively exclude everyone but licensed architects, engineers, and surveyors from federal government contracts for GIS and mapping services of all kinds – not just those services traditionally provided by surveyors. The Geospatial Data Act (GDA) of 2017 (S.1253) would set up a system of exclusionary procurement that would prevent most companies and organizations in the dynamic and rapidly growing GIS and mapping sector from receiving federal contracts for a very-wide range of activities, including GPS field data collection, GIS, internet mapping, geospatial analysis, location based services, remote sensing, academic research involving maps, and digital or manual map making or cartography of almost any type. Not only would this bill limit competition, innovation and free-market approaches for a crucial high-growth information technology (IT) sector of the U.S. economy, it also would cripple the current vibrant GIS industry and damage U.S. geographic information science, research capacity, and competitiveness. The proposed bill would also shackle government agencies, all of which depend upon the productivity, talent, scientific and technical skills, and the creativity and innovation that characterize the vast majority of the existing GIS and mapping workforce. The GDA bill focuses on a 1972 federal procurement law called the Brooks Act that reasonably limits federal contracts for specific, traditional architectural and engineering services to licensed A&E firms. We have no problem with that. However, if S.1253 were enacted, the purpose of the Brooks Act would be radically altered and its scope dramatically expanded by also including all mapping and GIS services as “A&E services” which would henceforth would be required to be procured under the exclusionary Brooks Act (accessible only to A&E firms) to the great detriment of the huge existing GIS IT sector and all other related companies and organizations which have long been engaged in cutting-edge GIS and mapping. -
