Similar to the European work, we emphasize reference maps. In contrast to the Europeans' focus on data generalization, we emphasize changes to the map display, including symbol design or symbol modification. We also work from databases compiled at multiple resolutions rather than constructing all representations from a single high-resolution database. We report results demonstrating how symbol change combined with selection and elimination of subsets of features can produce maps through almost the entire range of map scales spanning 1:10,000 to 1:5,000,000. We demonstrate a method of establishing specific map display scales at which symbol modification should be imposed. We present a prototype decision tool called ScaleMaster that can guide multi-scale map design across a small or large range of data resolutions, display scales, and map purposes.

[Termes IGN] visualisation 3DRésumé : (Auteur) Fly-over animated terrain maps have become increasingly popular as overview / reference maps, despite years of research that demonstrates how easily disoriented viewers can become when using them. This project developed four kinds of visual "orientation cues" which are designed to decrease viewer disorientation, and which could be directly embedded into the map scene similar to heads-up-display technology. The effectiveness of these orientation cues was tested. Compared to a map with no orientation cues, the presence of the monorail and landscape grid orientation cues halved subjects' directional error; the horizon compass cue virtually eliminated directional error. Correspondingly, subjects were significantly more confident in their answers and thought the tasks were significantly easier in the presence of these three cues. Similar results were found in the ability of subjects to trace their flight path, although their improvement is less pronounced. However, the fourth orientation cue, landmark labels, was ineffective and created similar (or worse) performance than the map with no orientation cues.

The first objective of the evaluation, which is addressed by a formal usability test, is to evaluate the performance of the test participants on pre-defined exploration tasks. The second objective is to attempt to better understand how the participants explore the spatial dataset. This objective is addressed in the exploratory usability part of the experiment, where participants are given free hand to perform exploration in any way they want. The study introduces a low-cost methodology for performing usability evaluation, which uses simple and inexpensive methods for data collection and analysis, yet proves to be adequate to identify potentials and problems of the tool.

[Termes IGN] SIG participatifRésumé : (Auteur) This paper characterizes efforts by nonprofit organizations to access spatial data developed by government agencies. It is based on research conducted in California, a U.S. state that is positioned at the forefront of nonprofit usage of GIS. The research, conducted over a ten-year period, followed six best practices case studies of small conservation and environmental organizations using GIS. Case study research is analyzed in a framework developed from the literature on public participation GIS and inter-organizational GIS. The research revealed that access was structured by technical details, such as adjusting agencies' thematic categories, fluctuations in foundation funding and other organizational/political issues, and inter-organizational linkages in the emergent spatial data intermediary sector. Overall, access was conditioned by the legal and economic regimes in which the cases conducted their advocacy. Ultimately, access to data profoundly shaped GIS applications and nonprofit activities, occasionally shifting or even precluding activism, provoking creative mechanisms to obtain data, or inducing innovative usage of available data.
