Visualization
tool/system development
In the
first of three papers focusing on visualization tool/system development,
Andrienko and Andrienko present a fully web based exploratory environment.
They describe and present Decartes, a program that allows the user
to dynamically manipulate the representation of socio-economic data.
After a user selects variables for presentation, the program presents
a set of sound cartographic solutions, then allows the user to explore
the data in many different ways.
The
second paper in this section, Peterson's contribution, offers a perspective
on some of the new options the WWW has to offer for presenting dynamic
/ and interactive geo-data. He discusses active, JavaScript based,
legends for animation presented on the web. His approach allows the
viewer to interactively explore the data behind the map.
Finally,
in contrast to the emphasis by previous authors on data visualization,
Verbree and co-authors present an approach to design of virtual environments
in the context of infrastructure planning. They suggest that different
stages in a planning process require different views of the geographical
information in a virtual reality environment. These proposed views
are a plan view (the traditional 2d map), a model view (a 2d/3D symbolized
perspective image and the world view, and a fully immersive photorealistic
3d view on the data. All three views are dynamically linked, thus
actions applied to objects in one view have real time effects on associated
objects in other views.
