CDV: Cartographic Data Visualization

The CDV-TS system combines visualization and dynamic cartography techniques in order to explore data on routes of individuals in a spatial lattice. The routes are qualified by the segments and points of a network borrowed in course of time and also connected to a qualitative data base on the individuals making the routes. The CDV-TS system allows to analyse the use of space, the temporal distributions and the contexts of the space-time behaviours.
The software CDV-TS has been developed by Jason Dykes and Wim G.M. van der Knaap. Jason Dykes, who developed a display system of the space data called CDV (with an interface in Tcl Tk), made modifications in order to allow a simultaneously exploration of geographical data (points, lines, polygons) connected to space-time data.

Comments During the launching of the program, 4 principal windows appear: the window "attributes" which makes it possible to select certain qualitative characteristics of the individuals of the population concerned; the window "cartography" which makes it possible to choose the way in which the routes will be represented; the window "map" which makes it possible to visualize the routes in the network of the analyzed population; the window "time" which makes it possible to make a temporal request on the routes.
