This book is based upon the extensive practical experience of the authors
in designing and developing software tools for visualisation of spatially
referenced data and applying them in various problem domains. These
tools include methods for cartographic visualisation; non-spatial graphs;
devices for querying, search, and classification; and computer-enhanced
visual techniques. A common feature of all the tools is their high user interactivity, which is essential for exploratory data analysis. The tools can
be used conveniently in various combinations; their cooperative functioning is enabled by manifold coordination mechanisms.
