Area-Normalized Thematic Views

of International Cartography Assembly, August 1999.
- Abstract:
- Thematic variables are commonly used to encode additional
information such as population density within the spatial layout of a
map. Such "themes" are typically encoded using colour-maps. We will
explore techniques for using this thematic information to directly
define spatial transformations so that areas of map regions are
proportional to their thematic variables, thus making the view more
consistent with the thematic encodings. Our method emphasizes
interactivity as a primary mechanism for allowing the user to better
realize the distribution of the thematic variable, rather than relying
on static views of the map.
