ScapeToad: not just one metric
Most 2D-maps are used to represent topographic metrics: distances and areas measured on the map (multiplied by the map scale) give traveling distances and land surfaces. In some cases, this information is irrelevant or even misleading [see an example]. As a cartographer, you may wish to use map metrics to represent other data, such as human populations or amounts of produced resources. This is what ScapeToad is for.
How does it work?
ScapeToad uses the Gastner/Newman  diffusion-based algorithm to adapt map surfaces to user-defined variables without altering their topological relations.
How and where can it be used?
ScapeToad also exports maps in SVG format.
ScapeToad has a user-friendly interface, which guides the user throughout the map creation process.
Where can I get ScapeToad?
ScapeToad is available from our download page since April 21st 2008.
