I am looking for existing solutions (softwares, libraries, methods, etc.) to automate the generalisation/simplification of geographical data as presented there, and also there.

How do you proceed when you need to simplify your geographical data? Do you know and use some tools related to this topic? What is your opinion on these tools?

I already had a look at these ones:

• maptimize to simplify the representation of KML marker layers,
• Modelbuilder by ESRI
• Radius clarity by laserscan
• mapshaper to compute online filtering algorithms on geometries,
• Axpand by axes-systems

The ICA commission on generalisation and multiple representation website is a huge information source on this topic. Many papers presents advanced methods and use cases related to this topic.

EDIT: the very famous douglass & peucker filtering algorithm is often used for geometrical simplification and is present in almost all GIS softwares. However, its effect is to make geometries very bony/angular without really simplifying the geometry shape. For example, it is not very adapted for lines representing roads or rivers, that have to be smooth and not angular.
