Do you know and use some tools to simplify your geographical data?
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.
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.
