See presentation in attachment related to selection of a map control for DelftShell.
The final choice is SharpMap v0.9 for now and v2.0 in a longer term, including all related libraries such as:
- GeoAPI.NET - OGC compliant interfaces
- NetTopologySuite - implementation SFS Geometries defined in GeoAPI
- NPack - math
- Proj.NET - implementation of the OGC coortinate reference systems
Also ArcGIS implementation will be created somewhere in the future.
It looks like it has sufficient functionality to implement various schematization editors and visualization of results on a map.
