A few words about NTS...
The main goal of this project is to have a .NET GIS solution that is
fast and reliable for any kind of .NET platform, PocketPC and Sql
Server 2005 (through CLR integration) included.
The project also includes some parts of another .NET library
GeoTools.NET, that integrates the capabilities of read/write data from
and to file formats such as Shapefile format, coordinate
transformations and projections, and much more.
NetTopologySuite, which is also hosted at GotDotNet, is intended as a
direct-port of all the functionalities offered by JTS Topology Suite
API: the main goal of the project is simply to expose JTS API in a
'.NET way' (as example using Properties, Indexers, etc.), but not to
add new functionality (for the moment...).
