about NetTopologySuite

website:
http://nts.sourceforge.net/

NetTopologySuite is a C#/.NET port of JTS Topology Suite, a Java library for GIS operations, (OpenGIS compliant).

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 SharpMap, 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...).

评：
1. NetTopologySuit，NTS是在研究JTS的基础上，转换成.net way的迁移平台。目前的目的只是实现jts的功能。
2. NTS和sharpmap相互利用了一些技术。
3. nts ,sharpmap, mssqlspatial等一些open source应该合作，集成。
4. nts充分利用了clr和sql server205.
5. nts应该会超过jts，无论是从性能还是应用，无论是研究还是商业价值。
6. nts为其他平台提供了很好的空间分析底层技术。
7. nts将成为.net platform上，open source gis的核心技术。
