The main goal of this project is to have a .NET GIS solution that is fast and reliable for the .NET platform. NetTopologySuite is a direct-port of all the functionalities offered by JTS Topology Suite: NTS expose JTS in a '.NET way', as example using Properties, Indexers, etc...

An excerpt from JTS website (http://sourceforge.net/projects/jts-topo-suite) explains the capabilities of NTS: "The JTS Topology Suite is an API for modelling and manipulating 2-dimensional linear geometry. It provides numerous geometric predicates and functions. JTS conforms to the Simple Features Specification for SQL published by the Open GIS Consortium."

Actually there are two versions of NTS:

• NTS v1.X: is the JTS-like version of the library. You can download the latest release in the "download" section or grab the latest sources in the trunk (http://nettopologysuite.googlecode.com/svn/trunk). The latest released version is NTS 1.11, that matches functionalities of JTS 1.11, and that can be found in the 'download' section.

• NTS v2.X: is a stable and powerful rewrite of the library, with many changes. You can grab the latest sources in the branches (http://nettopologysuite.googlecode.com/svn/branches/v2.11_cleanup), that matches JTS 1.11.

Both versions are stable enough to be used in production code, and maintained by the community, so you are invited to enjoy using them!

NuGet

If you're developing with Visual Studio 2010, you can grab NTS v1.X also using NuGet!. You can found the packages here: http://www.nuget.org/List/Packages/NetTopologySuite
