GEOS (Geometry Engine - Open Source) is a C++ port of the Java Topology Suite (JTS). As such, it aims to contain the complete functionality of JTS in C++. This includes all the OpenGIS "Simple Features for SQL" spatial predicate functions and spatial operators, as well as specific JTS topology functions such as IsValid().
The JTS Topology Suite is an API of 2D spatial predicates and functions. It has the following design goals: * JTS conforms to the Simple Features Specification for SQL published by the Open GIS Consortium * JTS provides a complete, consistent, robust implementation of fundamental 2D spatial ...

A port of JTS to .Net, rewritten to take advantage of CLR constructs, as well as remove some of the legacy issues in JTS.
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.
GeoKettle is a powerful, metadata-driven spatial ETL (Extract, Transform and Load) tool dedicated to the integration of different data sources for building and updating geospatial databases, data warehouses and services. It is based on Pentaho Data Integration (Kettle).
OrbisGIS is a Geographic Information System developped for and by research. . This cross-platform GIS is developed by French IRSTV institute and is able to manipulate and create vectorial and raster spatial data. OrbisGIS is distributed under GPL 3 license.
This project is a collection of tools for use with the spatial types that are new to SQL Server 2008. This project does not provide an end-user application, but rather a set of reusable functions which applications can make use of. These functions may include data conversion routines, new ... [More]
