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
... [More] Consortium
* JTS provides a complete, consistent, robust implementation of fundamental 2D spatial algorithms
* JTS is fast enough for production use
* JTS is written in 100% pure Java(
* JTS is open source (under the LGPL license) [Less]
SharpMap is an easy-to-use mapping library for use in web and desktop applications. It provides access to many types of GIS data, enables spatial querying of that data, and renders beautiful maps.
Hibernate Spatial is a generic extension to Hibernate for handling geographic data. It is generic in the sense that it works in the same way across different databases.
Hibernate Spatial allows
... [More] you to deal with geographic data in a standardized way, whatever database that you use (as long as a Spatial Dialect Provider exists for it). In other words, it abstracts away from the specific way your database supports geographic data, and provides a standardized, cross-database interface to geographic data storage and query functions.
Hibernate Spatial supports most of the functions of the OGC Simple Feature Specification. [Less]
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
... [More] reliable for any kind of .NET platform, PocketPC and SQL Server 2005 (through CLR integration) included. [Less]
MsSqlSpatial - Spatial Extensions for SQL Server 2005.
This project conforms to OGC Simple Features Specification for SQL Revision 1.1 and provides many useful features to power GIS applications.
The IMOS Ocean Portal is developed to meet the needs of the Australian Oceanographic community. In doing so it has developed a system for discovery and visualising spatial data via web protocols OGC WxS, CSW and OpenDAP
52°North Initiative for Geospatial Open Source Software GmbH is an international research and development company whose mission is to promote the conception, development and application of free open
... [More] source geo-software for research, education, training and practical use.
52°North backs an open initiative, which is driven by leading research organizations and individuals in the international GIS field.
Cooperation partners participate in research and development with focii on Sensor Web Enablement (SWE), Web Security and Geo-Rights Management , as well as Web Processing. [Less]
