PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS "spatially enables" the PostgreSQL server, allowing it to be used as a backend spatial database for geographic information systems (GIS).
geopy makes it easy for developers to locate the coordinates of addresses, cities, countries, and landmarks across the globe using third-party geocoders and other sources of data, such as wikis.
POLYMAP koppelt unterschiedliche Geo- und Fachinformationssysteme (GIS) und bringt deren Daten in den Web-Browser. POLYMAP ist vollständig in Java geschrieben und wird unter einer Open-Source-Lizenz entwickelt.
polymap.org bietet den Rahmen für Diskussion, Weiterentwicklung und Pflege des Basissystems und der Plugins. Plugins erweitern das System um praktisch beliebige Funktionen und bauen aufeinander auf. Plugins können von jedem entwickelt werden und sind nicht zwingend Open-Source
The purpose of the Data Preservation WG is to provide a venue and mechanism for seeking technical and institutional solutions to the challenge of preserving digital geospatial data.
