Project Detail - Digital Preservation (Library of Congress). The GeoMAPP project is exploring ways to expand the capabilities of state governments to provide long-term access to geospatial data. The project is bringing together geospatial and archival staff in multiple states to identify, preserve, and make available temporal and superseded digital geospatial data with ongoing value. A key approach will include testing a geographically dispersed content-exchange network for the replication of state and local geospatial data among several states to promote preservation and access.
The Open Geospatial Consortium, Inc.® (OGC) is a non-profit, international, voluntary consensus standards organization that is leading the development of standards for geospatial and location based services.
OpenLayers is a pure JavaScript library for displaying map data in most modern web browsers, with no server-side dependencies. OpenLayers implements a (still-developing) JavaScript API for building rich web-based geographic applications, similar to the Go
ZDNet's Dana Blankenhorn reports today on a new open source navigation project launched by European GPS company TomTom that adds additional functionality to navigational devices, regardless of the make or model. The OpenLR project aims to put navigation data on top of a GPS unit's existing database so drivers can access local traffic, weather, and other useful information as they travel.
After installing ArcGIS Server, there are a few things you need to do before you can start creating services and allowing client applications to access these services. The steps below provide a summary of the things you need to think about and do to get s
Open Source programs are applications of which you can access the source code. Listed here are available open source GIS-based applications you can download written for a variety of platforms and in various languages.
Commonly referred to as GRASS, this is free Geographic Information System (GIS) software used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies. GRASS is an official project of the Open Source Geospatial Foundation.
ESRI's GIS (geographic information systems) mapping software helps you understand and visualize data to make decisions based on the best information and analysis.
Opticks is an expandable remote sensing and imagery analysis software platform that is free and open source. If you've used other commercial tools like: ERDAS IMAGINE, RemoteView, ENVI, or SOCET GXP, then you need to give Opticks a try. Unlike other competing tools, you can add capability to Opticks by creating an extension. Opticks provides the most advanced extension capability of any other remote sensing tool on the market.
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

CartoWeb is a comprehensive and ready-to-use Web-GIS (Geographical Information System) as well as a convenient framework for building advanced and customized applications.
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.
