GeoTools
GeoTools is an open source (LGPL) Java code library which provides standards compliant methods for the manipulation of geospatial provides standards compliant methods for the manipulation of geospatial data, for example to implement Geographic Information Systems (GIS) . The Geo Tools library implements Open Geospatial Consortium (OGC) specifications as they are developed, in close collaboration with the GeoAPI and GeoWidgets projects.

GeoServer
GeoServer is an open source server that connects your information to the Geospatial Web. GeoServer allows to publish and to edit data to the Geospatial Web. GeoServer allows to publish and to edit data using open standards. The information is made available in a large variety of formats as maps/images or actual geospatial data. GeoServers transactional capabilities offer robust support for shared editing. GeoServer supports WFS-T and WMS open protocols from the OGC to produce JPEG, PNG, SVG, KML/KMZ, GML, PDF, Shapefiles and more. GeoServer is built on Geotools.

GeoNetwork
GeoNetwork opensource is a standardized and decentralized spatial information management environment, designed to enable access to information management environment, designed to enable access to geo-referenced databases, cartographic products and related metadata from a variety of sources, enhancing the spatial information exchange and sharing between organizations and their audience, using the capacities of the internet. This approach of geographic information management aims at facilitating a wide community of spatial information users to have easy and timely access to available spatial data and to existing thematic maps that might support informed decision making.

uDig
The User-friendly Desktop Internet GIS (uDig) is both a GeoSpatial application and a platform through which developers can GeoSpatial application and a platform through which developers can create new, derived applications. uDig is a core element in an internet aware Geographic Information System. uDig has been developed with a strong emphasis on supporting the public standards being developed by the Open Geospatial Consortium, and with a special focus on the Web Map Server and Web Feature Server standards.

GeOxygene
GeOxygene aims at providing an open framework which implements OGC (Open Geospatial Consortium) specifications and ISO standards for OGC (Open Geospatial Consortium) specifications and ISO standards for the development and deployment of geographic (GIS) applications. It is an open source contribution of the COGIT laboratory at the IGN (Institut Geographique National), the French National Mapping Agency. It provides users with an extensible object data model (geographic features, geometry, topology and metadata) which implements OGC specifications and ISO standards in the geographic information domain. Data are stored in a relational DBMS (RDBMS) to ensure a rapid and reliable access to the system but users do not have to worry about any SQL statements: they model their applications in UML and code in Java. Mapping between object and relational environments is performed with open source software. At present, OJB is supported and the mapping files for the storage of geographic information in Oracle or PostGIS are provided to users.

OpenJUMP
OpenJUMP is an open source GIS software. It is based on JUMP GIS by Vivid Solutions. Features: by Vivid Solutions. Features: * OpenJUMP is a Vector GIS that can read rasters as well. * OpenJUMP is a Vector GIS that can read rasters as well. * OpenJUMP works, even with medium size datasets, and with professional touch. * OpenJUMP provides a GIS API with a flexible plugin structure, so that new features are relatively easy to develop around the sound mapping platform. * OpenJUMP utilizes standards like GML, WMS and WFS. * OpenJUMP supports a couple of languages (English, Finnish, French, German, Portuguese and Spanish).

gvSIG
gvSIG is a tool oriented to manage geographic information. It is characterized by a user-friendly interface, with a quick access to the characterized by a user-friendly interface, with a quick access to the most usual raster and vector formats. In the same view it includes local as well as remote data through a WMS, WCS or WFS source.

GeoGoogle - Free Address Standardizer
Java address standardization API that utilizes googles geocoding service. It parses an input address, sends it to google geocode service service. It parses an input address, sends it to google geocode service via http and then parses the return result into an address object. You get a free geocoding service thanks to google.

JGeoCoder - Free Java GeoCoder
Geocoding is the process of estimating a latitude and longitude for a given location. JGeocoder is a free geocoder implemented in Java. for a given location. JGeocoder is a free geocoder implemented in Java. This project is loosely modeled after Geo::Coder::US , a Perl module available for download from the CPAN.
