MB-System

MB-System is an open source software package for the processing and display of bathymetry and backscatter imagery data derived from multibeam, interferometry, and sidescan sonars. The source code for MB-System is freely available (for free) by anonymous ftp (including "point and click" access through these web pages). A complete description is provided in web pages accessed through links below.

MB-System was originally developed at the Lamont-Doherty Earth Observatory of Columbia University (L-DEO) and is now a collaborative effort between the Monterey Bay Aquarium Research Institute (MBARI) and L-DEO. The National Science Foundation has provided the primary support for MB-System development since 1993. The Packard Foundation has provided significant support through MBARI since 1998. Additional support has derived from SeaBeam Instruments (1994-1997), NOAA (2002-2004), and others.

AtlasStyler

AtlasStyler is a user-friendly application to style geodata. The resulting styles can be saved to XML files that follow the OGC SLD/SE standard 1.0. The AtlasStyler is a "stand-alone" application, that can be used independently for any vector data. ESRI Shapefiles, OGC WFS and PostGIS datasources are supported. Automatic upload of the SLD styles to Geoserver will be possible soon.

Geopublisher

Geopublisher is an atlas authoring system which enables easy publication of geo-data, documents, images, videos, and statistics in form of digital multimedia atlases. These atlases are effectively a minimal, pre-configured, end-user GIS which offers selected functionality only where its meaningful.

Geopublisher provides tools for quality assurance and multilingual meta-data management. No in-depth knowledge of HTML, SLD or XML is required to create an atlas. Atlases can be directly published on CD, DVD, memory stick, external hard-drive or the Internet. The software is platform-independent.

Geopublisher’s unique features make it especially applicable in the fields of international research, participatory GIS, capacity building, and development cooperation.

SAGA

SAGA (System for Automated Geoscientific Analyses) is an open source geographic information system (GIS) used for editing and analysing spatial data. It includes a large number of modules for the analysis of vector (point, line and polygon), table, grid and image data. Among others the package includes modules for geostatistics, image classification, projections, simulation of dynamic processes (hydrology, landscape development) and terrain analysis. The functionality can be accessed through a GUI, the command line or by using the C++ API.

SAGA has been in development since 2001, and the centre of SAGA development is located in the Institute of Geography at the University of Hamburg, with contributions from the growing world wide community.

Kosmo Desktop

The Kosmo project is the first Free GIS Corporative Platform, distributed under the GNU/GPL.
This project incorporates and does an intensive use of all the tools needed to satisfy the most of the users needs, so it implements:

• Kosmo Server: Raster and vectorial cartography server
• Kosmo Desktop: desktop GIS with powerful query, edition and analysis tools
• Kosmo Web Client: cartographic browser for connection with services based on OGC standards
• Kosmo Mobile: GIS software for mobile devices

Kosmo design and architecture is focused on management and analysis of territorial information through Spatial Data Bases, so providing it with corporative nature.
The project is in full development and with the first of its components -Kosmo Desktop- in continuous evolution and available for whom requires advanced functionality in an powerful desktop GIS.
It is worth to point that Kosmo is deployed in a vast number of productive systems with high requirements of both stability and functionality.

uDig ( User-friendly Desktop Internet GIS )

The goal of uDig is to provide a complete Java solution for desktop GIS data access, editing, and viewing. uDig aims to be:

• User friendly, providing a familiar graphical environment for GIS users;
• Desktop located, running as a thick client, natively on Windows, Mac OS/X and Linux;
• Internet oriented, consuming standard (WMS, WFS, WCS) and de facto (GeoRSS, KML, tiles) geospatial web services; and,
• GIS ready, providing the framework on which complex analytical capabilities can be built, and gradually subsuming those capabilities into the main application.

gvSIG

gvSIG is a Geographic Information System (GIS), that is, a desktop application designed for capturing, storing, handling, analyzing and deploying any kind of referenced geographic information in order to solve complex management and planning problems. gvSIG is known for having a user-friendly interface, being able to access the most common formats, both vector and raster ones. It features a wide range of tools for working with geographic-like information (query tools, layout creation, geoprocessing, networks, etc.), which turns gvSIG into the ideal tool for users working in the land realm.

GRASS (Geographic Resources Analysis Support System)

GRASS (Geographic Resources Analysis Support System) is a raster/vector GIS, image processing system, and graphics production system. GRASS contains over 350 programs and tools to render maps and images on monitor and paper; manipulate raster, vector, and sites data; process multi spectral image data; and create, manage, and store spatial data. GRASS uses both an intuitive windows interface as well as command line syntax for ease of operations. GRASS can interface with commercial printers, plotters, digitizers, and databases to develop new data as well as manage existing data.
GRASS and network support for teams
GRASS supports workgroups through its LOCATION/MAPSET concept which can be set up to share data over NFS (Network File System). Keeping LOCATIONs with their underlying MAPSETs on a central server, a team can simultaneously work in the same project database.
