Free and Open Source GIS Mapping Software Program Applications

I have added some new open source and freeware GIS software programs. Here's a listing of some of the GIS applications included:

Geocoding - Map Channels offers free single address and batch geocoding.

GEODAS (GEOphysical DAta System) data management system can be run in Microsoft Windows, UNIX Xwindows and Macintosh OS-X environments. GEODAS software accesses all GEODAS Databases, including Marine Trackline Geophysics, NOS Hydrographic Surveys, Coastal Relief Model, ETOPO2 Gridded Elevations and Great Lakes Bathymetry DVD sets.

Geodetic software developed by the National Geodetic Survey (NCS). Free downloads - dozens of programs.

Geographic Foundation Class (GFC)Library is a set of C++ classes defining basic geographic data types, including points, lines, rectangles, circles, polylines, rings, complex polygons, rasters, and other atomic data types such as integer, real, varchar. GFC also features abstractions of timestamps and time series which are useful in capturing the dynamics of spatiotemporal data.

Geopublisher Software allows you to quickly create digital multimedia atlases and publish them. Visit the demo atlases page to take a look at some publically available atlases or check out the features list to get an impression about the possibilities.

GeoServer - GeoServer is an Open Source server that connects your information to the Geospatial Web. You can publish and edit data using open standards. Your information is made available in a large variety of formats as maps/images or actual geospatial data.

Geospatial Explorer has been written to enable geologists, environmental scientists, and engineers to apply innovative science and technology to enhance and expedite the reduction of risk to human health and the environment. Geospatial Explorer permits the user to identify, understand, and solve complex environmental problems better, faster, and cheaper.

Geographic Translator (GEOTRANS) is an application program which allows users to easily convert geographic coordinates among a wide variety of coordinate systems, map projections, and datums. GEOTRANS runs in both Microsoft Windows (95/98/NT) and UNIX Motif environments.

geos (Geometry Engine Open Source (GEOS)) is 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 functions such as IsValid().

GeoTools is Java code library which provides standards compliant methods for the manipulation of geospatial data, for example to implement Geographic Information Systems. The GeoTools library implements OGC specifications as they are developed, in close collaboration with the GeoAPI and GeoWidgets projects.

GeoVISTA Studio is an open software development environment designed for geospatial data. Studio is a programming-free environment that allows users to quickly build applications for geocomputation and geographic visualization.
