Libraries

• GRASS:
  • libgrass: Standalone GRASS 5 I/O Library to directly read/write GRASS Databases. [Outdated!]
    Recommended: GRASS/GDAL plugin (here). Example usage: MapServer is able to read GRASS locations directly.
    Visit the GRASS/MapServer Demo site!
• PROJ 4: Projection/datum support library. It also provides the 'cs2cs' software which reprojects x,y [,z] coordinate lists including datum transformation.
• GDAL: Geospatial Data Abstraction Library (raster)
• OGR: OGR Simple Features Library (vector)
• GRASS XML pages for XML (Extensible Markup Language) support

Other projects

• FreeGIS: Link collection of Free Software for geographic information processing and data sources with similiar freedoms.
• Thuban: Stable crossplatform interactive geographic data viewer. Supports raster (via Gdal), vector and PostGIS data. Extensible, can do projections (via proj), manage and query attribute tables.
• QGIS data Viewer: Supports raster, vector and PostGIS data, GRASS 5.7 support is under development
• Vector:
  • Skencil Free Software drawing tool which also can read xfig format. There is an add-on to read shape files. The upcoming 0.7 will directly read Skencil-map-SVG files created by Thuban.
  • Xfig: a nice Free Software (map) drawing tool. GRASS offers v.out.xfig to export vector data in xfig format. Raster data can be imported as TIFF.
  • LX-Viewer (GPL, LX-Viewer is a program that will allow you to open, view and print DWG or DXF files. Note that LX-Viewer depends on a non-free library.)
• Webmapping: UMN MapServer
• Image processing: OSSIM: Open Source Software Image Map project
• Viewer: OpenEV: OpenEV is a library, and reference application for viewing and analysing raster and vector geospatial data.
• Viewer: Vis5D Visualization - See Vis5D+ page as well
• PostgreSQL DBMS - PostGIS
• (outdated) LTPlus (Line Trace Plus) (Line digitizer program) - see as well ltplus.org (Note: The status of its license might still need clarification.)
