Quantum GIS

Quantum GIS (QGIS) is an Open Source Geographic Information System (GIS) that runs on GNU/Linux, Unix, Mac OSX, MS Windows and Android. QGIS supports vector, raster, and database formats and is licensed under the GNU General Public License.  Supported formats include a wide variety of vector and raster data types, including ESRI shapefiles, spatial data in PostgreSQL/PostGIS, GRASS vectors and rasters, and GeoTiff.  QGIS can be customized through plugins and GIS enabled applications written in Python or C++.   Resources:  Home Page | Forum | Blog | Tutorials

Google Fusion Tables

Though not a GIS, Google Fusion Tables provide a cloud based mechanism to upload, store and manage spatially referenced data and present the data in Google Maps in minutes, and for free.  Fusion Tables store points, lines and polygons as KML features and supports associated attribute information including links and photos.  The info window is customizable allowing for formatted display of attributes, image sizing, etc.  Data access can be controlled within the Fusion Table environment allowing for collaborative editing, or locked down for private use.  For more information the Google Fusion Website.  Click here to view the North Carolina Google Fusion fish attractor example highlighed in the Spring 2012 Newletter or here to view the Georgia DNR Boating Access Map, also running on Google Fusion Tables.

ET Spatial Techniques

Ever wish you had an ESRI ArcInfo license to perform a task or function more efficiently than your ArcView license will allow?   Well, ET Spatial Techniques for ArcGIS may provide a solution.  ET Spatial Techniques offers a series a freely downloadable tools (e.g.. ET Geowizards, ET GeoTools, etc.), with certain functions restricted unless you purchase.  That said, the unrestricted tools are very useful and the website is worth a visit. Resources:  Home Page.
