Widely appreciated as the world’s best free desktop GIS Viewer, this application natively opens (without any import procedure) just about any GIS vector, image, or geodatabase data type ranging from ESRI SHP files to MrSID compressed imagery to the most advanced spatial database map layers. WMS and WFS layers and Web Map Tiles can be opened from the web. Comprehensive visual layer property, legend, and scale controls provide for deep customization of the appearance of each map layer, thematic mapping, layer hierarchies, legend presentation… which can be saved as a multi-layer project file. The data grid table displays attribute data for analysis and querying. State-of-the-art support for coordinate systems includes 3,000 predefined coordinate systems and on-the-fly vector/raster layer reprojection. While a highly useful product in itself, the Viewer is a free demo for the more powerful TatukGIS Editor product and an excellent example of an application developed/compiled from the TatukGIS Developer Kernel (SDK).
Itís holiday time and that means itís time for Santa Trackers from the likes of North American Aerospace Defense Command (NORAD) and Google. At one time a small footnote to the season, this yearís trackers host games, fighter jets and somewhere in there, a bit of education for children and adults. What can the Santa Trackers teach us?
