TNTAtlas 2013, Shapefile Viewer for Mac OS X
The shapefile, is a popular geospatial vector data format for geographic information system software developed by Esri. Shapefiles stored non-topological vector data geometric location and associated attribute information.
A shapefile is actually a set of several files, at least three basic files: .shp, .shx and .dbf. All three files must be present in the same directory for them to be viewable. The actual shapefile relates specifically to .shp files but alone is incomplete for distribution, as the other supporting files are required.
Esri’s ArcGIS Explorer Desktop is the most popular desktop shapefile viewer. The software can be downloaded for free and integrates with ArcGIS Online. ArcGIS Explorer only works on Windows OS environments.
