TatukGIS Viewer opens most GIS/CAD vector, raster image, and grid file types, including the aerial imagery and vector street map data provided by the leading vendors, most ArcView, ArcExplorer, and MapInfo projects, and projects exported from ArcGIS/ArcMap using the free Arc2TatukGIS plug-in.

Because the GIS Viewer is compiled from the TatukGIS Developer Kernel toolkit, it provides an easy way to evaluate the TatukGIS technology and support for various data formats and common GIS functionality.
The free Viewer can be used to generate TatukGIS project files that are compatible with any other TatukGIS product or custom applications created from the TatukGIS DK toolkit. The Viewer can generate simple ASP.NET projects for web publishing with the TatukGIS Internet Server.
The TatukGIS Editor product extends the free Viewer by adding an extensive set of features for editing, digitizing, merging, exporting, converting between formats, building/correcting map topological, etc. GIS shapefile map data.

TatukGIS Viewer Features:
1. Zooming in/out, panning on the map
