Beijing, China (PressExposure) April 22, 2008 -- The free AvisMap Viewer opens most GIS/CAD and raster image file types and most ArcView, ArcExplorer, and MapInfo projects. Besides just opening and viewing files, the Viewer supports an extensive list of features including visual layer properties control, legend control, thematic mapping, spatial and attribute querying, custom labeling, on-map measurements, hyper-linking, PDF export and much more.
Because the GIS Viewer is compiled from the AvisMap Map Engine, it provides an easy way to evaluate the AvisMap technology and support for various data formats and common GIS functionality. The free Viewer can be used to generate AvisMap project files that are compatible with any other AvisMap product or custom applications created from the AvisMap GIS Engine.
The AvisMap Desktop product extends the free Viewer by adding an extensive set of features for editing, digitizing, merging, exporting, converting (between formats), building/correcting map topology, etc. GIS shapefile map data.
