With the upcoming release of ArcGIS 10.1 there is now support for the reading of .GRD (Grid) and .GRC (Classified Grid) raster files that are produced by MapInfo, Vertical Mapper and various telecom wireless planning tools. These files are usually used to represent the output of a signal strength prediction analysis for a given cell tower location. These raster’s are often converted to vector format on which various types of analysis are then performed.
This new format adds an extra dimension of analysis capabilities for our telecom users. This format can now be used like any other raster format with any of the core ArcGIS raster functions and the Spatial Analyst extension. The ArcGIS platform can now also be used to convert this data into its vector format for use within any existing vector based business work flows you may have.
We hope you enjoy this new feature with the coming ArcGIS release,
