How To: Convert GeoDatabase to single precision coverage in Desktop ArcInfo


The ArcToolbox Geodatabase to Coverage tool creates a single precision coverage even though the input is a double precision coverage. These steps will allow you to maintain the original double precision coordinates.


  1. Use the ArcToolbox GeoDatabase to Shapefile tool to create a shapefile.
  2. Use the Arc PRECISION command to set the precision environment to DOUBLE DOUBLE.
  3. Use the Arc SHAPEARC command to create a double precision coverage.
