Cannot display Digital Charts of the World coverages in ArcCatalog

Description

ArcCatalog does not display Digital Charts of the World (DCW) coverages.

Cause

DCW coverage data is stored in a pre-7.0 coverage format. ArcGIS Desktop does not support pre-7.0 coverages.

Solution or Workaround

• In ArcInfo Workstation, use the CONVERTWORKSPACE command, which allows a pre-7.0 workspace to be converted to a 7.0 workspace and converts the coverages it contains to the new format.
  

  Code:
  CONVERTWORKSPACE <PRE-7.0 | NEW> {workspace}

  
  Arguments
  
  < PRE-7.0 | NEW> - specifies the output file naming convention.
  
  PRE-7.0 - converts to the pre-Version 7 workspace file name format.
  
  NEW - converts to the new Version 7 workspace file name format.
  
  {workspace} - specifies the workspace to be converted. The default is the current directory.
• In ArcView GIS 3.x, display the coverage features, click Theme > Convert to Shapefile to convert each coverage feature class into a shapefile. The output shapefile can be used in ArcGIS Desktop.
