Naming Conventions:
City Files:
  • Files are named by the first 4 letters of the city. In cases where more than one city has the same first four letters, the first 3 and the 5th letter are used.
  • *.dgn (design file) extension denotes city maps 
  • *.bdr (border file) extension denotes the border file for each city.  These files are placed in the subdirectory called borders_citymap.
 
County Files:

  • File naming convention is based on the county name and the sheet number within that county. The county name is the first four letters of the county; the sheet number may be 1 through the number of sheets available for a given county. For example, the file name for sheet 2 of Crook County would be croo2.dgn.
  • *.dgn (design file) extension denotes county map design file
  • *.bdr (border file) extension denotes the border file for each county sheet.  These files are placed in the subdirectory called borders_comap.
 
County Map Series Notes:
  • This centerline series is arranged by county sheet number
  • The linework originated from USGS 1:100,000 dlgs.
  • The linework within urban enlargement frames on level 43 outline areas was digitized from 1:24,000 USGS quads (NAD 27). The 1:100,000 linework was then edge matched to the 1:24,000 linework at these frames. These enlargements are available in greater detail in the form of our urban enlargement series.
