DLGV 32 Viewer

The dlgv32 viewer is a free downloadable software provided by the footer image. USGS Mid-Continent Mapping Center (MCMC). The dlgv32 viewer is designed to preview cartographic data sets, such as DLG, DRG, DEM, and DOQ. The viewer allows you to merge and layer the data files.

The dlgv32 is a data viewer program designed to preview the following cartographic data sets:

  1. Digital Line Graph optional format (DLG-O)
  2. Digital Line Graph SDTS (DLG/SDTS)
  3. GeoTIFF Digital Raster Graphic (DRG)
  4. GeoTIFF Digital Orthophoto Quadrangle (DOQ)
  5. GeoTIFF USGS Digital Elevation Model (DEM)
  6. Native format USGS Digital Elevation Model (DEM)
  7. GTOPO30 Digital Elevation Model (GTOPO30)
  8. Terrain Base Digital Elevation Model
  9. Digital Elevation Model SDTS (DEM/SDTS)
  10. Native keyword format USGS Digital Orthophoto Quadrangle (DOQ)

The dlgv32 viewer runs on Windows platform. Click on the following links to download the desired version of the dlgv32 viewer.

Dlgv32 version 5.10
