DRG Index

The USGS Topographic Map tile indices can be used to determine the 7.5 minute, 1:24,000 scale map boundaries for Utah.

Each tile index contains the following attribute fields:

  • Name - the name of the map
  • OHIO_CODE - code usded by USGS
  • TILE - the image tile name on FTP site
  • PATH - the directory where the topographic map tile resides on the FTP site

The native spatial reference for this dataset is UTM Zone 12N, NAD83 (0.01 meter coordinate precision). There are no constraints or warranties with regard to the use of this dataset. Users are encouraged to attribute content to: State of Utah, SGID.
