Free US Township and Range Data download

A little know secret is that Free Township Range data for each State can be had via the delorme Xmap site. Simply jump to and scroll down to the supplementary data section. NGS Benchmarks are also available for purchase for a very small fee.
The PLSS layer includes the following attributes for each section polygon:
  • TWP – Township number
  • TWP_DIR – Township direction, usually N (north) or S (south) of the survey baseline
  • RNG – Range number
  • RNG_DIR – Range direction, usually E (east) or W (west) of the principal meridian
  • SEC – Section number
