Public Land Survey Data

Public Land Survey System Land Grid Data

Our Public Land Survey is a seamless, high-resolution database of Congressional Survey townships and sections that is ideal for base maps and plotting land ownership and leases. Public Land Survey is offered as either USGS PLSS digitized from USGS 1:24,000 series topographic maps, or BLM CAD NSDI PLSS land grid format.  For the USGS derived product, DDS used a highly accurate spatial averaging digitizing technique, which captures corner boundaries to +/- 40 foot accuracies. Land grid matches the USGS 1:24,000 scale topo maps pricesly.
