geocoding - Does anyone use TRS (Township, Range, Section) data?


I recently had a request for TRS/PLSS data and I didn't know anything about it. I have researched it and it looks like it is purely mathematical (for the most part) based on geo-coordinates but I'm wondering if anyone would actually benefit from this information.


For example, in our address verification service, we could provide the TRS data as well as the lat/lon data for each address.


Im wondering what industries actually use the TRS/PLSS data scheme.




Answer



The primary industry that uses this is the real estate industry, and planning and government. The TRS system is the basis for the legal descriptions that describe the locations of land parcels in most of the United States.


Legal Description - Wikipedia


There are a number of ways that the bounds of a land parcel may be described, but at some point, whether at the parcel level, or subdivision level, it is tied back into the TRS system. The caveat to this is that it mostly applies to land west of the Mississippi aside from Texas, the states bordering the Great Lakes, and the southern states aside from Georgia.


There are likely other uses, but I think this is the primary, and most critical in the context of property ownership rights in the US.
