Each year three sets of sample files are distributed to States for the NRI Grazing Land On-site Survey. They include:
- The number of sample segments by county
- The list of sample segments
- Point-level information for the sample
The point-level file includes the most recent year the point was observed in the photo-interpreted (PI) NRI appended to the land cover/use (LCU) code recorded during that observation. Any point observed in PI after 2004 will have a current annual NRI land cover use (LCU) code, which may be slightly different from the NRI grazing lands LCU as NRI grazing lands still uses the pre-2005 LCU codes. The following tables provide both the pre-2005 codes and the corresponding post-2005 land cover/use organized by Pre-2005 Annual NRI General LCU.
The source of this information is section 3.4.1 of the 2016 NRI Collection Instructions.
