lEnumerators
account for all land usage in segment
Draw off field location by direct observation
Directly link questionnaire to segment photo
Able to ask questions not related to acreage
This is a sample of the questionnaire from
which the enumerator asks the farmer for information.
Enumerators record the growers responses on
cover type and acreage for each field in a segment on the JAS
questionnaire.The questionnaire is
directly linked to the NAPP 1:8,000 segment photo by referencing the field
number between the questionnaire and the photo. The JAS attribute data is
imported into RSP and used to compare the digitized acreages to the reported
acreages.The enumerator observations
are compared to the digitized acreage to filter out acreage discrepancies.
Performing segment digitizing during the JAS
allows the NASS State Statistical Offices to improve acreage estimates by
cleaning up acreage errors before the final official estimate is made.
The farmer reported data is only used internal
to NASS and cannot be derived from the public output Cropland Data
Layer.Farmer reported data is held
strictly confidential by NASS to calculate aggregated statistics.
