•This is a sample of the questionnaire from which the enumerator asks the farmer for information.
•Enumerators record the grower’s 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.
