National Agricultural Imagery Program (NAIP) Digital Orthorectified Images (DOQ), Minnesota, 2003

This page last updated: 05/26/2009
Metadata created using Minnesota Geographic Metadata Guidelines


Metadata Summary

Originator U.S. Department of Agriculture, Farm Services Agency, Aerial Photography Field Office
Abstract This data set contains photographic information obtained for the National Agricultural Imagery Program (NAIP) and is comprised of scanned photographs that were acquired on color positive film. Acquisition was leaf-on with mature crops prior to harvest. Images have been orthorectified. NAIP imagery is quarter-quadrangle centered to provide consistent and repeatable coverage. The quarter-quad photos have been mosaicked into MrSID format county files.

(Note that the Farm Services Agency provided one metadata record per MrSID county file; the Land Management Information Center created this metadata record to describe the whole data set. For information that FSA did not provide, the metadata for Minnesota's NAIP 2002 imagery can serve as a general guide to the NAIP program procedure -- some of the specific processing steps or accuracy assessments may differ from the 2003 program: http://www.lmic.state.mn.us/chouse/metadata/naip02.html )

Title National Agricultural Imagery Program (NAIP) Digital Orthorectified Images (DOQ), Minnesota, 2003
Abstract This data set contains photographic information obtained for the National Agricultural Imagery Program (NAIP) and is comprised of scanned photographs that were acquired on color positive film. Acquisition was leaf-on with mature crops prior to harvest. Images have been orthorectified. NAIP imagery is quarter-quadrangle centered to provide consistent and repeatable coverage.

Purpose NAIP imagery serves as a base for Farm Service Center GIS applications and is used to administer USDA commodity support programs and conservation planning. The MrSID mosaics were compiled to provide a data format that is highly compressed (20:1) with minimal data loss.

Section 2 Data Quality Information Top of full metadata Top of page
Attribute Accuracy Color and tonal differences between the individual scanned images that were apparent in the interim version of the NAIP2003 data set have been largely corrected. Details about the procedure used are not available.
Logical Consistency N/A
Completeness Some parts of the state, primarily areas in Lake and Cook Counties, could not be photographed due to poor weather conditions.
