Metadata created using Minnesota Geographic Metadata Guidelines
| 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. 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.

| 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. | |||
| Time Period of Content Date | 2003 | |||
| Currentness Reference | Summer 2003. FSA's metadata records for each county MrSID file contain the date that each original quarter quad photo was flown. | |||

| 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. For a list of the missing quarter-quadrangles see: http://www.lmic.state.mn.us/chouse/naip03notflown_list.html For a map showing the location of the missing quarter-quadrangles, see: http://www.lmic.state.mn.us/chouse/naip03flown_map.html |
