This dataset contains 267 black and white digital orthophoto quarter-quadrangles (DOQs), 3.75' x 3.75', covering the 7 county Twin Cities (Minneapolis and St. Paul) Metropolitan Area in Minnesota. Each CD-ROM contains up to 4 quarter-quadrangles of a USGS 7.5 minute quadrangle, where a quarter-quadrangle is included IF it's coverage includes any portion of the Twin cities 7 county area. The orthophotos are in UTM, Zone 15, NAD83 projection. Each image is approximately 115 Mb, with a .6 meter image pixel, and available in TIFF format. There are a total of 78 CD-ROMs. These orthophotos were produced using the USGS DOQ specifications except for the file format and the scan resolution (pixel size is .6m rather than 1 meter). The original imagery was collected at 20,000 ft. and centered on USGS quarter-quads. This dataset is available for direct use via the MnGeo Geospatial Image Service (Twin Cities metro layer).
