Title
2000 Digital Orthophotos, Twin Cities Metropolitan Area [Minnesota]
Description
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). More information at http://www.mngeo.state.mn.us/chouse/wms/geo_image_server.html , The digital orthophotos will be used for the 2000 Metropolitan Council land use interpretation project as well as for many other mapping and analysis functions. A note about zooming: The scale of the original photos (from which the digital data were created) was 1:40,000. Generally photogrammetrists suggest that the integrity of a photo image degrades noticeably after 5 times the negative scale (1:8,000 in this case), and that 10 times the negatives scale is the absolute maximum one should enlarge a photo (1:4,000)., The dates of the original aerial photography were May 1, 2000 (West Half of the metro) and May 2, 2000 (East Half of the metro).
