USGS Aerial Photography 1995-1998

The aerial imagery in this dataset are copies of standard digital orthophoto quarter quadrangles (DOQQ) received from the Natural Resource and Conservation Service which they obtained from the US Geological Survey. Dates range from approximately 1995 on the western side of the state thru 1998 on the eastern side of the state. An index containing dates is available in the QuadIndex dataset. Image acquisition scale: 1:40,000 (1"=3,333 feet); Map scale: Meets national map accuracy standards for the scale of 1:12,000 (1"=1000 feet); Accuracy: +/- 33.3 feet; Pixel size: 1 meter x 1 meter. DOQ images were acquired in native BSQ or TIFF format and either 1) left in UTM, NAD83, Zone 14 format, or 2) reprojected from UTM NAD83 Zone 13 to Zone 14 using ArcInfo Workstation vers. 8.2, 8.3, and 9.0; They were then clipped to USGS 3.75' quarter quadrangles before being mosaiced into state-wide image; Resampling for SDE pyramids was done using bilinear interpolation. The work was done June 2002 thru September 2004. Constraints: Not to be used for navigation, for informational purposes only. See full disclaimer for more information.
