The following CD-ROMs are available for Mecklenburg County (call number Ref GIS Cabinet G3903 M6 A25 no. xx)
As of 2001, color digital orthophoto flights (flown at 1"=1300' scale, scanned to 1 foot pixel resolution) had been done (in 1999) and the data became available in May 2000. The raw data consists of about 705 individual TIFF images at 70 mb per image on 99 CD-ROMs. In 1997 black & white orthophotography was done (1 foot pixel resolution), resulting in 700 TIFF images at 23 mb per image on 33 CD-ROMs.
The Libraries do not currently own original TIFF versions of either the color or black & white raw data; however, MrSID mosaics of data from both flights are available. Data are in State Plane 1983/feet. Since the mosaics have been created using very high compression levels, the image quality is not as good as with the original images.
