eUSGS DOQQ Data

Ranges from 1995 to 1998 and represents a number of updates

Lat/long folders contain .bsq and .hdr files and also some contain folders containing quad name files.  Note that these were derived from original .zip files.  During unzipping, the following zips had issues and therefore these .bsq files are not present:  48101d1_4 -> empty zip; 48097a6_2 -> CRC; 48101d2_4 -> CRC

Lat/long folders ending in _updated reflect updated files. Where there is apparent duplication between the files in _update and in those folders NOT ending in _updated, it appears that the two datasets represent different times of years

Statewide_GeoTiffs contains GeoTiffs originally loaded into SDE and likely produced by a state agency apparently using .bsq data as input.  Note that when comparing these files to what was in SDE, at the boundary of some of these files there are gaps/slivers.  I.e., both the GeoTiffs and what was in SDE both reflect gaps and slivers.  This then is carried through in the image service.
