Hello,
I'm catching up late on the DOQQ thread. It's interesting to hear how other
libraries are approaching this. Here at NC State we initially acquired the
first 1200 tiles of the '93 black & white orthophotos for free from campus
units. We then purchased, in 1998, the remaining 2500 or so tiles from USGS
directly (BIL format) for about $20k. Prior to that we received the 'County
DOQQ' product (JPEG) on Depository 25 counties, before that program died.
Eventually our state Geologic Survey created the JPEG product for our remaining
75 counties and we bought that as well (only $8/county)--but the 'County' DOQQ's
were never popular because of the poor quality of the JPEG images and the odd
file naming and header scheme.
In 1999 we gained access to State Plane (feet & meters), JPEG, clipped versions
of the data (reprocessed from original BILs) for free from our state DOT in
trade for DOQQ's we bought and the state hadn't received. Because most people
work in State Plane/meters here (state standard projection) the State Plane
JPEGs are a bit more popular than the original UTM, BILS. We do MrSID
compressions of the BILs on a per request basis but, because: a) few of our
users work in UTM, b) border 'no data' areas in unclipped images prevent tiling,
and c) there are limits as to how MrSID imagery can be reprocessed in GIS/IP
software, we have no incentive to compress the BILs en masse. We also have
access to State Plane (feet & meters), MrSID county mosaics (freely downloadable
from our state DOT) and will be getting a State Plane/feet BMP images from a
commercial firm for free as part of a cooperative effort. I've been told we can
get UTM, MrSID county mosaics from the Forest Service but we're not as
interested in UTM mosaics. As for delivery, the State Plane JPEGs are served
from our Soils Dept. server and linked from the Libraries GIS pages. The BILs
are FTP by request or on CD (We only have 42 gb server space--ramping up to 350
gb or so this Spring. Access is Netware and IP-restricted FTP and HTTP).
The state did color infrared, one meter resolution flights in 1998-99 and we've
since received the eastern 1/3 of the state in State Plane 83/meters, clipped,
MrSID format (delivered to our state that way by USGS). The rest of the state
will be processed by mid-2002. This data we got for free as part of a
cooperative agreement with the state. We serve this data locally off our server
and it will eventually be freely downloadable from the state govt. We do not
yet have the original GeoTIFFs but we're hoping to work something out on that
(will be about 540 gb total).
We are also acquiring orthophotos from county governments. These are typically
six-inch resolution in developed areas, one foot in semi-developed, and two foot
in rural areas. About 70 of our 100 counties have or soon will have their own
orthophotos. The higher resolution and the addition of a time series piece make
these interesting to users. So far we've got orthos for about 20 counties, data
amounts ranging from 10 to 100 gb per county. We try to get the original,
uncompressed images but in a few cases have had to (so far) settle for receipt
of MrSID images.
Best regards,
Steve Morris
