The following is a list of county wide DOQQ (Digital Ortho Quarterquad) files available from MSDIS in MrSID format. Each county DOQQ consists of mosaiced MrSID images of the individual quads for each Missouri county with a 1000-meter buffer. The MrSID DOQQ, the world file and the text file have been zipped together into one file for faster download and you will need WinZip or a similar program to unzip it. You must download all three to correctly georeference the DOQQ.
Flight dates for all the quad level DOQ's are available HERE (Adobe pdf format, 199kb). The projection is UTM, NAD83, Zone 15.
Please see the GZIP Help Page if you run into trouble unzipping the files.
The directory location of these files is:ftp://msdis.missouri.edu/pub/Imagery_Base_Maps/doqq/county
