ICREST Raster Dataset Listing and File Descriptions
IMPORTANT NOTE: Data on ICREST/MSDIS are being reorganized.
Raster data types (imagery data e.g. DOQQ, NAIP, DRG) are being migrated
to our sister
organization ICREST
The
new ICREST FTP server file
structure
is described below. Click a link for more detailed
description
of folder
contents.
Go to the MSDIS FTP server file structure (http://www.msdis.missouri.edu/pub).

http://www.msdis.missouri.edu/msdisdata/pub//dem/24k/county
<county name>.e00.gz - County level 1:24000 DEMs (Digital
Elevation Model) files available from MSDIS. Each file is a 30-meter
resolution ArcInfo lattice of a Missouri county with a 1000-meter buffer.

Here are the DRG (Digital Raster Graphic) files from the USGS. The directory
structure is organized by scale with subdirectories for files with the collars
clipped or not (Currently only the unclipped versions are available). A easier
graphical method to find DRGs is available HERE.
The DRGs have three (3) files associated with each instance. Be sure to download
the .tif (image), the .fgd.gz (metadata) and the .tfw (world) file. The world
file (.tfw) has been shifted to NAD83. Each directory contains the 24k DRGs
(filename prefix o). You will also find the associated 100k (filename prefix
f) and 250k (filename prefix c) DRGs here.
See the DRG Quad Sheet List page for
more info.
Be aware: If you use the .tif without the
.tfw you will be in NAD27. These are right off the USGS CD-ROMs.
The .tfw file is the only file we processed. The shifted .tfw file
puts the image into NAD83. The collar of the DRG will still say NAD27.
Collarless DRGs will be available in the near future.

<county name>.tar.gz - Mosaiced 100k USGS
DRGs for all Missouri counties.

<usgs gazeteer ref map name>_<state>refmapnumber>.tif.gz -
Compressed tif images of the pages from the USGS DRG gazeteer.
http://www.msdis.missouri.edu/msdisdata/pub//mrsid/doq
1:24,000 DOQ (Digital Ortho Quarterquad) files are available
from MSDIS. Each DOQ consists of three files, a MrSID file, a world
file and a text file. You must download all three to correctly
georeference the DOQ. The DOQ's are available at county level. Individual
quads available by request.
http://www.msdis.missouri.edu/msdisdata/pub//mrsid/doq/county/
<county name>.tar.gz - the DOQs for each county
are mosaiced together into 1 file with a 1000-meter buffer. All the
individual quads used to create the county wide files are available
in the quad subdirectory.
http://www.msdis.missouri.edu/msdisdata/pub//naip2003/
<short county name>.tar.gz - This directory
contains imagery data from the National Agricultural Imagery Program.
The NAIP 2003 imagery from the USDA is now available on MSDIS as
county-wide files in MrSID format, TARred and GZIPped. These are
near infrared aerial photography images.
NOTE: seven counties were originally projected in UTM Zone 16,
NOT Zone 15. These files have now been reprojected in UTM Zone 15.
