- Abstract:
-
The U.S. Geological Survey's Upper Midwest
Environmental Sciences Center (UMESC) has obtained
historical photography of the Upper Mississippi
River, collected by the Corps of Engineers in the
1930s. The Center uses these photos in their
training program for GIS interns, to provide them
with experience in georeferencing photos.
Whenever enough photos are georeferenced that a
mosaic can be created, the data are made available
through the center's Internet site. The 1937
photo mosaic for Mississippi River Navigation Pool
15 was created using 1:20,000-scale
black-and-white photos collected during September
1937.
- Purpose:
-
The Upper Midwest Environmental Sciences Center
administers the Long Term Resource Monitoring
Program (LTRMP), authorized under the Water
Resources Development Act of 1986 (Public Law
99-662). The mission of the LTRMP is to provide
decision makers with information to maintain the
Upper Mississippi River System (UMRS) as a viable
large river ecosystem given its multiple-use
character. The long-term goals of the Program are
to understand the system, determine resource
trends and impacts, develop management
alternatives, manage information, and develop
useful products. The collection and distribution
of high-resolution aerial photography aids the
Center in meeting these goals.
- Supplemental_Information:
-
To make the data easier to download, the photo
mosaic has been compressed and is being served as
a georeferenced MrSid image. A software program
that contains MrSid image support or a MrSid image
viewer is required to view these data. A free
image viewer capable of subsetting, resampling,
and exporting the compressed image to
georeferenced TIFF image (a .tif image and a .tfw
world file) is available at
http://www.lizardtech.com/. The data are stored
in a Universal Transverse Mercator (UTM)
projection, zone 15. Two datum options are
available, North American Datum 1927 (NAD27) and
North American Datum 1983 (NAD83). NOTE: If you
use the software program ArcView GIS version 3.x
to view these data, you'll need to upgrade the
program MrSid dynamic link library file (.dll) if
you want access and use the NAD83 files. The
MrSid .dll file distributed with the 3.x versions
of the program does not read the image's world
files (.sdw), causing the images to always be
displayed in NAD27. New .dll files can be
obtained at
http://www.lizardtech.com/products/updates.html.

A digital orthophoto is a digital image of an
aerial photograph in which displacements caused by
the camera and the terrain have been removed. It
combines the image characteristics of a photograph
with the geometric qualities of a map. The
standard digital orhthophoto produced by the USGS
is a black-and-white, or color infrared, 1-meter
ground resolution quarter quadrangle image. The
accuracy and quality of USGS digital orthophotos
must meet National Map Accuracy Standards at
1:12,000 scale for 3.75-minute quadrangles and at
1:24,000-scale for 7.5-minute quadrangles.

The vector data in the 1989 land cover/use data
were used to check the spatial accuracy of the
georeferenced photos.
- Process_Step:
-
- Process_Description:
-
GIS interns placed each photograph in a scanner
with the photo's most northerly side directed
upwards. The photos were scanned using a 200 dots
per inch (dpi) image resolution, and the files
were saved as TIFF images. The photo image was
assigned a name that described the photo's (1)
flight line, (2) photo number, (3) the year in
which the photo was collected, and (4) a
distinction between true color and color infrared.
