- Abstract:
-
The U.S. Geological Survey's Upper Midwest
Environmental Sciences Center (UMESC) collects
aerial photography of the Upper Mississippi River
System (UMRS) floodplain on a regular basis.
These data are used to support the Center's
long-term goals of understanding the UMRS and
developing useful products for the Long Term
Resource Monitoring Program (LTRMP). In 2000,
1:16,000-scale true color aerial photos were
collected on the Mississippi River from Cairo, IL
to Minneapolis, MN and the on Illinois River from
its confluence with the Mississippi near Grafton,
IL to Lake Michigan/Chicago, IL. The photos were
collected using a 60% stereo overlap between
photos in the same flight line and a 30% overlap
between flight lines. At the time this document
was prepared, UMESC was in the process of
scanning, georeferencing and compiled
approximately every other photo into georeferenced
mosaics for the navigation pools. These mosaics
are served as compressed .jp2 images, so they'll
be easier to download vial the Internet. Note:
While the photos have been georeferenced, they
have not been orthorectified.
- 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:
-
In 1989, UMESC and the LTRMP began collecting
aerial photos of the Upper Mississippi River
System from Cairo, IL to Minneapolis, MN and the
Illinois River from its confluence with the
Mississippi near Grafton, IL upstream to Joliet,
IL. In years past the extent was road/railroad to
road/railroad. In 2000, the area photographed was
expanded to bottom of the bluff to the bottom of
the bluff. The
data are stored in Universal Transverse Mercator
(UTM) projections, zone 15 North American Datum
1927 (NAD27).

-
The horizontal positional accuracy is tested by
visual comparison of the data on-screen with
existing data sets that cover the same area. The
basemaps used to register the photos are 1:12,000
digital orthophoto quadrangles (DOQQs) (where
available) and 1:24,000-scale (24K) U.S.
Geological Survey (USGS) Digital Raster Graphics
(DRGs, scanned and registered images of USGS
quadrangles). DOQ files are positionally more
accurate than 24K DRGs. It is also easier to
match features on a DOQ than it is to the abstract
representations used to symbolize DRGs.

- Other_Citation_Details:
-
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.

A digital raster graphic (DRG) is a scanned image
of a U.S. Geological Survey (USGS) standard series
topographic map, including all map collar
information. The image inside the map neatline is
georeferenced to the surface of the earth and fit
to the Universal Transverse Mercator projection.
The horizontal positional accuracy and datum of
the DRG matches the accuracy and datum of the
source map. The map is scanned at a minimum
resolution of 250 dots per inch.

Data set used to check the registration of the
photo mosaics.
- Process_Step:
-
- Process_Description:
-
The 2000 aerial photos were processed one
navigation pool's worth at a time. To provide
photo interpreters with stereo coverage, the
photos were collected using a 60% overlap between
photos within the same flight line and 30% overlap
between adjacent flight lines. To reduce the
number of photos that needed to be scanned, all
photos were laid out geographically on a table so
the photo overlaps could be reviewed.
Approximately every other photo was pulled from
the collection and set aside.

- 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.

- Process_Description:
-
Each photo was georeferenced using Image Analyst
1.0 Extension for ArcView 3.2. The base imagery
in all cases was either 1:12,000 DOQ images or
1:24,000 DRG data. Root mean square (RMS) errors
under 7.0 were desired for all areas.

After an entire pool's worth of photos were

A quality check was performed on the full pool
mosaic. USGS DRGs, USGS DOQQs, and UMESC 1989 LCU
data were used to accomplish this Quality
Assurance/Quality Check (QA/QC).
