Abstract:
The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) collects 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 1999, 1:15,000-scale color infrared aerial photos were collected for LTRMP study areas. The 1999 photos of the Weavers Bottoms area were scanned and georeferenced to provide a reference image for a restoration project.
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.

Data_Quality_Information:
Completeness_Report:
The LTRMP study areas were flown using a 60% stereo overlap between photos in the same flight line and a 30% overlap between flight lines. The mosaic was created using every other photo, except in cases where the following occurred; Extreme
Cloud_Cover:
, Extreme Local Relief, Sunspots on the ground, and Tilt or yaw distortions caused by the position of the plane.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
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 was a digital orthophoto quadrangle.

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.

Process_Step:
Process_Description:
The step in creating photo mosaics is to select which photos will be scanned and georeferenced. 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_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.
