Summary

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 1930 photo mosaic for Mississippi River Navigation Pool 21 was created using 1:12,000-scale black-and-white photos collected during 1929-1930 probably late summer).

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.
