Aerial imagery for the Upper Mississippi River System (UMRS) Navigational Pool 5 drawdown follow-up was collected in true color (TC) in August of 2015 at 6”/pixel using a mapping-grade Applanix DSS 439 digital aerial camera. All TC aerial images were orthorectified, mosaicked, and compressed into a JPEG2000-format image. The TC aerial images were interpreted and automated using a genus-level 150-class Long Term Resource Monitoring (LTRM) vegetation classification. The 2015 vegetation database was prepared by or under the supervision of competent and trained professional staff using documented standard operated procedures.

The 1989 systemic LCU data set provided an excellent learning experience, both in terms of how long such an ambitious undertaking would take, and the difficulties involved in applying a plant-based classification system to a dynamic and complex ecosystem. The 1:15,840-scale allowed for delineating vegetation units as small as a tenth of an acre but it soon became apparent that a minimum mapping unit was necessary to complete this data set by the end of the decade. While resource managers and scientists liked the unprecedented detail of the 1989 LCU, most analyses were performed on a generalized class that the species classes collapsed into. There was also concern over the length of time it took to complete the 1989...
To develop a data set that would allow for focused analyses at site-specific areas, true color (TC) and color infrared (CIR) aerial photography were collected in the late-summer of 1989 at a scale of 1:15,840. This was a ground-breaking effort to classify almost three million acres of the Upper Mississippi and Illinois River floodplains to the genus-level. The classification system was based on identifiable species, ccurring alone or mixed. To provide additional information, modifiers were added to these map classes that described vegetation density, or relative cover, and, in the cases of trees, a height modifier. Initially, it was unknown whether TC or CIR film would best for vegetation mapping and this is the...
The U.S. Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) program, through its Long Term Resource Monitoring (LTRM) element, collected aerial imagery of the systemic Upper Mississippi River System (UMRS) during the summer of 2020. A Land Cover/Land Use (LCU) spatial database was developed based on the 2020 aerial imagery, which adds a fourth systemic-wide database to the existing 1989, 2000, and 2010/11 LCU databases. The main purpose of the Land Cover/Land Use (LCU) spatial datasets is for resource managers and researchers to assess and evaluate current (2020) vegetation components and long-term vegetation trends of navigable pools (the stretch of river between locks and dams) and reaches of...
This set of non-spatial tables provides a detailed link (crosswalk) between the general classification within Long Term Resource Monitoring (LTRM) land cover/use (LCU) geospatial layers and the U.S. National Vegetation Classification (USNVC), current as of April 2017. The Upper Mississippi River Restoration (UMRR) Program’s LTRM element has produced LCU data over the past three decades consisting of geospatial layers (maps) showing locations of vegetation and developed lands within the Upper Mississippi River System (UMRS). The LCU data layers contain a classification of 31 general classes specifically developed to meet needs and objectives of the LTRM element of the UMRR Program. Because the LTRM classification...

Technology doesn’t stand still and neither does the vegetation mapping program. With 9X9 film and film cameras becoming increasingly rare, the 2010 systemic aerial photo effort will use a digital mapping camera to collect 8”/pixel imagery above Lock & Dam (L&D) 13 and 16”/pixel imagery below L&D 13 and along the Illinois River floodplain. There are two main reasons for this distinction; 1) the floodplain above L&D 13 is narrower and contains a greater amount and diversity of aquatic vegetation, and 2) below L&D 13, the Upper Mississippi River is largely channelized, with less aquatic vegetation, and wider, leveed floodplains dominated by agricultural use. This holds true for much of the Illinois River as well...

In the late 1880's and early 1900's the Mississippi River Commission (MRC) conducted an extensive high-resolution survey of the Mississippi River from Cairo, Illinois to Minneapolis, Minnesota. These data were published as a series of 89 survey maps and index. Other data on the maps that were not automated include; elevation contours, water depth soundings, proposed water control structures (e.g., wing dams), levees, benchmarks, railroads, and city streets. However, this information is available since these maps were scanned, georeferenced, and mosaicked by pool and are served on the Center’s web site. In addition to the mosaics, in the 1990's, the Upper Midwest Environmental Sciences Center (UMESC) in conjunction...

The Great River Environmental Action Team (GREAT) was a federal/state multi-agency cooperative program established in the late 1970's to evaluate current resource management practices and develop management strategies for the Upper Mississippi River (UMR). One of the problems facing the GREAT project was the lack of available information on many of the river's components. One project implemented by GREAT was the creation of a land cover/land use (LCU) database derived from color infrared aerial photography collected in 1975.
The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) is in the process of creating high-resolution land cover/use data sets for the Upper Mississippi River System (UMRS) from 1:24,000-scale color infrared aerial photos collected in 2000. The photos are being interpreted using a 1-hectare 10% minimum vegetation cover to delineate land cover/land use, percent vegetation cover, tree height, and hydrology regime. The geographic extent of the UMRS is the Mississippi River from Cairo, IL to Minneapolis, MN and the Illinois River from its confluence with the Mississippi near Grafton, IL to Lake Michigan.

Aerial photographs for Pools 2-13 Upper Mississippi River System were collected in color infrared (CIR) in August of 2010 at 8”/pixel and 16”/pixel respectively using a mapping-grade Applanix DSS 439 digital aerial camera. All CIR aerial photos were orthorectified, mosaicked, compressed, and served via the UMESC Internet site. The CIR aerial photos were interpreted and automated using a 31-class LTRM vegetation classification. The 2010 LCU databases were prepared by or under the supervision of competent and trained professional staff using documented standard operated procedures and are subject to rigorous quality control (QC) assurances (NBS, 1995). The 2010/2011 land cover/land use spatial data sets for pools...
