River Environments Active

Land/water is one of the classification attributes in the land cover/use data sets created by UMESC from aerial photography. These data are redistributed here as shape files with the boundaries of the region's 1:24,000-scale USGS quadrangles added to the data. 

Light Detection And Ranging (Lidar) generates extremely accurate (vertical and horizontal) location information and has long been a desired product for the Upper Mississippi River System (UMRS).

Bathymetric data are collected with an automatic survey system and processed in a Geographical Information System (GIS). Through interpolation the individual points of water depth are converted into a water depth map.

A statistical model to predict the probability of occurrence of submersed aquatic vegetation in Pool 8 of the Upper Mississippi River on the basis of a few hydrological, physical, and geomorphic variables. (Project summary)

This tool allows the user to view and identify several land cover data sets within the Upper Mississippi River System. 

This tool allows the user to view several scanned and georeferenced historic map image mosaics. Data is available for viewing by selecting the layer list button described below, and checking the boxes next to the data layers of interest. There are other tools that allow map creation, distance and area measurements, and drawing tools.                              

The Upper Mississippi River Restoration (UMRR) Program Long Term Resource Monitoring (LTRM) element has collected millions of records of information over 20+ years. Fisheries, water quality, vegetation, and invertebrates have all been sampled. Geographic locations were collected for all sampling points. 

This web mapping application provides access to many of Grand Canyon Monitoring and Research Center’s most commonly used map layers in support of science efforts occurring throughout the Colorado River corridor.
