Drainage Index and Productivity Index

    This website is designed to help you calculate the Drainage Index (DI) and Productivity Index (PI) of all soils that are classified within the US system of Soil Taxonomy. These data aid in the identification of areas at risk to various forest insects and diseases because of their ability to identify regions of potential tree stress.

    USDA Forest Service Remote Sensing Applications Center and Geospatial Technology and Applications Center

      The Forest Service's Remote Sensing Applications Center (RSAC) is in Salt Lake City, Utah, co-located with the agency's Geospatial Service and Technology Center. Guided by national steering committees and field sponsors, RSAC provides national assistance to agency field units in applying the most advanced geospatial technology toward improved monitoring and mapping of natural resources. RSAC's principal goal is to develop and implement less costly ways for the Forest Service to obtain needed forest resource information.

      Intermountain Region (Region 4) Geospatial Data

        The GIS datasets available from this site are provided in ESRI .shp. All data available for download uses the current National ADS Standard codes. Many of the data files have also been zipped for compression. Each zipped file will contain ADS boundary and damage layers, and ADS GIS Handbooks and appendices.

        Shawnee National Forest Geospatial Data

          GIS data is available on the Forest’s FTP site in the form of “shape files” or layers and is available free for downloading. To utilize these data layers you will need a program that uses the Geographic Information System (GIS) such as ESRI’s ArcMap, ArcView or the free map reading program ArcGIS Explorer. ArcGIS Explorer has tools that let you zoom in/out, print the map, and query data. It also has map tips to identify features, and a help menu. Included is a list of GIS data files available for the Shawnee National Forest. These GIS data files are updated on a continuing basis.

          Rocky Mountain Research Station Air, Water, & Aquatic Environments Program

            The Air, Water, and Aquatic Environments (AWAE) research program is one of eight Science Program areas within the Rocky Mountain Research Station (RMRS). Our science develops core knowledge, methods, and technologies that enable effective watershed management in forests and grasslands, sustain biodiversity, and maintain healthy watershed conditions.

            Monongahela National Forest Geospatial Data

              Selected geospatial data that encompass the Monongahela National Forest are available for download from this page. A link to the FGDC-compliant metadata is provided for each dataset.

              Farm Service Agency Aerial Photography Imagery Products and Programs

                APFO is home to one of the country's largest aerial film libraries. We currently house more than 70,000 rolls of film (10 million plus images). Our film dates from 1955 to the present. We have coverage of most of the United States and its territories. Historic aerial images play a more vital role today than ever before with environmental assessments, change detection, and property boundary disputes.

                Ecoregions of North America

                  Ecoregions are identified by analyzing the patterns and composition of biotic and abiotic phenomena that affect or reflect differences in ecosystem quality and integrity. These phenomena include geology, landforms, soils, vegetation, climate, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another regardless of the hierarchical level. A Roman numeral classification scheme has been adopted for different hierarchical levels of ecoregions, ranging from general regions to more detailed. Included in this dataset is additional details about each level, and downloadable maps and GIS data files.

                  NRCS Regional Conservation Partnership Program - California Bay Delta

                    Noteworthy for its agricultural productivity, ecological diversity, and complexity, the Bay Delta is one of the largest and most complex water delivery systems in the nation. The Sacramento River and San Joaquin River meet in the Delta, which provides water to one of the most significant estuary ecosystems in the United States and provides drinking water to 25 million Californians. The Bay Delta offers habitat to 55 species of fish and 750 species of plants and wildlife. This dataset includes a printer-friendly CCA map and shapefiles for GIS.

                    NRCS Regional Conservation Partnership Program - Prairie Grasslands Region

                      One of the most threatened ecosystems in North America, native prairie and grasslands contained within the Prairie Grasslands Region are essential habitat for a number of wild game and threatened species, including the lesser prairie chicken and sage grouse. The region also encompasses the Red River Basin of the North and the Ogallala Aquifer—areas that are facing critical conservation needs on working lands from frequent flooding and ponding (in the north) to prolonged drought and aquifer decline (in the Ogallala). This dataset includes a printer-friendly CCA map and shapefiles for GIS.
