These data cover all Wilderness Areas designated by Congress in Montana. They are extracted from the statewide land ownership and managed areas layer maintained by the MTNHP.

Montana Population in persons per square mile from the 2000 Census. This data is a smoothed-over representation of Montana's population density surface, designed to emphasize small areas with high population density. It was derived from U.S. Census Bureau 2000 TIGER files and population counts. The original data was resampled to a 100-meter grid, smoothed, and the highest resulting density of the 100-meter cells in each 1-kilometer grid cell was assigned to the cell. When comparing this data set to the similar data set available from NRIS for the 1990 Census, it is important to realize that the change of population density at a location is likely to be the result of a change in the configuration of the Census...

This database provides information on Public Water Systems (PWS) and facilitates access to Source Water Protection Program reports that are referred to as Source Water Delineation and Assessment Reports (SWDARs). A public water system is a system that serves 25 or more people or has 15 or more service connections and operates at least 60 days per year. The Department of Environmental Quality (DEQ) regulates all types of PWSs in Montana with the exception of those owned and operated by the Native American nations. There are currently over 2,000 PWSs in Montana and between 75 and 100 are added each year. There are three general classes of PWSs. Community (C) PWSs serves a community of year-round residents; towns...

Mining Districts of Montana, developed by the Montana Abandoned Mines Reclamation Bureau. Based on a map of minining districts made in 1935, with some districts revised or removed, with addtional districts added. The districts were revised again in May of 1995. Mining districts were formed by associations of miners in a region who developed rules and laws to govern mining in the district. They sometimes established a monument to serve as the reference point for surveys in the district and created a description of the district boundary. Mining districts are no longer legal entities. Historical narratives describing the mining districts and their boundaries are available at http://deq.mt.gov/abandonedmines/linkdocs/default.mcpx.

These data cover the National Park Service (NPS) units in Montana. They are extracted from the statewide land ownership and managed areas layer maintained by the MTNHP. The names of the NPS units have been provided in the NAME attribute field. Privately owned areas inside NPS units have a NAME of "inholding".
These are all of the roads from the U.S. Census Bureau 2000 TIGER files. Most of the roads were digitized from 1:100,000 scale maps by the US Geological Survey. Roads added to the database after 1990 were digitized by the Census Bureau from various sources. Some roads that exactly follow county lines exist twice in the TIGER database -- once for each county that they appear in. One of each of these pairs has been removed from the version of this data set that is on the SDE server at the State Library and the statewide shapefile on the web site. The individual county shapefiles on the web site are also missing these duplicate roads, so most county shapefiles will not have all of the roads that fall exactly on...

American Indians (1990) per square mile. Derived from U.S. Census Bureau TIGER files and population counts. The original data was smoothed, and the highest resulting density in each 1-kilometer grid cell was assigned to the cell. See /gis2/montowrk/cmp/94/94nris98e.aml for the exact method used to create this grid.

Montana's landscape is a complex, constantly changing patchwork of federal, state, private and tribal ownership. Within these ownerships are many kinds of designations, including wilderness, parks, wildlife areas, recreation areas, and conservation easements. Because information on land stewardship is critical to effective land management, the Montana Natural Heritage Program began integrating ownership and management data into a land stewardship mapping data system in 1997. The goal of the Montana Land Stewardship Mapping Project is to manage a single, statewide digital data set that incorporates information from both public and private entities. The project assembles information on land ownership and management,...

These data cover designated National Wildlife Refuges (NWRs) in Montana. They are extracted from the statewide land ownership and managed areas layer maintained by the MTNHP. Only the outer Refuge boundary is included here. Many refuges contain "inholdings" that are not owned by the US Fish & Wildlife Service (USFWS); but these inholdings have been deleted from this data set to simplify the representation of these areas. The name of each Refuge is provided in the NAME attribute field.

Water Resource boundaries were created by reselecting arcs from the 1:100,000 TIGER county coverage. Information came from an ascii file provided by DNRC, "Water Resources Division Regional Offices." For more information, see /gis2/montwork/cmp/94/94nris172d.aml

Mine locations from the U.S. Bureau of Mines Mineral Information Location System (MILS) database. Provided to NRIS by Frances Baker of the Spokane office (509-353-2738 or 509-353-2712). This data was provided to BOM from many State and Federal agencies, and the coordinates come from sources of varying accuracy. The attributes included here are a subset of those available from USBOM. Data from BOM's "one-liner" report on 9/1/1992.

Montana/Dakotas BLM changed from a 'three-tier' organization (state office/district office/resource area office) to a 'two-tier' organization (state office/field office) several years ago. These data reflect the new 'two-tier' organization. These data depict Bureau of Land Management (BLM) administrative units (Field Office boundaries) in Montana. The attribute data include the name and contact information for each Field Office.

This data set shows the national forest and ranger district boundaries in Montana, and national forest land that is outside the forest boundaries. It does not distinguish among federal, state, and private lands that are inside the forest boundaries. For actual land ownership, see http://nris.mt.gov/nsdi/nris/ab105.html. In the Arc/Info coverage version of this data, National forests are represented by a 'region.forest' feature class and ranger districts by a 'region.district' feature class. In the shapefile version, each polygon has a field for the forest and district name and attributes of the districts in its attribute table, and there is an additional table called forests.dbf that contains information about...
Estimated wind power distribution of Montana. This is a raster data set in which each 400-meter pixel represents the average power of the wind in watts per square meter at an elevation of 50 meters above the ground. These wind power resource estimates were produced by TrueWind Solutions using their Mesomap system and historical weather data. This map has been validated with available suface data by the National Renewable Energy Laboratory and wind energy meteorological consultants. The estimates tend to be more accurate for the plains than for mountainous areas. For more information, see http://www.windpowermaps.org and read the Use_Constraints section below.

One-kilometer Digital Elevation Model for Montana. This data is from the EROS Data Center 30-second Digital Elevation Model of North America, which was derived from the Digital Chart of the World 1:1,000,000 scale contour and hydrography data.
