Abstract:

A computerized data base was developed, using Geographic Information System

technology, for the coal and water resources of the Powder River coal region of

southeastern Montana--an area with coal reserves of about 39.7 billion tons and

1989 coal production of 37.5 million tons. This report describes the data base

and documents and its layers. The data base was developed to assist agencies

having responsibilities relating to coal evaluation, leasing, and management to

more efficiently access, display, and analyze spatial data.

The data base currently contains the following 23 data themes or layers:

abandoned mines, aquifers, alluvial valley floors, boundaries, climate, coal

reserves and chemistry, coal stratigraphy, drainage basins, flood plains,

geographic names, geology, hydrology, land survey, land and land use cover,

permit sites, railroads, roads, saturated paste, streamflow, templates,

utilities, water quality, and wells. Each layer contains documentation

consisting of an index map showing the geographic extent of coverages in the

layer, coverage documentation, source-map information (where data were digitized

from maps), and attribute information for the listed coverages.
