Why was the data set created?

The Nation's coal resources are being assessed by the USGS. This assessment identifies and characterizes the coal beds and coal zones that will provide the bulk of the Nation's coal-derived energy during the next few decades. This assessment is different from previous USGS assessments because digital files and databases are being collected and stored in standardized formats,and being analyzed using a Geographic Information System (GIS).

How was the data set created?

2. How were the data generated, processed, and modified?

   Date: 1998 (process 1 of 1)

   Stratigraphic data were compiled in a Stratifact relational database. These data were correlated and the coal beds were identified. Stratigraphic data for the coal and rock units in the coal zone were downloaded from Stratifact and run through a custom "parting/split" program to calculate net coal thickness at each data location. This dataset was then linked to all available coal quality samples on the following parameters. The latitude and longitude, surface elevation, and coal top and bottom (thickness) for each coal location was compared to the latitude and longitude, surface elevation, and coal top and bottom (thickness) each stratigraphic location. When a match was found, the two files were given the same identification code. This identification code linked both the stratigraphic and coal quality databases. Coal quality data that could not be match with the corresponding stratigraphic data was only utilized for summary tables and bubble maps. This joined dataset was then imported into ArcView and converted to a shapefile.

Are there legal restrictions on access or use of the data?

Access_Constraints: None

Use_Constraints:

This dataset is meant for general display and query purposes only in the ArcView Project and should not be used for any other purpose. Terminated, confidential and interpretive points have been removed from this dataset. In addition, the net coal thickness values within this dataset have been modified from their original value for resource calculation purposes. A complete dataset can be obtained from the United States Geological Survey's, National Coal Resource Data System.
