Summary Of State Grants For Mine Mapping - Alabama
The State of Alabama received a grant of $51,000. In 2005, the Geological Survey of Alabama initiated a project to create an ArcGIS-based system that would geographically organize and display the collection of approximately 2,000 underground coal mine maps maintained by the Alabama Department of Industrial Relations. The goal was to complete a project for a small geographical subset of the maps. Tuscaloosa County was chosen since it has a relatively small number of historical mine maps, but also has several active mines. The maps were taken to the Geography Department of the University of Alabama for scanning since the survey had no wide-format scanner. Twenty-eight historical maps were scanned and the images geo-referenced during the project. Additionally, three digital maps were made available for the active coal mines. The ArcGIS project, when completed, included the following layers: 1) political boundaries, 2) 7 ½' topographic maps, 3) geo-referenced mine footprints (color coded by coal group) that when clicked on would bring up both metadata and a map image, and 4) coal data points from the National Coal Resource Data System. Since the completion of this trial project, they have acquired their own 42-inch large format scanner, and efforts have concentrated on the scanning phase in order to complete the image archive of the map collection as soon as possible. |
