OMSIUA GIS APPLICATION Th e OMSIUA GIS application consists of a toolbar featuring a mixture of native ArcGIS tools and several custom-designed tools using VBA for ArcObjects (fi g. 5). To locate mine subsidence claims, two tools are used to zoom into the claim location and load all geologic maps and documents. Th e toolbar contains the native ArcGIS Find Tool (fi g. 6), which is used to locate insurance claims using the Address Locator function. Th e second tool, the Selection Location Tool (fi g. 7), will load all known digital geologic maps and GIS data for a mine subsidence location into the ArcMap document for that location. Some of the GIS datasets include abandoned underground mines; permitted surface mines; 1:24,000-scale bedrock geology; and the one-foot resolution, digital orthophotography. One of the most important sets of historical records is the collection of 15-minute thematic geologic maps. Th ese maps have been scanned and indexed. Th e Select Location Tool will identify all scanned maps within a one-mile radius and load them into ArcMap (fi g. 8). Once the information is loaded, the geologist can conduct a preliminary mine subsidence analysis. Th e Underground Mine Information Form (fi g. 9A) will present the attribute information on abandoned underground mines. Using the form, georeferenced abandoned mine maps can be loaded into ArcMap (fi g. 9B). Documents can be accessed using the native ArcGIS Hyperlink Tool (fi g. 10). Some of the documents that can be accessed are measured stratigraphic sections, core descriptions, and oil-and-gas well completion cards—all of which can have a description of a coal bed within them and possibly the notation that an underground mine is nearby. After the analysis is completed, portions of the preliminary mine subsidence report can be automated. A tool will export thematic, page-sized, PDF maps (fi g. 11A). Th e page-sized maps are generated with the correct titles (fi g. 11B). Th e PDF maps, along with all the geologic documents within one mile of the site will be exported to
