Coal Information Map

This map layout is designed to provide easy access to coal related information. The map display features the traces of mapped coal beds in the eastern and western coal field. Beds are labeled with the seam abbreviation that was used on the original GQ map. Non-coal beds (mainly clay and limestone) are also shown, because they are often related to coal bed horizons.

Coal thickness measurements, collected from surface outcrops and mines, are shown as orange + symbols. The points are labeled with the measured total coal thickness. Results of the identify tools list the bed name, the source of data, total coal and parting thickness, and elevation at the base of the seam. The zoom button will refocus the map to an individual point measurement at a scale of about 1:5,000.

Coal boreholes that have been donated to KGS are shown as orange-centered circles. The holes are labeled with a unique identifier. The results of the identify tools provide summary information about the hole with links to reports of subsurface descriptions and coal bed summaries. Clicking the Hole ID link opens a window with a graphic strip log of the hole. An SVG plug-in is required to view these images. If the image does not appear in the window, click the link to the plug-in download site and install it.

To view mine information for the same area, click the KYMAPS icon at the bottom of the screen, then select one of the three sites listed under the mining section. That service will open in a new browser window, zoomed to the extent of your original map.

Overview of Map Functionality
Most of the map functionality is provided in the tabs on the right-side of the map interface:

Tools. The tool tab contains standard tools for zoom and pan control of the map. In addition there are several custom tools:

Query. This functionality allows you to search the Kentucky Geological Survey database for geologic descriptions from KGS publications, maps, and field notes and highlight those units on the map. Follow the instructions on the tab for more information about using this feature.

Legend. This tab provides explanations of symbology for the map layout. The map unit colors display the map colors for the units in the viewed extent. Other map symbols are displayed below the colors and are also displayed with each map layer on the "Layers" tab.

Layers. This tab provides controls for changing the layout of the map. There are three main sections in this tab: Geologic Information. There are two ways to get information about geologic units or other features on the map. The identity tool , described above, is used to gather information about specific features. It works by clicking on the map and the results are sent to a pop-up window. The identity tool only returns descriptions from the 1:24,000-scale GQ's. Be aware that the sensitivity of the tool is scale-dependant. Clicking at small scales may return descriptions for multiple map units or features.

The Geologic Information tab provides comprehensive searches for all information that pertains to the map extent. Because of the larger amount of information that is accessed, the searches are provided from individual links. The results are grouped by type of source and then by the individual source title. The source title is a link to the KGS online list of publications, where many publications can be viewed. For lithology descriptions, a portion of the graphic stratigraphic column is provided for context, and the full stratigraphic column is accessed from a link.
