More KGS Web Map Services
You only need your web browser on your computer or mobile device to use the map services below for viewing and querying Kentucky geologic maps and data.
Detailed (1:24,000-scale) geologic maps and their descriptions can be viewed for all areas of the state.
Additional themes that relate to geology, land use, environmental protection and economic development can be overlain on
the geologic base. Also, descriptions of rock units, their behaviors and economic uses can be accessed using the search tools.
The Geologic Map Information Service displays
KGS-hosted geologic map data. With this service, you can quickly zoom and pan to view the geologic map for an area of interest, overlay and identify other KGS data
(water, oil and gas wells, coal, etc), view a detailed legend, and query and access information about the geologic units.
The KGS GeoMobile service is a
mobile web application that can be used in a variety of supported mobile devices (iPhone, Android, Blackberry, etc..) and
tablets (iPad, Galaxy Tablet, Kindle Fire, etc...) for displaying Geologic formations, oil and gas fields and wells,
mapped sinkhole outlines, and other geologic information. Only a mobile web browser is needed to use this service (no "app"
to download).
Users will need data access and GPS capability will enable zooming to your location.
KGS GeoMobile uses the jQuery mobile framework, and a list of
supported devices can be found here (this application requires an A-grade platform for complete functionality).
Connect and Download Map Data
Connect to KGS Map Services using Desktop GIS
Detailed instructions on how to access KGS data for use in desktop GIS software without having to locally download GIS datasets. A directory of available services is also provided.
Geospatial Data Library
The Kentucky Geological Survey and other state and federal agencies have electronic maps and GIS data that you can download for your use. The KGS GIS data are in ArcView shapefiles (registered by ESRI). The files were zipped using the WinZip utility. All the KGS datasets, unless explicitly noted, are in latitude and longitude, decimal degrees, NAD 83.
Water Map Services:
KGS hosts several services that allow you to view and query water well and spring data, karst potential information, and
groundwater water quality data. The water well/spring and groundwater quality data are also searchable through the
groundwater information database search service.

Coal, Oil, and Natural Gas Map Services:
Use the map services below to view and query Kentucky energy infrastructure information,
oil and gas well data, coal information, and core and sample data.
Much of the data displayed on these map services can also be found (and downloaded) through the
oil and gas database, coal database, and
samples and core library database search services.

Coordinate Conversion Services
- Convert A Single Coordinate Value
Use this service to convert a single coordinate value (lat/lon, KY single zone, carter coordinate, etc..) to 14 different coordinate values. Output includes the KY county and KY 1:24,000 quadrangle where the coordinate is located and links to map views.
- Convert Multiple Coordinates
Use this service to convert a delimited text file of coordinate values (guidelines given on the page) to a choice of 14 different coordinate values. Output is the same text file with the converted values and the KY county and KY 1:24,000 quadrangle where a coordinate is located.
- Publications & Maps
Search for KGS publications, published maps, and map data. Many publications and maps are viewable online for free through this service.
- Oil & Gas Information
Use these services to search for and view KY oil and gas data including oil and gas well records and oil and gas production data.
- Groundwater Information
These services can be used to find various types of KY groundwater data including water well and spring records and groundwater quality data. Click here for information about changes to the Groundwater Data Repository database.
- Coal Information
Use these services to search for coal data in both the eastern and western Kentucky coal fields. Data includes borehole (including lithologic and seam data), thickness, production, and quality.
- Well Sample & Core Holdings
This service allows you to search the KGS well sample and core library database.
- Photos and Images
Use a wide-range of criteria to search for and view images in the KGS photo catalog. Many of these images were taken by KGS staff and include information about the location (including a map link) and a description of the image.
- Geologic Descriptions
Search the entire KGS database for geologic descriptions (lithologic, economic, hydrologic, etc...) descriptions from KGS publications, maps, and field notes.
- KYTC Geotechnical Data
The Kentucky Transportation Cabinet and the Kentucky Geological Survey have partnered to provide the results of geotechnical investigations to the public. Search geotechnical reports, geotechnical boreholes, and view geotechnical data on an interactive map.
Listed below are various tutorials and presentations on using the KGS Maps and Database services. Added as they become available. If you have an
idea/request for a tutorial, please contact us via the feedback form.
