Carter Coordinate Conversion Software

The land grid in Kentucky is the Carter coordinate system. A utility is available to perform conversions between Carter and geodetic (lat/lon) coordinate systems. The utility has been tested on Windows 3.x, 95, 98, NT, and 2000. Originally written in Borland Turbo Pascal, the source code is being updated so it can be compiled with the Free Pascal compiler.

Notice: The Carter coordinate system was defined using U.S. Geological Survey 15-minute, 1:62,500-scale topographic maps and is currently based on 7.5-minute, 1:24,000-scale topographic maps. The datum for Carter coordinates is the North American Datum of 1927 (NAD27). The decimal latitude and longitude coordinates output by the program will be NAD27.

A Carter Coordinate and Topographic Map Index (568k) is available as an Adobe Acrobat pdf for viewing or printing.

Click to download a copy of the distribution file. When prompted, save the file to your local hard drive. The file is a self-extracting compressed archive file. Execute the file to extract the components. The KyGeoTools ActiveX component is the preferred method for converting Carter coordinates to latitude and longitude.

For more information on installing and using the program, click to view a pdf version of the documentation file. The Adobe Acrobat reader is required to view the documentation. Visit Adobe and click on the Get Acorobat Reader button if you need the plug-in.
