Welcome to Logan County's' Geographic Information System. GIS in Logan County has been under development for several years. Results from this effort are continuing to become available. Check out the Examples tab for ways that GIS is currently being used in Logan County.

Much of the data that has been developed is available for public viewing through the Internet Mapping application. Internet mapping allows for the user to view the existing GIS layers on their personal computer. The GIS data layers available for viewing on the Internet Mapping site are found in the Map Contents box that appears on the left side of the Internet Mapping page. To view a layer, check the box for the specific layer you want to view. In some cases it will be necessary to also check the box for the general layer name. For example, if you wish to view Library District boundaries, both Library Districts and Other Taxing Districts layers must be turned on by clicking in the empty box. Where there is a box with a plus sign (+) in it, there are additional data layers associated with that layer. To expand a layer, click on the (+) sign.

Single layer GIS maps have also been created and can be found in the Map Gallery. These countywide maps are in a .pdf format and do not require navigating the full Internet Mapping application.

Data is also available for purchase. Paper maps and digital data are available from the GIS Committee. Check out the Data tab for information on current fees and licensing agreements.

Vision Statement

The Logan County GIS Committee is committed to create a regional GIS infrastructure that includes base data, hardware, and software to meet the geographic information needs of the County as well as other participating public and private stakeholders.
