Geographic Information Systems


GISWelcome to the Tipton County GIS webpage. You're probably wondering what GIS is. GIS (Geographic Information Systems) is a computer-based mapping tool that allows for the storage, editing and creation of spatial/geographic information. GIS can also perform geographic analysis based on what questions you need answered. What layers of information you combine depends on your purpose—finding the best location for a new commercial site, analyzing environmental situations, viewing similar crimes in a region to detect a pattern, and so forth. The Tipton County GIS Department is responsible for coordinating GIS data sharing among participating agencies on the GIS Board and with creating base map layers for use by these agencies and the public. Click here for a PDF presentation of TCGIS.

Tipton County GIS began in 2000, when the county learned it would be one of the first in the state to participate in the Tennessee Base Mapping Program. As a result of the project, Tipton County has high-quality GIS data and is well ahead of most counties in Tennessee. Data obtained from this project includes digital orthophotos (aerial photos) from 2000, parcels, street centerlines, and city boundaries.

The Tipton County GIS Board was created shortly after the county’s participation in the Base Mapping Project. The board is made up of 13 representatives from the following agencies and offices:

County Executive
Property Assessor’s Office
Planning & Development
County E-911 Office
Public Works Department
County Sheriff's Office
City of Covington
City of Munford
Town of Brighton
Town of Atoka

Covington Electric System
First Utility District
Poplar Grove Utility District

Our goal is simple: "To Serve the Mapping and Geographic Needs of Tipton County, TN". We accomplish this through:

1) Data Maintenance

2) Data Creation

3) Data Distribution

4) Participant Development and Assistance

5) Community Education

These agencies share information and are always creating new data for the GIS system. Click here to view the by-laws for the Tipton County GIS Board.

The TCGIS Board also uses a base cartographic standard for all maps published within the group. Click here to view the document.

North American Vertical Datum (NAVD) 88 - Vertical control datum established in 1991 by the minimum-constraint adjustment of the Canadian-Mexican-U.S. leveling observations. It held fixed the height of the primary tidal bench mark, referenced to the new International Great Lakes Datum of 1985 local mean sea level height value, at Father Point/Rimouski, Quebec, Canada. Additional tidal bench mark elevations were not used due to the demonstrated variations in sea surface topography, i.e., the fact that mean sea level is not the same equipotential surface at all tidal bench marks.
