The Blount County GIS Group (BCGIS) provides GIS support to the Cities of Alcoa and Maryville, and Blount county government.


A geographic information systems (GIS) is a collection of computer hardware, software, and geographic data that is used in concert to capture, manage, analyze, and display all forms of geographically referenced information.  With that said, another way to visualize GIS is to think of it as a smart map.  One in which we are able to associate database information to points (fire hydrants or manholes), lines (street centerlines or water mains), and polygons (parcel boundaries or soil types).  This information, stored in a centralized data repository, can then be used to create maps or perform analysis so that informed decisions can be made.


Early development of GIS within Blount County began in the 1994 with a base mapping project for the City of Maryville.  The early 21st century saw GIS development continue in the county with two mapping projects:

  1. Integrated Pollutant Source Inventory (IPSI) project.  This was a collaborative project between the County, TVA, and the US Department of Agriculture (USDA) to identify nonpoint pollution sources in the county watersheds.
  2. Tennessee State Base Mapping Program.  This was a collaborative project between the State, the County, Alcoa, and Maryville that generated highly accurate digital orthophotography, tax assessor parcel data, and street centerlines.


These two projects set a precedent of cooperation that continues to this day. 


The BCGIS was formed in mid-2005 by an intergovernmental agreement between the cities of Alcoa and Maryville, and Blount County government.  The purpose of this group is to provide oversight and guidance with regard to developing GIS policies; manage and develop joint fiber optic assets; develop, populate, and maintain a countywide GIS database; and provide analysis and support to all departments within the three governments on integrating GIS within their present workflows.  One goal of the BCGIS is to carry out its mission in the most practical, cost-effective, and efficient manner possible. 


The development of GIS within Blount County is still very much a work in progress.  One of the goals of this endeavor is to make certain information available to the public through a web portal.  Please check back often to view our progress.
