TNMAP aids Economic Development for VW suppliers
The Department of Economic and Community (ECD) Development has partnered with OIR GIS Services in the development of a GIS application to support the new VW plant in Chattanooga. Potential part suppliers to the new VW plant can search an online GIS database to identify potential land or building locations. A total of 42 sites within a 60 mile radius of the new VW plant site in Chattanooga are included in the online GIS database. Potential VW suppliers can search each of these locations in proximity to the VW plant and query additional information including: size of property and buildings, proximity to interstate and rail service, available utilities, proximity to flood hazard area, land use factors, and pictures of each location. This GIS application leverages data developed from the Tennessee Base Mapping Program and other GIS business data developed by ECD, and represents another opportunity to promote GIS and the value of the Tennessee Base Mapping Program in support of economic development.
