OIR GIS receives FGDC CAP grant.
As part of the National States Geographic Information Council (NSGIC) "50 States Initiative", OIR GIS Services has been awarded a grant by the Federal Geographic Data Committee (FGDC).

The intent of this project is to develop a business plan in support of developing an enhanced elevation dataset for the State of Tennessee. The project will involve soliciting input through contractor led regional TNGIC meetings throughout the state. The final product will be a written business plan that identifies the requirements, costs, and products necessary for building a statewide high resolution elevation dataset. OIR GIS Services will use the information provided in the business plan to educate the Information Systems Council (ISC) on the significance and benefits of this data with the intent on obtaining funding to support the data acquisition efforts.
