|New Web Application Uses GIS to Map Civil War Sites in Tennessee...|
Most Tennesseans may not stop to reflect on the state's role in the Civil War as they go about their daily lives, but now interactive technology coupled with extensive historical research can map out the battles that took place where present day grocery stores, schools and businesses stand. The first of its kind in the nation, the Tennessee Civil War Geographic Information System (GIS) Survey shows hundreds of locations where Civil War battles, engagements, skirmishes and other military actions took place.

|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.

|ESRI has announced a new global grants program for non-profit groups.|
|Called the "ESRI nonprofit program", and located at http://www.esri.com/nonprofit/, it's a streamlined way to get a cheap 1-year license of Arc/INFO, ESRI's flagship GIS software. All of their existing grant programs like ECP and Techsoup continue in full force and for the most part, grants from any program don't exclude you from eligibility for other programs. Techsoup in particular continues to grow and add new tech content of interest to any nonprofit. Each program is different, so pick the one that best matches your needs. A new site at http://www.esri.com/grants summarizes all of their grant programs in relation to one another.|
|TNMAP to host Civil War Battlefields map site.|
|The Tennessee State Library and Archives (TSLA) and OIR GIS Services will use a grant from the National Park Services American Battlefield Protection Program to develop a GIS enabled database of the state's Civil War battlefields. The site will be available for federal, state and local planning agencies as well as the general public.|
The site will link information from the Civil War Sourcebook for Tennessee to Civil War maps and documents archived at TSLA. This enhanced resource will be available on TSLA's section of the Tennessee Department of State web site.
GIS technology has become one of the major tools used by planners who are trying to protect and preserve Civil War battlefields.
