Geographic Information Systems

Geographical Information Systems (G.I.S.) is charged with the responsibility of maintaining the parcel ownership, the road centerline, official address, and other spatial databases. A spatial database is a database which associates information with a location. For example, the property ownership "layer" not only describes the owner, id, and assessed value of a property, it precisely describes the location and shape of the parcel.  In addition, the G.I.S. department maintains several County internet mapping applications. The Grand Traverse County G.I.S. Department acts as a G.I.S. service center providing cutom maps, and conducting analysis upon request for county, local governmental units, and private sector agencies requiring geographically based information. It is envisioned that all capital improvements planning will be conducted on a fully integrated G.I.S. system, which when fully implemented will allow analysis of the effects of the improvements on the population, recreational facilities, roads, etc.

"The Grand Traverse County GIS Department is dedicated to providing high integrity spatial data and spatial data products."  

"To aid county decision makers by providing reliable, easily accessed, and affordable GIS products to both public and private consumers."
