GIS / Mapping

GIS (Geographic Information Systems) is often described as "computerized mapping" but it is much more. GIS combines layers of information to provide a better understanding of a geographic area (spatial location). GIS is an exciting, dynamic and rapidly advancing technology of computer software, hardware, data, and personnel used to manipulate, analyze and present information that is tied to a spatial location.  GIS has become an essential part of La Plata County's daily functions.  GIS is used in several of the County's departments including: the County Assessors Office, Planning Department, Office of Emergency Management, Road and Bridge, and Engineering.
