      Welcome to CCMap!  The Contra Costa County GIS web site is dedicated to bringing maps and spatial information to the public, county staff and our partner agencies. Here you can find information about where we live, work and play.
        Geographic Information Systems (GIS) are used to link maps together with information to provide a rich environment to discover our world. View aerial imagery for any area in the County, check your zoning, find assessed property values around your home, check your lot size and much more!
