Interactive Maps

The SLV GIS/GPS Authority manages the data for the six counties of the San Luis Valley. Currently, we host an interactive online parcel viewer for Alamosa, Conejos, and Saguache Counties. Costilla, Mineral, and Rio Grande Counties host their data through other vendors. For your convenience, this Basic Valley-Wide Parcel Viewer contains the parcels and basic attributes, as well as the PLSS and public lands. It should be noted that for the most current data sets, please refer to the individual county parcel viewers/websites.
