One thought on “More California GIS real property mapping

  1. In Nassau county, NY, we have a similar and sometimes very valuable data base.
    A few years back, the county hired a private firm to re-assess all properties in the county. At the close of that daunting task, each and every property in the county was listed in a searchable data base along with all information such as lot and block etc, and the assessed value. It even displays a photo of the property at the time it was assessed.
