Uses of CPAD Data

CPAD GIS data on fee-owned open space lands is appropriate for many uses, including:

  • Development of city and county general plans
  • Strategic planning for conservation
  • Assessment of options for trail systems
  • Display maps of recreation opportunities
  • Assessing sites for renewable energy location
  • Monitoring of lands
  • Analysis of areas where urban parks are needed

CPAD data are not necessarily the same as the GIS data maintained by owning or operating agencies - the data from owning agencies should always prevail in any conflict about boundaries or attributes. Because CPAD is a statewide data set, it is generally aligned to county assessor parcels for consistency - assessor parcels are not always accurate, particularly in rural areas, and owning agencies may use alternative means of setting their property lines.  CPAD may also not use all of an agency's data (e.g., CPAD generally excludes hardscape sites such as swim centers or other mostly-built sites).

In addition, CPAD data should not be used for determining any property boundary, legally enforceable regulation or other binding governmental action - source agency data for the area concerned should be used instead.  CPAD is a general purpose data set for planning and other such purposes - see the CPAD data disclaimer in the User Manual for further information.
