CEHTP Centralized Geocoding Demonstration
  • This web page is an example of a client that utilizes the California Environmental Health Tracking Program's (CEHTP) centralized geocoding service.


  • Problem
    • Historically, health event data have imperfect geocoding success rates.
      e.g. Birth Master File = 95%, Medi-Cal = 85%.
      We want 100%!
    • High quality address data, or, more preferably, pre-geocoded data, prepares CEHTP to perform ongoing/systematic/automated GIS visualization and spatial linkage with environmental hazard datasets. Geocoding should be done as early as possible in the data collection process.
    • Programs that receive reported data and compile them for official release might not have resources or mandate for geocoding or ensuring high quality address data. Geocoding can be expensive.
    • Programs may desire GIS visualization services for their data product. This is not possible unless the geography of the data is coded and of high quality.
