Welcome to the lead-public wiki!

Main data sources:

• CDPH Blood Lead Levels
• WIC Data
• Clinics using the API
• American Community Survey
• Building footprint from the data portal
• Assessor tax records

Geocoding is used in bulk in three places: the CDPH BLL data and the WIC data. Previously CDPH would manually geocode this data before uploading it to servers for DSSG, but going forward we can do the bulk geocoding directly. With the clinic data we will also need to geocode the address and perform address cleaning as well.

Geocoding will need to be implemented on a real time basis for the API for address cleaning.
