Examples of past data analysis and display requests include:

Data Linkage Services

CEHTP also conducts “record-level spatial linkage” with data related to environmental hazards, such as traffic and agricultural pesticide data.  This means that we use a geographic location to link any dataset that contains a geographic component (such as addresses or geographic polygons) with hazard datasets (such as those from CalTrans or the Department of Pesticide Regulation) to calculate a variety of hazard metrics for each record.  The user can define a number of linkage parameters, including the area to be analyzed around each location. 

Examples of past data linkage requests include:

  • Linking pesticide use data with maternal residence to study birth defects
  • Linking traffic density with patient addresses to study asthma morbidity

For More Information

We provide data services on a case-by-case basis dependent on staff availability.  Fees may be applied to some services.   Please contact CEHTP for more information or to make a request.
