Data Services & Requests


The SCAG Data Services Program was initiated and organized starting in the late 1980s with the goal of being the preeminent source of information for the southern California region. The purpose of the program is to derive and promote a model policy for distributing geospatial data and other information developed and maintained at SCAG. We believe so strongly in providing this service to stakeholders that we have incorporated this philosophy into our Ten Year Strategic Plan.

Our services are available to government agencies and private businesses without any fees. Our information is used by local government, public agencies, consultants, academia, students and the general public. Our information is designed for use in plans, studies, analyses, and presentations.

When it comes to researching and analyzing, accuracy of the data is considered as one of the main components. This particular program is designed to organize and maintain our datasets in a way that it helps interested parties to efficiently utilize the data.

Our program goals are:
  • Users of geographic information and data will gain better access to needed data

  • Local governments and public agencies will partner with SCAG on data standardization

  • Local governments will find more, and diversified, users for their data

  • Local governments and SCAG will realize cost savings through data sharing and through the establishment of consortiums when feasible

  • Data maintenance, update, and metadata documentation will become accepted as part of the normal data distribution business process

  • The maintenance of this program is spearheaded through the Research and Analysis department under the Land Use and Environmental Planning division at SCAG.
