The LA County GIS Data Portal is the place to search for and download GIS data created, maintained, licensed, and stored by the County of Los Angeles. Please read the GIS Data Disclaimer before proceeding.
The County’s Enterprise GIS Steering Committee has established this site is to make high quality geographic information simple and easy to find, while providing a forum for feedback, questions, and discussion about particular data. Los Angeles County will make as much GIS data as it can, available for public use (i.e. FREE). In some cases, due to licensing restrictions, privacy concerns, or outside ownership, we are unable to do so. However, we will provide information about all of our data holdings, since there may be ways to access the data if you partner with the County.
Have fun, and think geospatially!
Sincerely,
Mark Greninger
Geographic Information Officer
County of Los Angeles

Basic instructions
Use the Search Box on the left to search for data or use the categories on the left to find data by its category. Clicking on the results will take you to detailed information about each dataset (also known as metadata).
If you have questions or comments about a particular dataset, please use the comment areas below the descriptions – the data owner will get the comment and reply, and since other people will likely have the same question, your question will probably help someone else, and we encourage a conversation about each dataset. You can also register to receive updates when new data is posted, and when data has been updated.
