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!
