Public GIS Mapping Services

We are making a number of our GIS data layers available as public mapping services based upon ESRI’s ArcGIS Server technologies at this URL (http://public.gis.lacounty.gov/public/rest/services).  More details on each service will follow as we have the time to describe them, but generally they include GIS data that can be downloaded from this site.

We believe that for some users building applications, this can help them access our information quickly, leveraging application development interfaces like leaflet.js and ESRI’s Javascript API

For users of ArcMap, you can access the services under the “GIS Servers” tab and this URL: http://public.gis.lacounty.gov/public


Services are divided into two types.  Click on the link to access the service endpoints.

Cached Services (what are these?)

Dynamic Services (what are those?):

Important note:  These services are supported by a single mapping server, which has a fixed capacity.  We do not guarantee that the services will always be fast under heavy load.  We do manage this server within the same infrastructure as our production systems, but any issues on this server will have lower priority than for servers supporting County applications.  We do not recommend building commercial or production applications using these services.  If you have interest in accessing dedicated servers with enhanced uptime and monitoring, we may be open to you funding that service level.
