Caltrans Earth Overview

Notice to users

The map display in Caltrans Earth uses the Google Earth Application Program Interface (API) and Google Earth Plug-In software. Google announced they will be retiring their API and Plug-In software on December 12, 2015. Google stated that these components were developed on an older technology (NPAPI) which is determined to be a security risk. There are no announcements from Google about continuing these products and services using other technology platforms.

In the meantime, as Google Chrome, Internet Explorer and Mozilla Firefox internet browsers continue releasing their own software upgrades, users are beginning to experience diminishing support for the Google technology components of Caltrans Earth.

Currently we are determining the future direction and evolution of Caltrans Earth as a web-based spatial data access solution. The Caltrans Earth website (earth.dot.ca.gov) will be updated as events occur.

For the time being, we recommend using Caltrans Earth in Internet Explorer 11
