Caltrans Earth (CT Earth) visually brings together the vast amount of transportation and land use information compiled through the California Interregional Blueprint. CT Earth helps Caltrans, other state agencies, and the general public to make better decisions about our transportation system.

CT Earth, developed by Google, is a web based, California-focused, virtual 3D globe. It integrates and shares regional and statewide current and planned multi-modal transportation data and is easily accessible from a web browser, mobile clients, and web GIS services. CT Earth provides real-time transportation system data.

CT Earth offers an opportunity for everyone to view information in all phases of projects, including environmental planning, design, construction, and operations. This information includes state highways, rail, transit facilities, environmental resources, current and planned projects, and more.
