New Feature: 3D

Looking at a route and need to visualize in a different way? Searching for a lost hiker and want to view the terrain in the search area? Change your perspective with CalTopo 3D.
After a lot of behind the scenes work, we are so happy to bring 3D to CalTopo web and mobile! This is a feature we are all incredibly excited about, and from feature requests over the years we know you will be too.

This isn’t just any old 3D map though. With CalTopo’s new 3D you can accomplish everything you are used to getting done on CalTopo in 2D.
- View all of our existing layers in either 2D or 3D.
- Planning a spring ski line? Stack sentinel weekly on top of Mapbuilder topo to view the map and snow coverage while visualizing your line.
- Climbing Mt. Rainer? View the peak in 3D and adjust your tentative route to avoid large crevasse fields visible on shaded relief. Seriously, volcanoes look so cool in 3D.
- Visualize terrain before sending a search team into the field. Create search areas based on terrain, or rank likely and unlikely routes taken by viewing a 3 dimensional representation of the area.
The use cases are unlimited. Leave a comment below on how 3D will change your mapping!
To enable 3D, click or tap the “3D” icon on the upper left side of the map viewer on both web and the mobile app. Controls will differ slightly between the versions. On the web, use the controls as follows when in 3D mode (these can be brought up at any time by clicking “3D Controls” at the bottom of the map viewer).

On mobile all perspective changes are done using your fingers. Drag two fingers vertically to change the pitch. Drag two fingers in a spinning motion to rotate the map, and drag one finger to move your location on the map (as normal). You can toggle back to 2D in the upper left corner.
For more information on using 3D in CalTopo, visit the 3D page in our user guide.
To use 3D on mobile, ensure you have the most recent app version downloaded (1.13.6 and later). To check for updates visit the app store by following this link: caltopo.com/appstore.
3D will be available to all CalTopo users (free and paid) through the end of 2024. Give it a try, tell us what you think! Starting January 1st, 3D will be available to users with a pro, desktop or team subscription. You can view our subscription levels and upgrade at caltopo.com/join.
