About CalTopo

CalTopo is a web mapping tool for planning and sharing backcountry trips, aimed at individuals and at teams such as search-and-rescue groups. Users can research a route, add layers, record tracks, print maps and take them along on a mobile device. It is designed for backcountry terrain and also works for everyday maps closer to home.

The service stands out for its layers and collaboration. Available layers include slope angle shading, snow depth from SNOTEL stations, satellite imagery, water gauge data for streams and reservoirs, elevation-specific weather forecasts and public land boundaries. Multiple people can edit the same map at the same time with real-time updates, and location sharing, GPS device connections and offline map downloads are supported. CalTopo is a hosted commercial service with individual and group pricing.
