The OCAD App complements the desktop version of OCAD. It is designed for mapping in the field - new mapping projects as well as map revisions, course planner feedback or map reviews. The app tools are designed for fast and ergonomic mapping and sketching. GPS routes can be tracked and the compass can be used to adjust the map orientation. Map projects are transferred from the desktop version of OCAD to the OCAD App and synchronized back after mapping.
