OCAD Sketch complements the desktop version of OCAD. It is designed for mapping in the field - both for new maps as well as revisions, feedback from course planners or map reviewers. Drawing pen and eraser enable fast and ergonomic sketching. GPS routes can be tracked and the compass can be used to adjust the map orientation. Map projects are transferred from desktop version of OCAD to the OCAD Sketch App and can be sent back after mapping.
