Update July 2020: Ran out of disk space. Maps older than 2 years will need re-warping to work. Downtime will happen again.

Overview

Find maps and other imagery, upload, and rectify against a real map.

You can then download and use the rectified map in your mapping applications.

Just sign up and you can start uploading and get warping!
