Map Warper

Log In Create Account
Update, May 2020: Server is running out of disk space again :( I deleted around 200 maps which were untouched and unrectified to free up a bit of space. Please be prepared for downtime. Tim

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!

Upload Map!
