Map Warper

Log In Create Account
To help free up space, I removed a few files, so you may need to re-rectify (and/or crop) a map if you can't see it in the maps Preview tab.
Also a few maps which were old, untouched and never rectified, with no points on them and without belonging to a mosaic were removed, so you might need to re-upload.

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!

What is it?

It's a free to use, open source map warper / map georectifier, and image georeferencer tool for individuals and small groups. Developed, hosted and maintained by Tim Waters. If you like this project, please consider donating to keep the project going.
