What is it?

It's a free to use, open source map warper / map georectifier, and image georeferencer tool. This project is supported by Entropy Free and the New York Public Library.

Note: This has been migrated from it's old home at warper.geothings.net . It's now running much faster and previous limits about file sizes and image dimensions have been raised much higher!

Mail me at tim@geothings.net for more information!
