You can display your own maps against a real map (OpenStreetMap) for free, and make them available on the Web for anyone in the world. Maps such as handwritten or old ones can be used as well as modern standardized ones.

Uploaded maps are rectified (warped) against a real map by adding control points, which specify geographical positions.

Once published, these maps are available to export in image or map formats.

About Map Warper

This tool is a Japanese instance of Map Warper, an open source georeferencing application. Map Warper is developed by Tim Waters, who is a geospatial developer and consultant, in response to the promotion of digital publishing of maps in Western countries and the increasing need for georeferncing software. We localize it and provide this Japanese version of Map Warper here, to promote free web-based georeferencing tools in Japan, supported by JSPS KAKENHI (16H01965, 17H06186).
