While rectifying maps, WorldMap WARP also geo-references the uploaded map on an online modern map, so that physical landmarks(coasts, streets, geological features, etc.) will lay ontop of each other. WorldMap WARP is an online tool to rectify an uploaded map so that it may fit exactly(or more closely) on a modern precise map, such as a Google map. Incredibly simple to use, but hard to get precision.Ĭannot warp maps, can only resize and rotate maps Because of this, it is very difficult to get a perfect match unless you're mapping a small area and the map is drawn to scale. Unlike the other tools in this section there is no stretching involved. It is simply laying the map image over a section of the globe on Google Earth, then resizing the map image so that it lines up with the features on the globe. Putting a historical maps on Google Earth is very simple. The resulting warped map should then be easier to work on using that application. In order to counteract this problem, a number of tools exist that allow you to warp (also known as rectify or georeference ) a map, so that it will fit on a Google Map or another mapping applications's interface. may not exactly match up between any two maps.
