Map Grabber was written in LiveCode by Graham Samuel as an add-on to an existing simplified Geographical Information System (GIS) which runs on PCs and is designed to introduce school children to geographical mapping. Map Grabber allows the user (a pupil or a teacher) to download a very large map from a public database, and to select a smaller 'tile' of the map interactively. The tile is selected from a miniaturised version of the original large map, and then passed in its original resolution to the GIS program. Map Grabber is deliberately designed to be easy to use.
