A method and system are presented which will detect combinations of user touches on a touch screen device as nodes, and will create points, lines, shapes, areas and windows from these nodes. Where the device has a communications capability, the locally defined points, lines, shapes, areas and windows can be shared with remote users and databases, and similarly points, lines, shapes, areas and windows created by others can be viewed on a local display. The method and system are of particular benefit to drawing applications, windows definition on touch screen devices, real estate management, navigation, and exploitation of mapping resources.
