A method and system are presented which will detect combinations of user touches on a touch screen device as nodes, and will create points of definition, lines, routes and corridors from these nodes. Where the device has a communications capability, the locally defined points of definition, routes and corridors can be shared with remote users and databases, and similar entities created by remote users can be viewed on a local display. The method and system are of particular benefit to navigation applications, map customization on touch screen devices, real estate management, scientific measurement, and geographic information systems.
