Abstract:Based on the geographic information managed by tables and rows similar to special database, we propose a data tracing approach for navigation digital map production. The creation and management of data tracing is discussed, and several methods of its control and utilization is present as well. Data tracing can not only solve the opacity of indoor and field information change, but also provide direct precondition for the creation of data difference and versions. It also can provide undo and redo function in ...
Keywords:data trace  versions difference  undo redo
