Abstract:
1. A computer based method for editing cartographic data, the method comprising: retrieving, in a computer system, cartographic source data from a first record set and displaying at least one feature of the source data in a display device; based on a computer input by a user selecting a feature in the display device, identifying, in the computer system, cartographic source data corresponding to the selected feature; responsive to a computer input by the user instance editting the selected feature in the display device, creating cartographic edit data representing the user's instance edit of the feature without modifying the retrieved cartographic source data; associating the cartographic edit data, representing the user's instance edit of the feature, with the unmodified cartographic source data for the feature; storing the associated cartographic edit data within a second record set that is editable by further user instance edits of features; and creating, in the computer system, an output record set for display on the display device by merging the unmodified cartographic source data and the associated cartographic edit data without modifying the unmodified cartographic source data.
