Abstract

A computer program, named MAPSEE, for interpreting maps sketched freehand on a graphical data tablet is described . The emphasis in the program is on discovering cues that invoke descriptive models which capture the requisite cartographic and geographic knowledge. A model interprets ambiguously the local environment of a cue. By resolving these interpretations using a new network consistency algorithm for n-ary relations , MAPSEE achieves an interpretation of the map. It is demonstrated that this approach can be made viable even though the map cannot initially be properly segmented. A thoroughly conservative, initial , partial segmentation is described . The effects of its necessary deficiencies on the interpretation process are shown. The ways in which the interpretation can refine the segmentation are indicated .
