Abstract:

A methodology was developed for testing and evaluation of automated cartographic editing functions provided by cartographic data capture systems. Editing functions include gap closure, spike removal, snow removal, node snapping, centerline adjustment, etc.. These functions are often implemented in three modes automatic, computer-assisted and manual. The Battelle benchmark testing method focuses on automated editing. The testing and evaluation method consits of a single analog film positive edit test sheet and a series of test procedures. The edit test sheet portrays a column of cartographic patterns with anomalous versions of these cartographic geometries arrayed in rows to their right. Different lineweights and pattern orientations are also utilized. The full range of editing functions are applied to the data to test for rates of success and sensitivity to geometry, lineweight and orientation.
