用法例句

Polygon simplification in scaleless GIS (geographic information system) is based on the line generalization of polygon arcs, but there may be topological errors in output data resulting from the direct line generalization of polygon s arcs, and the major representation of the error is the intersection of the simplified polygon s arcs.
