Overview of Cleaning Up Maps
Use Drawing Cleanup to correct common geometry errors resulting from
surveying, digitizing, and scanning before you define a topology, perform a
map analysis, plot a map, or export to a geospatial data format.
You can also remove unnecessary detail from complex maps.
Example: You digitized paper maps and now some street intersections do not
align correctly. You want clean the maps before you create a topology.
NOTE This functionality is for drawing objects only. There is no equivalent for
geospatial feature data.
You can perform the following cleanup actions:
■ delete duplicate objects
■ erase short objects
■ break crossing objects
■ extend undershoots
■ extend to apparent intersections
■ snap clustered nodes
■ dissolve pseudo nodes
■ erase dangling objects (overshoots)
■ simplify objects
■ delete zero-length objects
■ weed 3D polyline vertices
WARNING To edit topologies, use the topology editing commands (page 851).
Drawing Cleanup can make a topology invalid. In addition, when a cleanup action
creates a new object or breaks an object into multiple segments, classification
information remains with the segment that contains the start point of the original
object. Classify other segments manually.
