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
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.
You can perform the following
- 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
To edit topologies, use the topology editing
. Drawing Cleanup
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.
