Cleaning up Maps

Sometimes when you are digitizing, you may unintentionally digitize

the same object twice. Or you might draw lines that are too long

(overshoots) or too short (undershoots). Before you can create a

topology to perform map analysis, you must perform a map cleanup.

A map cleanup identifies the problem areas in your drawing so you

can go back and fix them. Or, you can choose to have the Cleanup

command fix the problems for you automatically.

Along with deleting duplicate objects and shortening and lengthening

lines, the Cleanup command also locates (and breaks) lines that cross.

This makes digitizing easier, because you do not have to draw discrete

lines for every object that you want to represent, such as parcels.
