Here are the step-by-step directions for repairing the overlaps found in the sample parcels.shp data:
- Toggle the editing option on for the parcels layer and select the polygon to edit with the Select Feature by Rectangle tool (
 ). Each vertex will be displayed as a red graphic X. - The Vertex tool (
) will be used to move the leftmost parcel and eliminate the overlap. It allows individual vertices to be moved. - Click on one of the parcel corners, and the vertices will appear as red boxes.
- Click on the lower-left vertex of the right-hand side parcel to select it. It will turn blue.
- Drag the selected vertex until it snaps to the boundary of the parcel it is overlapping. A blue line will appear showing the location of the virtual polygon boundary as you edit it, as shown in the following diagram:
This is the vertex of the right-hand overlapping...
