It is typically undesirable to have two areas on the same layer that overlap. This tool, located on Tools Menu > Show Map Editing Tools > Advanced Tools > Cleanup and Conversion Tools, can be used to identify any overlapping areas and correct them by removing the overlapping region from one of the areas.
To Cleanup Overlapping Areas:
1) Select this tool from the Cleanup and Conversion Tool menu.
2) Select a layer to work with. This will be the only layer that gets affected.
3) Use the cursor to drag a rectangle selecting the areas to be checked. To work on the entire layer at once draw the rectangle around the entire map.
4) If any overlapping regions are detected, Think GIS will zoom to this area and ask if the areas should be automatically fixed. Click Yes to fix the problem and move on to the next one. Or click No to leave the areas overlapping and move on to the next one. Click Cancel to stop the process and manually fix a problem
Notes:
•Area overlap is also automatically detected when drawing new areas using the Draw Area button.
•Tool use instructions will also appear in the footer of the Think GIS window in the Instructional Bar.
