Parcel Data Quality

Greetings to all GIS Users!
Recently, I have worked on parcel data controlled quality and my work is to manage the quality of parcel data whether it is overlapped or gapped. Hence, Geodatabase Topology is the tool I have used.
Since the parcel multiplied, errors did appear at the same time due to the carelessness of the editors. As a result, there are thousands of overlapped and gapped polygons that I have to check by using Geodatabase Topology, and it takes weeks to accomplish this TOPOLOGY CHECKING.

My question is: Is there any way to prevent such a problem? (For Ex: To set up  rules in order not to let the polygon be drawn once it overlapped or had a gap.)

I would like to have your contribution toward the best solution.
Regards,

Hi BillFox,
Thank you for your answer. But it seemed quite far from what I referred to.
The erase tool is used to check overlapped or gap polygons once the parcel is digitized, not before digitizing.
My concept is to not let polygon be drawn once it has overlap or gap (Polygon cannot be drawn with gap or overlap, or at least there is a restriction message pops up when an error appears.)

Hi!

As shown below on the screenshot, you can add one role for overlapped polygon and another role for gapped polygon, then click next and finish. Once you successfully created the topology, go to edit tap and select your file of choice (topology file) and click error inspector and proceed further with correcting the overlapped and gaped polygons via clicking the validate tap and on the right side pressing the fix tab.

Best,

Khalil

Thank you, Khalil
This is what I am doing daily. But the point is I don't want to spend weeks inspecting errors in gaps or overlaps by using Validation (Topology Validate). Is there any prevention to such this problem? (Polygon can not be drawn once it is overlap or gap).

Hi!

The  aim of Topology is to inspect the quality of your data. The rules can be apply manually and automatically. You can apply rules when your data is in your geodatabase and dataset. To the extend of my understanding ArcGIS topology fixing error is interactive. When the errors appeared, they can be fix easily with the error inspector and fix tap.

Best,
