I moved a lot of Polygons while editing (now it has weird gaps and overlaps)

Question

I have one giant polygon then I used the edit tool to slice and divide the areas to make different land types now it has weird gaps and overlands cause I accidentally moved a lot of polygons. What can I do to make it all fit? Thank you

There is this thing called "topology" that is used for this.

Basically, you

* Create a geodatabase.
* Create a new feature dataset in the geodatabase.
* Copy or move the polygons as a feature class inside the feature dataset.
* In that feature dataset, alongside the polygon feature class, create a new topology.
* Onclude the feature dataset in it.
* You then add rules for the dataset such as Must NotOverlap and Must not have gaps.
* Then you validate it.
* The result show you highlighted gaps and overlaps.

There are topology tools that allow you to decide what to do with the overlaps or gaps: that is to assign them to one side or the other of the overlap or gap.

Hope this makes sense and helps.
