How to remove duplicate features with same geometry in ArcMap?
Removing duplicate features with same geometry in ArcMap? Is it possible to uniquely identify each geometry in a feature layer? Essentially I have a polygon feature layer with many rows of data represented by the same geometry. I would like 1 row for each unique geometry.
Can you have multiple layers of the same name in ArcMap?
In ArcMap, you are allowed to have multiple layers of the same name in the table of contents. When geoprocessing scans the table of contents to build the list of layers, it doesn’t remove duplicate layer names, so the drop-down list of layers will contain all layers, regardless of whether the names are duplicated.
What happens when a layer is deleted in ArcMap?
If the session is closed, the layer is deleted. Layers created in ArcCatalog cannot be used in ArcMap, and vice versa. ArcCatalog does not display created layers, but they can be used as inputs to other geoprocessing tools in the session in which you are working. A layer or table view contains a selection, sometimes called a selection set.

How to get rid of duplicated points in arc?
I have imported a set of points into ARCmap using a kml file created in google earth. During this process, a number of the points were duplicated (see below). Is there a way to get rid of the duplicated points in arc rather than recreating the kml file which will be hugely time consuming? Use the Delete Identical tool.
