I am first and foremost an ecologist working to promote the integrity, stability and beauty of the biotic community. I enjoy finding solutions to problems on this site that I otherwise would not have exposure to in my day-to-day work.

Specialties: Remote sensing, GIS, spatial statistics, big data, wildlife conservation, and landscape ecology. My work focuses mainly on multispectral and Lidar remote sensing for assessing vegetation structure and composition.

Although this is in good humor, it does not provide an answer to the question. Please elaborate...

comment How to clean up a polygon by removing vertices and lines within?
From a GIS standpoint, "deleting the holes" is another way of saying "merging the smaller polygons with the larger polygons". Could you please elaborate on what the problem is?

@Renée Then you will want to use the Eliminate tool: resources.arcgis.com/en/help/main/10.2/index.html#//…

comment How to clean up a polygon by removing vertices and lines within?
A polygon shapefile can only have polygons--points and lines are not allowed. The approach I highlighted selects the polygons you want and creates a new shapefile based on that (disregarding all of the slivers/small polygons). Sounds like you may need to use "Check/Repair Geometry" if you have broken geometry. Otherwise, the "Eliminate" tool may work for you by merging the small polygons with larger polygons.

Welcome to the site Soha. I have placed this question on hold until you can focus the question and provide information on what you have tried already and where the user documentation has failed you. Please take the tour to get up-to-speed on how the QA format works on GIS Stack Exchange: gis.stackexchange.com/tour

comment Is there a way to execute tools based on the names of feature classes or raster names?
Could you please supply more information on your data structure? I am having a difficult time envisioning what you are trying to do. Why would you require an automated approach on this as opposed to an out-of-the-box approach?

It would be helpful to show an example of the data you are working with as well as the intended output.
