I'm looking for a work around that has had me in a pickle for sometime. It involves combining a multi-part feature polygon into a single feature. Obviously if you were editing a shape you would select the features in question, start editing then "Editor" > "Merge.
Seems simple enough. However, I'm looking to do this via QGIS/ArcPy/Python (any method that will work).
Is there a way to append to a new shapefile and have it move into one feature?
See the end result example below:
