I am having issues using ArcGIS Desktop 9.3 and the multipart to singlepart feature and then selecting by location.
Basically, I am able to run the multipart to single part feature to split up some of my polygons. I then use Select By Location, setting the parameters to within a polygon in another layer.
The problem being that it does not pick up all the features within that polygon, missing most of the ones that were originally multiparts out.
Has anyone come across anything like this before?
