I am new to a company that makes use of a rather large database of point data. For whatever reason, the woman who was here before me made a huge amount of duplicate points - the attributes may be a little different but the coordinates are the same.
I've found that I can remove the points either in QGIS using the mmqgis plugin, or in ArcMap using the "delete identical" tool. However, when I use either method, I have noticed that there are some points that are removed completely. For most, it leaves one point but I have found a few that are completely gone.
Do any of you know of a method to add unique features to an attribute table?
I'm thinking that I can compare the original table to the "cleaned" one and add the missing points back. Loo
