Hello,
Do you have a technology preference for developing this program? If not, I can develop a simple utility in .NET that can parse a KML file and remove the duplicates. Also, do you want a UI that for example allows you to select the KML, press a button to start the process and displays feedback such as number of duplicate placemarks found and removed, current status of the process, etc? Or do you want something that runs in the background without the need for user intervention and maybe monitors a folder for any new KML file that may be dropped into it, parses and removes duplicates from those files and perhaps saves a report to a text file? Please advise.
Thank you,
Hatim
