I have a surveyor working on a survey. Every evening, we convert his survey file to a shape file. Next day, he goes out and works on the same survey, he comes in and I convert it to a shape file. Is there a way to combine these multiple files into one shape file, but not have any duplicate data? If he surveys points 1 thru 50 on the first day, I make a shape file. Next day, the file still has points 1 thru 50, but adds 51 thru 100. They way I have been doing it, is to just keep replaceing the file with the newest file, but I am to the point where I need to be adding data to the shape files, and if I edit the shape files in arcmap, I can't replace it with what the surveyors do.
As I re-read this, it seems like rambling! Bottom line is I need to join shape files with no duplicate data.
Thanks for reading.
