Hi all,

I have a shapefile with a bunch of features inside. some of these features overlap each other. I need to essentially do a union and maintain attributes of all features. e.g. burn in all linework and where there is overlap have the feature values for all features in overlap. How can this be done?

Figured out a process in case anyone was wondering....

1. Create a copy of the shapefile (must have Unique KEY)

2. Union this copy with the original

3. Remove all records that have the same key; Key1 = Key 2  (there will now be 2 UKEYs)

4. Remove duplicate features by area or length (hopefully unique amongst groups)

5. Erase result from original shape

6. Merge #4 with #5
