Hi all
I'm trying to find a way to add field names to each feature class in a geodatabase with Python.
My pseudo-code so far is:
1) Buffer points
2) Add field to each featureclass with name that represents the featureclass.
3) Calculate field, entering the value Y in each field.
4) Perform Spatial join on, the Y value will appear in each record where the point intersects featureclasses.
5) Delete all unwanted fields so that I am left with the point identifier, and each column containing Y's
6) Output to .csv
I can do the spatial join and have that running. At the moment I have no way of determining the unique field name for each featureclass.
So I would like the field names to be meaningful, (not just Field1). I am using about 40 features which represent a variety of environmental considerations. For example, for a file representing wetlands I would like a field called Wetland. I have looked at TKInter which I've read can be used to enter text dynamically and then used as a variable, which I think would work well. It would ensure that I know what each field name means. I just don't seem to be able to use the input text as a variable.
The TKInter code is (I am open to other suggestions of course):
