I have an idea of what I want to do but I don't know yet what tools will bring me there.
I have administrative boundaries in one layer and coastline in another layer. The coastline is categorized in different classes. What I want to find out is how much of each category falls into each administrative boundary. So the outcome would be percentages of the administrative unit's coastline for each class. So say the coastline from unit 1 is 40% class A, 50% class B and 10% class C. Unfortunately, the two shapefiles do not match up exactly because one of them does not have a spatial reference...? (I work with ArcMAP10)
Any hints and ideas what tool will bring me there? Any help is greatly appreciated Sandra
