I have a polygon (.shp) and a shapefile (.shp) and I would need to calculate the percentage of the polygon overlapping with the shapefile.
Someone suggested me to ude the Intersect function, but I can't figure out how.
Could someone tell me how to proceed, step by step?
thank you in advance!
The ideal tool would be Identity, but it's only available with advanced license.
Alternatively, first calculate the original area into a new field in your polygon file. Intersect it with the other file. This will leave you with a polygon showing only the overlap between the two files, but the attribute table will still hold the original area value. Calculate the new area into a new field. Calculate percent between original and new area.
I used identity (but I also tried with intersect and it's the same).
Instead of getting a new polygon with its area in the attribute table, I get this:
I need to know the area of the intersect...
I am old fashion.... when I do overlapping percentages .. I use a semi-manual arithmatic process..... described here. This does work, although it does take time to work through the process.
Logic also works for polygons in one layer.
