I have two polygon layers,
ntem, whose features overlap and intersect one another. I would like to calculate the proportion of the area of the
model polygons which fit within each
ntem polygon. Some
model features fully fit within
ntem features, others overlap multiple
ntem features. Both layers are in CRS OSGB:1936.
model feature 50209 falls partly in each of the three
ntem features 2202, 2205, 2206 and I'd eventually like to know the proportion of 50209's area in each
From initial research, I understand that the
Vector > Geoprocessing Tools > Intersect function should do what I want, however I get a completely blank layer of results when I attempt this. (Shapefile is created, empty attribute table, no features!)
Can anyone either point out if I am doing something wrong and suggest an alternative method of achieving the area proportion calculation?
