Hello, is there a "good way" to determine if the planar or geodesic method should be used (for area calculation), when working with UTM ?
e.g: I am working with WGS 1984 UTM (Zone Nord) data and when calculating polygons areas, in square meter, I have the below results
# At buildings level (~1:2,000) the geodesic method produce a slightly larger area (1 feature)
# City level (~1:12:000) the planar method produce slightly larger areas (multiple features)
Thank you!
