I'm comparing raster and vector distance zones.
So I created a line, calculated the Euclidean distance, and reclassified the raster to two zones: from 0-10m and 10-20m. To compare it with vector distance, I created a Multiple Ring Buffer with the same line and the same two zones, 0-10m and 10-20m.
When I'm calculating the area, for example for the 0-10m zone, the (vector) buffer has an area of 1475 m² while the Euclidean distance raster for the same zone has an area of 1493 m²!
Can someone please explain why those two values differ?
