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?

From what you are explaining the Euclidean Distance would be (a) The buffers would be (b) So the differences would be in the corners (c)
