Hi all. I may well be tired, but I cannot understand why: CREATE TABLE clip2 AS SELECT rid, ST_Clip(rast, 1,ST_Buffer(ST_Centroid(ST_Envelope (rast)),5000)) AS rast from hdr WHERE rid = 4;
does not result in a circle, but in a square, contained in the buffer but smaller. See attached pictures, with the buffer in green, and the clipped raster inside. Any hint?
