Hi everyone. I apologize if this has been asked before but I would just like to clarify if this is how the buffer algorithm in QGIS should function.
*Issue:* The actual distance from the input layer to the buffer polygon created by the Buffer processing tool (and v.buffer) is not equal (only around 80%) to the Distance parameter provided in the said tool. *Example:* My coordinate reference system is WGS84/UTM Zone 51N (EPSG: 32651). I create a 100m buffer around a point but when I measure the resulting circle, its edge is only ~80m from the point (see buffer-point and buffer-point-distance below). buffer-point.png <https://drive.google.com/file/d/1SAptLcRKnGVc8zyESkl-sJZ23a5OWEsy/view?usp=drive_web> buffer-point-distance.png <https://drive.google.com/file/d/1aQ0mfadGnEzISkPnu-GGX9SUu1GXhGMs/view?usp=drive_web> I create a 50m buffer around a line but when I measure the resulting buffer, its edge is only ~40m from the line (see line-buffer and line-buffer-distance below). line-buffer.png <https://drive.google.com/file/d/11cNTRNbHxB3cFCaZEhXDWqKYEdWJX31K/view?usp=drive_web> line-buffer-distance.png <https://drive.google.com/file/d/1PGRabSqF-zrOCpAboncQ_yQxx_0ulByN/view?usp=drive_web> Clarifications will be much appreciated. Maybe I just missed some part of the documentation. Thank you. Sincerely, Ben Hur -- --- *Ben Hur S. Pintor* bnhr.xyz Consultancy · Training & Support · Development & Innovation
