The map units used by this map (meters, feet, degrees, and so on). The map's map units can be retrieved by calling the mapUnits() method. An extent, which is the area of the map currently shown within the canvas
st_to_meters() - Convert a length to meters. st_geodesic_bearing() - Returns the geodesic azimuth starting from the first coordinate in the direction of the second coordinate. st_geodesic_distance() - Returns the geodesic distance in meters between two coordinates or two geometry points. ...
but in meters when feet would be expected (even when the proper configurations are in feet in general options/project properties). I have no idea if this is a regression since a previous QGIS version. If yes this should be tagged as blocker. It should be checked also if the same happens...
feet, meters, kilometers defined by WGS 84 great circle distance) rather than map units. The haversine formula is used to approximate meaningful radius distances independent of the original projection. While this may introduce some deviation from the original CRS, buffering is assumed in practice to...
