Qgis calculate bearing between points
WebIs there an easy way to calculate the azimuth of the line between these points, that is, the angle to north? The naive approach would be to assume a Cartesian coordinate system (because these points are so close together) and just use sin (a) = abs (L2-L1) / sqrt (sqr (L2-L1) + sqr (B2-B1)) a = azimuth L1, L2 = longitude B1, B2 = latitude WebYou can calculate bearing in the Field Calculator in QGIS using the xat (n) yat (n) funtions. This works in UTM (metric) coordinates over small distances (hundreds of km), but …
