WebJun 5, 2024 · Modifies the coordinates of geometries in a vector layer, so that all points or vertices are snapped to the closest point of a grid. If the snapped geometry cannot be calculated (or is totally collapsed) the feature’s geometry will be cleared. Snapping can be performed on the X, Y, Z or M axis. 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 something more sophisticated would be needed for large distances or for decimal degrees. kavanaugh orthodontics
