This algorithm calculates the rotation required to align point features with their nearest feature from another reference layer. A new field is added to the output layer which is filled with the angle (in degrees, clockwise) to the nearest reference feature.
Optionally, the output layer's symbology can be set to automatically use the calculated rotation field to rotate marker symbols.
If desired, a maximum distance to use when aligning points can be set to avoid aligning isolated points to distant features.
An example use case for this is the aligning of building point symbols to follow the nearest road direction by using a data defined rotation value generated by this algorithm.
