A QGIS plugin that performs a nearest neighbour join on two vector layers.
For each feature of the input layer, the nearest feature of the join layer is found, and the distance between the two features is calculated.
The result of the operation is a new vector layer. A feature in the result layer will have the geometry and attributes of one of the features in the input layer plus the attributes of the nearest feature in the join layer. In addition, a new attribute is added that contains the distance between the two neighbouring features.
