Connect_neighbour
Network functions connect_neighbour
- connect_neighbour(point_dataitem)
- connect_neighbour(point_dataitem, relation)
The connect_neighbour(point_dataitem) results in relation for and towards the domain unit of the point_dataitem, referring to the nearest point in the point_dataitem not being the point itself.
The connect_neighbour function(point_geom, partioning) results in relation for and towards the domain unit of the point_dataitem, referring to the nearest point in the point_dataitem not being the point itself and being a point within the relation.
The connect_neighbour is a special variant of the first variant of the connect function.
The connect(point_dataitem, point_dataitem) function results in a relation to the nearest point, usually the same point. The connect_neighbour function results in the relation to the nearest point, not being the same point.
- data item point_dataitem with Point value type.
The domain unit of arguments point_dataitem and relation must match.
