A lighting control system and method for association of nodes in a multi-node network. The system includes a number of lighting nodes forming a multi-node network, each lighting node including a light source, a controller connected to the light source, and communication means connected to the controller. The lighting control system further includes a memory component adapted to store information relating to at least one group of interrelated coordinates defined in a geographical coordinate system and a processing component in communication with the lighting nodes and adapted to automatically associate at least one lighting node with the at least one group on the basis of the geographical location of said at least one lighting node.
