Network functions
Network functions are used to build and calculate with network topologies like connect or impedance
- first_node - a point data item with the coordinates of the first point of an arc or polygon
- last_node - a point data item with the coordinates of the last point of an arc or polygon
- connect - creates the nearest point on an arc/polygon data item from a point data item or finds the nearest point in a point data item from another point data item. Includes an optional maximum geographic search radius
- connect_eq - creates the nearest point on an arc/polygon data item from a point data item if the values of two data items match
- connect_ne - creates the nearest point on an arc/polygon data item from a point data item if the values of two data items do not match
- connect_neighbour - a relation to the nearest point in the same point data item, not being the point itself
- connect_info - information for each point on the connection to an arc/polygon data item, as made by the connect function
- connect_info_eq - information for each point on the connection to an arc/polygon data item, as made by the connect_eq function
- connect_info_ne - information for each point on the connection to an arc/polygon data item, as made by the connect_ne function
- dist_info - variant of connect_info to only show the distance between arc/polylgon data item and points
- connected_parts - the connected (sub)networks that exist in a set of links
- capacitated_connect - finds the nearest point in a point data item from another point data item with a capacity constraint
- Impedance general (formerly known as Dijkstra) - a description of the dijkstra algorithm
- Impedance key entities - a description on nodes and links
- Impedance functions - how to apply the impedance function
- Impedance options - optional parameters of the impedance function
- Impedance warning - warning if the impedance is applied with very large datasets
- Impedance interaction potential - additional information on the concept of interaction potential
- Impedance additional -some additional information on impedance functions
- Impedance future - our ideas on potential future impedance functionality
- Impedance links - interesting links
- Impedance example origin to nearest destination - an example of how to apply the impedance function to calculate the distances of a point set to the nearest point in another point set
- trace_back - the amount of flow for each link in the network.
- service_area - the relation to the nearest destination node for each node in the node set.
