Topographic information on connection graph

Description

The data are topographic information( elevations and relative distances) of connection graph on a sewer catchment area. Node 0~65: sewer discharge node, Node 66~121: candidate Steiner node, Node 122~129: sewer sink node . The Steiner nodes serve as optional nodes to link each sewer discharge node and flow to sinks on an optimal sewer layout. The optimization mode connects all sewer discharge nodes by Steiner nodes to generate a least-cost sewer layout system.
