Patent Searching and Data


Title:
METHOD FOR INPUTTING DATA OF PIPELINE NETWORK MODEL
Document Type and Number:
Japanese Patent JP2003186928
Kind Code:
A
Abstract:

To provide a system for analyzing a pipeline network based on a pipeline network model obtained by modeling a water supply pipeline network with nodes and branches, and simplifying the input and change of the data of the pipeline network model.

A computer for data input on which GIS software is mounted, a spatial data base diagram issued by a Geographical Survey Institute is picture-displayed, and nodes and branches are coordinate position-inputted on the spatial data base diagram by referring to a water supply pipeline diagram owned by a waterworks enterprise or the like, and the branches and nodes inputted on the spatial data base graphic are integrated into vector data as coordinate position data, and each node information is acquired by referring to the water supply pipeline diagram, and the symbol picture of the node is automatically inputted to the coordinate position, and the branch connecting those nodes is automatically inputted as a linear picture, and the object data of the branches and the nodes are automatically generated, and numerical data indicating each node attribute and branch attribute are inputted by using the keyboard of a computer. In this case, ground height information is acquired by overlapping an altitude map on the pipeline network model diagram, and data change is executed at a client computer side through the Internet communication or the like.
