ROAD LEDGER CREATING SYSTEM AND ROAD LEDGER CREATING PROGRAM |
摘要 |
PROBLEM TO BE SOLVED: To efficiently process and automate electronic processing operation by effectively utilizing minimum data obtained in the on-site survey and existing drawing data. SOLUTION: Feature points of a road structure are surveyed to obtain digital plane-table data 1 consisting of a group of coordinate data of each feature point. A vetor data conversion means 6 connects the groups of coordinate data representing the outline of road structure mutually with line segments. A polygon data conversion means 7 divides each road structure by a prescribed unit and expresses the graphic of the road structure in a set of polygon data. An attribute data adding means 8 generates a database of each polygon data added with attribute data representing the quality of the road structure. COPYRIGHT: (C)2003,JPO
