CALCULATION SYSTEM OF POSSIBLE HEIGHT USING A DIGITAL TOPOGRAPHICAL MAP AND A DIGITAL CADASTRAL MAP FOR CONSTRUCTION

摘要

PURPOSE: A building height calculation system which uses digital spatial information construction database is provided to calculate construction available height by using digital spatial information construction database. CONSTITUTION: A dividing unit(20) generates an overlapped map by overlapping a digital topographical map. The dividing unit displays a boundary line in the overlapped map, displays a boundary line, and extracts a coordinate value of the boundary line. A calculating unit(30) calculates the width of a road by using coordinate value of the boundary line and calculates construction available height.
