APPARATUS FOR MULTIPLE DETECTING ORTHOMETRIC HEIGHT CORRECTION POINT

摘要

PURPOSE: A device for multiple-detecting an orthometric height correction point is provided to rapidly and efficiently detect an optimum orthometric height correction point with a satisfied gradient. CONSTITUTION: A device for multiple-detecting an orthometric height correction point comprises a node generating unit(21), a search area setting unit(22), an orthometric height candidate setting unit(23), and an orthometric height correction point detecting unit(24). The node generating unit sets multiple nodes by using the boundary line and points of a building as a starting point. The search area setting unit is connected to the node generating unit. The orthometric height candidate setting unit is connected to the search area setting unit and sets one or more first circular candidate sources with a second radius. The orthometric height correction point detecting unit is connected to the orthometric height candidate setting unit.
