Title:
衛星画像を利用した高度視界情報提供システムとその方法及び飛行障害認識システムとその方法
Document Type and Number:
Japanese Patent JP4174559
Kind Code:
B2
Abstract:
A satellite image analysis and processing apparatus includes a DEM extraction unit for extracting digital elevation model information having topography data and steeple-shaped building data; a topography situation recognition unit for discriminating a kind of topography and recognizing a topographic situation from the topography data of the digital elevation model information; a steeple-shaped building recognition unit for recognizing shape and location information of steeple-shaped buildings from the steeple-shaped building data of the digital elevation model information; a time series recognition unit for recognizing a change with time; and an altitude visibility information preservation unit for preserving altitude visibility information obtained by combining information acquired by the topography situation recognition unit, information acquired by the steeple-shaped building recognition unit, and information acquired by the time series recognition unit in an altitude visibility information database provided in the altitude visibility information preservation apparatus.
