摘要： PROBLEM TO BE SOLVED: To obtain a three-dimensional digitization model of each tree from three-dimensional aerial survey data.
SOLUTION: A three-dimensional coordinate calculation device 32 calculates DSM data indicating a three-dimensional position of a tree on the ground and DTM data indicating a three-dimensional position of the ground from aerial survey data and stores the data in a storage device 34. A branch end extracting device 36 extracts a branch end 34c from the DSM data. A tree top extracting device 38 extracts a tree top 34c from the branch end 34c. A tree height calculation device 40 calculates the tree height of a tree top 34d from the tree top 34d and the DTM data. A tree crown extracting device 42 extracts a tree crown of each tree top from the DSM data and the tree top extracted by the tree top extracting device 38.

摘要： PROBLEM TO BE SOLVED: To provide a method, device and program for extracting a cave-in area based on three-dimensional geographical information. SOLUTION: A target region is three-dimensionally measured by a laser measurement device 12 of a helicopter 10. A three-dimensional coordinate calculation device 32 generates DSM mesh data and DTM mesh data from the measurement result, and stores those data in a storage device 34. A bare ground extraction device 36 extracts a bare ground from the DSM mesh data and the DTM mesh data. An inclined ground extraction device 38 extracts an inclined ground from the DTM mesh data. A cave-in area extraction device 40 extracts a cave-in area from the DTM mesh data. An area filtering device 42 extracts a region having a fixed area or more from results refined by those devices.

摘要： PROBLEM TO BE SOLVED: To provide a geographical data editing system capable of easily plotting a very small design at a state with attractive appearance and visibility when the very small design to be specified by a label of a certain plane entity in a certain area on a map defined by the plane entity is distributed and plotted according to a prescribed pattern. SOLUTION: The geographical data editing system to automatically plot a map by a computer based on entities of points, lines and planes to be included in geographical data and their labels is provided with a function to calculate pieces of size data corresponding to area of each region based on each plane entity and to increase arrangement density of the very small designs to be plotted in each region as the area becomes larger based on the pieces of size data.
