Recently, the tree in the river causes various problems in on the flood control and the river management by grows up and making to the forest. Therefore, it is necessary to manage and deforest of the tree in the river. However, it is a difficult in a current search procedure to decide the priority level of deforestation. Now, it is requested to understand widely and quantitatively of riverine vegetation state from the management of the tree in the river.
Then, this study aimed to understand Riverine Vegetation Characteristic of Perpendicular Distribution by analyzing the three-dimensional distribution of Riverine Vegetation with Using Airborne Laser Scanner and Aerial Photographs Data.
As a result, it has been understood that vegetation grows thickly easily from the waterside to the embankment side, and the tree grows up easily to the higher ground level, and we have to observe the deforestation land continuously so that the obstruction of the flow of the river should not occur again.
In those results, we hope to understand high accuracy of perpendicular distribution with using airborne laser scanner and ground laser scanner
