摘要:In order to estimate proper current land price, various factors such as environment, communication, regulation of land use and so on are established by local government. Road slope is one of the land price factors for land form, and land price is corrected by road slope aspect based on road slope for the north. For example, road slope aspect is corrected so that land price face to northern slope road is able to become cheaper, or land price face to south slope road is able to become higher. Therefore, road slope aspect correction is one of important factors for local government where locate undulate area. However, the road slope aspect is appraised by primitive method with great time and labor, such as using contour map or field investigation using surveyor's level.On the other hand, airborne laser surveying has been receiving more attention as a useful tool for real-time 3D data acquisition, and many applications such as city modeling, DTM generation, monitoring electrical power lines and detection of forest areas were proposed. Therefore, it is expected that DEM which is generated by airborne laser surveying is enormously contribute to generate road slope map so that land price estimation can be performed effectively.With these motives, generation of road slope map and visualization of road slope aspect for fixed assets appraisal of lands using DEM were investigated in this paper
