Description
Summary:Light Detection and Ranging (LiDAR) is a technology that has been used for years with the variety of applications including the production of digital terrain models (DTMs), and high-accuracy mapping. LiDAR offers a very detailed collection of 3-D point clouds of the earth surface which can be used in generating orthophotos. Traditional orthophoto production based on the DTM has to accept that buildings and other objects above ground are not correctly placed in the orthophoto. These deficiencies can be overcome by simply taking the digital surface model (DSM) into account. In this paper, the literature reviews on the quality of true orthophoto production by fusing the digital aerial photos and LiDAR DSM done by former researchers are investigated. The results of the true orthophoto will be assessed by comparing the output and achievement gained by the researchers on the same field of study.
