SRTM DEM Correction in Vegetated Mountain Areas through the Integration of Spaceborne LiDAR, Airborne LiDAR, and Optical Imagery
The Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM) is one of the most complete and frequently used global-scale DEM products in various applications. However, previous studies have shown that the SRTM DEM is systematically higher than the actual land surface in vegetated mountain areas. The objective of this study is to propose a procedure to calibrate the SRTM DEM over l...
متن کاملAirborne and Spaceborne Lidar
The evolution of lidar, from those early ground-based measurements to our first long-duration spaceborne experiments, is schematically represented in Fig. 13.1. It depicts the first lidars in the 1960s as ground-based, followed by systems first flown in 1969 on small aircraft, and followed in the late 1970s by lidars flown on large aircraft capable of long-range measurements. Starting in 1979, ...
متن کاملDigital Terrain Model on Vegetated Areas: Joint Use of Airborne Lidar Data and Optical Images
Airborne Lidar system provides the Earth’s topography as 3D point clouds. Many algorithms have been implemented to sort out the automatic classification problem as well as the Digital Terrain Model generation (DTM). This is mainly due to the various aspects of landscapes within a global survey which can include urban, forested or mountainous areas. This paper is focused on the generation of DTM...
متن کاملDem Generation from Airborne Lidar Data
Airborne Lidar (light detection and ranging) sensors provide dense height information of large areas in an efficient manner. But for the production of digital elevation model (DEM) from the point cloud, the filtering of the point cloud should be carried out in order to remove points representing surface of non-ground objects. According to the deficiencies of slope based method, a novel filterin...
متن کاملEstimation of the Lidar Height Offset in Coastal Vegetated Areas
Authorities operating in the field of coastal management require reliable area-wide height information for their responsibilities regarding to the safety of the coastal area. In this context the lidar technique replaces more and more traditional methods, such as terrestrial surveying, and is now the most important source for the generation of digital terrain models (DTM) in this zone. However, ...
