Tree Crown Delineation from High Resolution Airborne Lidar Based on Densities of High Points
Tree detection and tree crown delineation from Airborne LiDAR has been focusing mostly on utilizing the canopy height model (CHM). This paper presents a method for individual tree crown delineation based on densities of high points (DHP) from the high resolution Airborne LiDAR. The DHP method relies on the fact that the density of received laser pulses above a certain height is high at the cent...
متن کاملMatching of High Resolution Satellite Image and Tree Crown Map
In forest area, there are few landmarks to be ground control points (GCPs) used for registration of satellite images or maps. Additionally, geographic information from the Global Positioning System (GPS) in field measurement survey is insufficient accuracy to identify individual tree crowns from satellite image. In this study, we propose the method of identifying individual tree crowns from sat...
متن کاملTree Crown Delineation from Digital Elevation Models and High Resolution Imagery
The aim of this study was to develop a methodology to delineate accurately tree crowns using digital elevation models independently of source (laser scanned data or stereoscopic pairs) and to identify the complementary information that can be obtained from high resolution imagery. This methodology uses the Watershed algorithm as the baseline. However the direct application of this algorithm gen...
متن کاملSuper-resolution Mapping for Extraction of Urban Tree Crown Objects from Vhr Satellite Images
Extraction of individual tree crown objects in urban areas using available VHR space-borne imaging systems remains a challenging image processing task mainly because of two factors: the limited spectral information offered by the sensors and their limited spatial resolution. The spectral information of available VHR satellite sensors is not sufficient to discriminate tree crowns from other land...
متن کاملObject-Oriented Method for Automatic Extraction of Road from High Resolution Satellite Images
As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...
