Forest Modeling using Airborne Lidar
Building up forest inventories for performing forest management is currently done manually through field cruises and interpretation of the aerial imagery, which is a labor-intensive task. Airborne lidar technology is capable of building a point cloud off the top surface of the ground objects. Modeling urban areas from the lidar has been successfully accomplished. However, for forest modeling, t...
متن کاملForest Delineation Based on Airborne LIDAR Data
The delineation of forested areas is a critical task, because the resulting maps are a fundamental input for a broad field of applications and users. Different national and international forest definitions are available for manual or automatic delineation, but unfortunately most definitions lack precise geometrical descriptions for the different criteria. A mandatory criterion in forest definit...
متن کاملA Novel Algorithm for Road Extraction from Airborne Lidar Data
Road data in 3-dimensional forms is required for a variety of geospatial applications e.g. road maintenance, transport planning and location-based services. Although airborne lidar can produce dense point clouds from which 3-dimensional road information can be retrieved in detail, lidar data is often incomplete due to the line-of-sight requirement, and therefore a better result of information e...
متن کاملExtraction of Non-forest Trees for Biomass Assessment Based on Airborne and Terrestrial LiDAR Data
The main goal of the federal funded project ‘LiDAR based biomass assessment’ is the nationwide investigation of the biomass potential coming from wood cuttings of non-forest trees. In this context, first and last pulse airborne laserscanning (F+L) data serve as preferred database. First of all, mandatory field calibrations are performed for pre-defined grove types. For this purpose, selected re...
متن کاملImproving estimates of roughness length in a road weather prediction model using airborne LIDAR data
Changes in the aerodynamic characteristics of a site can have a major influence on the wind regime at the surface/air interface along a road which in turn has a local effect on road surface temperatures. Traditionally a parameter known as roughness length (Z0) is used as the primary measure of the aerodynamic roughness of a surface, but Z0 is notoriously difficult to estimate. This study takes ...
