Comparison of Digital Elevation Data from Airborne Laser and Interferometric Sar Systems
Requirements for precise digital elevation data (i.e., Digital Elevation Models, or DEMs) of varying levels of detail are being formulated for different fields of application. The degree of detail found in a DEM is usually characterized by the horizontal sample spacing and by the vertical accuracy of the samples. Increased detail is normally associated with increased cost to the user, which fue...
متن کاملComparison of Grid-Based and Segment-Based Estimation of Forest Attributes Using Airborne Laser Scanning and Digital Aerial Imagery
Forest management planning in Finland is currently adopting a new-generation forest inventory method, which is based on interpretation of airborne laser scanning data and digital aerial images. The inventory method is based on a systematic grid, where the grid elements serve as inventory units, for which the laser and aerial image data are extracted and the forest variables estimated. As an alt...
متن کاملComparison of a grid-based and segment-based estimation of forest attributes using airborne laser scanning and digital aerial imagery
In Finland, the forest inventory for the forest management planning has traditionally been based on visual inventory by stands. In this method, the forest stands that are delineated on aerial photographs on the basis of their growing stock and site-related characteristics are measured or estimated in the field. The method is considered too labour-intensive, and it requires a large amount of fie...
متن کاملGeneration of 3d City Models from Airborne Laser Scanning Data
Airborne laser scanners enable the geometric acquisition of the terrain surface, including objects like trees or buildings which rise from the terrain. Even though for a number of applications a so{called Digital Surface Model (DSM) representing the surface geometry by an object independent distribution of points is su cient, the further quali cation of the original scanner data is necessary fo...
متن کاملLand Cover Dependent Derivation of Digital Surface Models from Airborne Laser Scanning Data
In contrast to the algorithms for determining digital terrain models (DTMs) from airborne laser scanning (ALS) data, those for the generation of digital surface models (DSMs) are rather straightforward. A common way to derive DSMs is the determination of the highest point within a defined raster cell (DSMmax) or the determination of the DSM heights based on moving least squares interpolation e....
