Mapping surveys based on terrestrial laser scanning (TLS) are common nowadays for different purposes such as documentation of cultural heritage assets. The chance to extract relevant information from ...
Laser Scanning 2017 is the latest of a series of ten ISPRS workshops covering various aspects of space-borne, airborne, mobile and terrestrial laser scanning in both indoor and outdoor environments. T...
Since the mid-1990s, the Institute of Photogrammetry and Remote Sensing (I.P.F.) is engaged in Airborne Laser Scanning (ALS) in research and development. Scientific contributions have been made...
During the last decade various techniques have been proposed to extract the ground surface from airborne LIDAR data. The basic problem is the separation of terrain points from off-terrain points whi...
Terrestrial laser scanning has been rapidly adopted around the world as a tool for capturing three-dimensional survey data in a variety of applications. This rapid take up continues, but clients, and...
High-resolution digital terrain models (DTM) provide accurate descriptions of our surrounding with respect to its 2.5D shape. Besides that existing cartographic databases provide detailed 2D represe...
We evaluate the potential of deriving a vegetation leaf area index (LAI) from small footprint airborne laser scanning data. Based on findings from large area histograms of discrete laser return...
It is well known that characteristics of individual trees, such as tree height, biomass and crown area, can be derived from airborne laser scanning (ALS) and that heights for individual trees can be ...
The determination of hydrodynamic vegetation density of floodplain forests in the Netherlands is currently based on manually delineated vegetation types and a lookup table to convert these into vege...
Countrywide collection of laser scanning, mainly due to DTM derivation, is becoming increasingly attractive. Since Finland is a large country, optimization of scanning parameters is important from th...
The Taita Hills, located in south-eastern Kenya, is one of the world’s biodiversity hotspots. Despite the recognized ecological importance of this region, the landscape has been heavily fragmented d...
New technologies often turn heads the first time they appear. Laser scanning is one such new technique, which has impressed many users by the ability of point clouds to provide an understanding of c...
Airborne laser scanning (ALS) requires GNSS (Global Navigation Satellite System; e.g. GPS) and an IMU (Inertial Measurement Unit) for determining the dynamically changing orientation of the scanning ...
Recently it was accomplished in Brazil one of the first surveying for application in projects of implantation of highways using that new technology. This survey was made in a corridor with approxi...
Urban environments of modern cities are described digitally in large public databases and datasets of e.g. laser scanning and ortho photos. These data sets are not necessarily linked to each other, ...
