Traditional methods of terrestrial survey to acquire DEM cannot meet the requirement of acquiring large quantities of data in real time, but the DSM can be quickly obtained by using the dual antenna s...
Invasive plant species represent a serious threat to biodiversity and landscape as well as human health and socio-economy. To successfully fight plant invasions, new methods enabling fast and efficien...
Multispectral Airborne Laser Scanning provides a new opportunity for airborne data collection. It provides high-density topographic surveying and is also a useful tool for land cover mapping. Use of a...
During the last 20 years, airborne laser scanning (ALS), often combined with multispectral information from aerial images, has shown its high feasibility for automated mapping processes. Recently, the...
As the linear array sensor such as multispectral and hyperspectral sensor has great potential in disaster monitoring and geological survey, the quality of the image geometric rectification should be g...
Airborne pushbroom systems for the direct acquisition of digital imagery enable the simultaneous capture of high quality 3D and multispectral information of a scene. The combination of geometric and r...
Glaciers are interesting phenomena to scientists, mountaineers and tourists. Glaciers have a great impact on the local economy, power generation and water supply. Furthermore, the behaviour of glacier...
As glaciers are good indicators for the regional climate, most of them presently undergo dramatic changes due to climate change. Remote sensing techniques have been widely used to identify glacier sur...
Canopy height distributions were created from small-footprint airborne laser scanner data for mature coniferous forest in two forest areas in Norway. In total, 82 and 70 georeferenced field sample plo...
The applicability of Visible, Near-Infrared and Short Wave Infrared (VNIR/SWIR) hyperspectral imagery for soil property mapping decreases when surfaces are partially covered by vegetation. The objecti...
In our study we classified grassland vegetation types of an alkali landscape (Eastern Hungary), using different image classification methods for hyperspectral data. Our aim was to test the applicabili...
airborne digital imagers: an overview & analysis.
A comprehensive Geographic Information System (GIS) was developed to determine how the laser intensity of an Airborne Laser Scanning (ALS) system was affected by 1) geometry and 2) surface type. The...
This paper describes direct interactive relative orientation method between terrestrial digital images and laser scanner data. Traditionally, the orientation between images and 3D data requires inte...
Derivation of Roof Types by Cluster Analysis in Parameter Spaces of Airborne Laser Scanner Point Clouds.
