During the last two decades surface elevation data have been gathered over the Greenland Ice Sheet (GrIS) from a variety of different sensors including spaceborne and airborne laser altimetry, such as...
During the past few decades the Greenland and Antarctic ice sheets have lost ice at accelerating rates, caused by increasing surface temperature. The melting of the two big ice sheets has a big impact...
We have used a set of Ground Control Points (GCPs) derived from altimetry measurements from the Ice, Cloud and land Elevation Satellite (ICESat) to evaluate the quality of the 30 m posting ASTER (Adva...
Since 2003 the spaceborne laser altimetry system on board of NASAs Ice, Cloud and land Elevation Satellite (ICESat) has acquired a large world-wide database of full waveform data organized in 15 prod...
Laser altimetry seems to be an attractive method for the fast acquisition of up to date height data which can be useful for various river management tasks. The Geo-information and ICT department of th...
The new Dutch national digital elevation model (AHN), acquired with laser altimetry, is almost complete. Local water boards want to use the laser data for water management tasks such as determining ...
Offsets between overlapping strips of laser altimetry data serve as the input for strip adjustment procedures that estimate and eliminate systematic errors in laser altimetry datasets. For a three-di...
Perceptual organization is to group sensory primitives arising from a common underlying cause by imposing structural organization on sensory data. It has been emphasized as a robust intermediate-level...
The need fo r accurate geometric and radiometric info rmation over la rge a reas has b ecome increasingly imp o rtant. Laser altimetry is one of the key technologies fo r obtaining this geometric info...
Detailed topographic data collected with an airborne laser scanner can help determine the extent of bank erosion and identify banks that are more vulnerable to bank collapse and thus require stabiliza...
A point set obtained by laser altimetry represents points from not only the ground surface but also objects found on it. For civil works applications points representing the surface of non-ground obje...
Laser altimetry has, and is continuing to have a profound impact on photogrammetry. This paper discusses the interrelationship between the two fields, identifies problems, and suggests a common resear...
Preliminary results of a study to estimate the instrument base required to support a competitive laser altimetry sector within the global remote sensing industry are presented. The recent growth of th...
Two new laser altimeter satellites are being launched by NASA in the near future: the ICESat (Ice, Clouds, Elevation) satellite and the VCL (Vegetation Canopy Lidar) satellite. Although each satellite...
Airborne laser altimetry is a highly efficient and accurate method of obtaining data for the determination of visible surface topography. With minimal processing, the laser data can provide coordinate...
