A comparison of supraglacial lake observations derived from MODIS imagery at the western margin of the Greenland ice sheet
Supraglacial lakes (SGLs) affect the dynamics of the Greenland ice sheet by storing runoff and draining episodically. We investigate the evolution of SGLs as reported in three datasets, each based on automated classification of satellite imagery. Although the datasets span the period 2001–10, there are differences in temporal sampling, and only the years 2005–07 are common. By subsampling the m...
متن کاملAccuracy Analysis of Dems Derived from Aster Imagery
ASTER acquires along track stereoscopic imagery, with a spatial resolution of 15 meters. Automatic generation of Digital Elevation Models (DEMs) from these images is a well established process, implemented in many commercial software packages. It can provide relief information for areas with poor coverage of topographic mapping. This paper presents a study of the accuracy achieved in DEMs extra...
متن کاملGlacier Monitoring from Aster Imagery: Accuracy and Applications
The optical sensor ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) on board the Terra satellite offers new possibilities for worldwide glacier monitoring. In this paper, its capability and accuracy for selected glaciological applications is evaluated. (a) ASTER’s along-track stereo sensor allows for photogrammetric DEM generation. Here, we apply PCI Geomatica Orthoengine ...
متن کاملModeling of subglacial hydrological development following rapid supraglacial lake drainage
The rapid drainage of supraglacial lakes injects substantial volumes of water to the bed of the Greenland ice sheet over short timescales. The effect of these water pulses on the development of basal hydrological systems is largely unknown. To address this, we develop a lake drainage model incorporating both (1) a subglacial radial flux element driven by elastic hydraulic jacking and (2) downst...
متن کاملCreating Digitial Elevation Models and Orthoimages from ASTER Imagery
The aim of this tutorial is to show how to easily create a Digital Elevation Model (DEM) and orthorectified image from free ASTER satellite imagery. PCI Geomatica OrthoEngine is the software package used to perform the processing. The imagery used in this tutorial is from Southern Scotland, around Loch Doon in the United Kingdom. These web sites provide contextual pictures of the area….
