RECOGNITION OF DRAINAGE TUNNELS DURING GLACIER LAKE OUTBURST EVENTS FROM TERRESTRIAL IMAGE SEQUENCES
Time-lapse image sequences glacier lake outburst floods feature tracking glacier movement
2016/11/30
In recent years, many glaciers all over the world have been distinctly retreating and thinning. One of the consequences of this is the increase of so called glacier lake outburst flood events (GLOFs)....
SPATIOTEMPORAL EVALUATION OF NOCTURNAL COLD AIR DRAINAGE OVER A SIMPLE SLOPE USING THERMAL INFRARED IMAGERY
Infrared camera Cold air drainage velocity Cooling rates Cold air pooling Microclimate Radiation frost
2016/11/30
Measurements of climatic processes such as cold air drainage flows are problematic over mountainous areas. Observation of cold air drainage is not available in the existing observation network and it ...

2015/12/28
This paper concerns Sarantaporos River in Northern Greece and particularly to the part that its course is near and parallel to the national road that connects Eastern with Western Greece. We used aeri...
Dehydration and oxidation of pyrite mud and potential acid mine drainage using hyperspectral dais 7915 data (aznalcóllar, spain)
hyperspectral mine waste contamination.
2015/8/20
The observation of mine waste contamination from abandoned mines has increased during the last ten years using hyperspectral
airborne data. Acid mine drainage is the natural result by water leaching ...
A Generalization of Contour Line Based on the Extraction and Analysis of Drainage System
Map generalization Delaunay triangulation Drainage system
2015/7/10
Unlike the simplification of independent line features, the generalization of terrain contour is to handle the “line group”, which
describes the geomorphologic characteristics, such as the terrain va...

Constructing a Comprehensive Tool for Deriving Drainage Network using Semi-Open Source Tools and Comparision on Different DEM Data Sources
Drainage network DEM Hydrology tools Python ArcPy
2014/12/16
Digital elevation model (DEM) provides elevation information in raster format for an area which help in analysis as these phenomena are gravity depended. Hydrological study requires creation of draina...
QUALITY ASSESSMENT IN RIVER NETWORK GENERALISATION BY PRESERVING THE DRAINAGE PATTERN
river network generalisation quality assessment drainage pattern fuzzy logic
2014/4/24
The drainage pattern of a river network is the arrangement in which a stream erodes the channels of its network of tributaries. It can
reflect the geographical characteristics of a river network to ...
A STUDY OF VARIABLES CHARACTERIZING DRAINAGE PATTERNS IN RIVER NETWORKS
River Network Drainage Pattern Terrain Analysis GIS
2014/4/25
In GIS and in terrain analysis, drainage systems are important components. Due to local topography and subsurface geology, a drainage system achieves a particular drainage pattern based on the form an...
