2010/2/5
Here, we present a mapping method OBLIMAP, which projects and interpolates fields like surface temperature, surface mass balance, and surface height between a geographical based coordinate system of a...
Rockfall hazard mapping along a mountainous road in Switzerland using a GIS-based parameter rating approach
Rockfall hazard mapping a mountainous road Switzerland a GIS-based parameter rating approach
2009/12/10
A posteriori studies of rock slope instabilities generally show that rockfalls do not occur at random locations: the failure zone can be classified as sensitive from geomorphological evidence. Zones s...
Impact of mapping errors on the reliability of landslide hazard maps
mapping errors landslide hazard maps
2009/12/9
Identification and mapping of landslide deposits are an intrinsically difficult and subjective operation that requires a great effort to minimise the inherent uncertainty. For the Staffora Basin, whic...
A new method for avalanche hazard mapping using a combination of statistical and deterministic models
avalanche hazard mapping statistical and deterministic models
2009/12/9
The purpose of the present paper is to propose a new method for avalanche hazard mapping using a combination of statistical and deterministic modelling tools. The methodology is based on frequency-wei...
