Theoretical assumptions, research methodologies and results applications of innovative geological and geomorphological mapping for landslide hazard evaluation in the alpine environment are presented in the paper. Case studies from the Italian NW-Alps highlight the role of Geomatics techniques in enhancing the accuracy of multitemporal reconstructions of geomorphic processes and landforms. Aeria...

Landforms representative of sedimentary processes and environments that occurred early in martian history have been recognized in Mars Global Surveyor Mars Orbiter Camera and Mars Odyssey Thermal Emission Imaging System images. Evidence of distributary, channelized flow (in particular, flow that lasted long enough to foster meandering) and the resulting deposition of a fan-shaped apron of debri...

This thesis presents methods to enrich data modeling and analysis in the geoscience domain with a particular focus on geomorphological applications. First, a short overview of the relevant characteristics of the used remote sensing data and basics of its processing and visualization are provided. Then, two new methods for the visualization of vector-based maps on digital elevation models (DEMs)...

Relief shading is the most common type of cartographic relief representation for print and digital maps. Manual relief shading results in informative and visually pleasing representations of terrain, but it is time consuming and expensive to produce. Current analytical relief shading can be created quickly, but the resulting maps are not as aesthetically appealing and do not show landscape feat...

The authors begin the paper with the question `Do mountains exist?' They show that providing an answer to this question is surprisingly difficult and that the answer that one gives depends on the context in which the question is posed. Mountains clearly exist as real correlates of everyday human thought and action, and they form the archetype for geographic objects. Yet individual mountains lac...

Spatial discontinuity often causes poor accuracy when a single model is used for the surface modeling of soil properties in complex geomorphic areas. Here we present a method for adaptive surface modeling of combined secondary variables to improve prediction accuracy during the interpolation of soil properties (ASM-SP). Using various secondary variables and multiple base interpolation models, A...

Express. These orbiters are surveying the entire Martian surface to understand the planet’s past and the geological, climatic, and other processes responsible for its present state. They gather ever-increasing amounts of spatially extended data. Science data archived from all planetary missions prior to the 2001 Mars Odyssey mission totals approximately 5 terabytes. NASA expects that number to ...

In the last decade, interest to jointly analyze landscapes and landforms of emerged submerged areas has been expanding [...]

human intervention in intensification of natural hazards is a concern for researchers. recognizing the response of morphological phenomena to human activities is not traceable in all phenomena. small landforms could capture short-term changes caused by human interventions and react to them. playa are among the areas in which micro-landforms changes can be traced monthly or permanently. playa ar...

In Geomorphology the landforms delineation and delimitation are based on traditional techniques which is usually achieved by two different approaches: semantic and geometric. The semantic approach involves interpreting aerial photographs as well as using field knowledge to map the possible landforms extent. The geometric approach involves inferring the probability of extension on related proper...
