The ability to develop spatially distributed models of topographic change is presenting new
capabilities in geomorphic research. High resolution maps of elevation change indicate …

Quantitative characterization of the size and shape of volcanic edifices is an essential step
towards the understanding of factors controlling volcano growth and morphology. The recent …

Civil engineering uses digital elevation models (DEMs) and orthophotos as basic material to
be able to design and execute any project. UAV photogrammetry has made it possible to …

This paper presents recommended methodologies for the quantitative analysis of landslide
hazard, vulnerability and risk at different spatial scales (site-specific, local, regional and …

The availability of high-resolution Digital Surface Models of coastal environments is of
increasing interest for scientists involved in the study of the coastal system processes …

Starting from a concept of the land surface, its definition and subdivision from Digital
Elevation Models (DEMs) is considered. High-resolution DEMs from active remote sensing …

Agricultural watersheds tend to be places of intensive farming activities that permanently
modify their microtopography. The surface characteristics of the soil vary depending on the …

This article examines how the methods and data sources used to generate DEMs and
calculate land surface parameters have changed over the past 25years. The primary goal is …

An evolving, living organic/inorganic covering, soil is in dynamic equilibrium with the
atmosphere above, the biosphere within, and the geology below. It acts as an anchor for …

Erosion and deposition modelling should rely on field data. Currently these data are seldom
available at large spatial scales and/or at high spatial resolution. In addition, conventional …
