strevisani/MADSurfaceTexture: V1.1 plus R package
, 2023 Geostatistical-based tools for surface roughness or image texture analysis based on the robust estimator MAD and on differences of order 2. These prototypes aim to promote the use and further development of these approaches in geomorphometry and remote ...

Locally adjusted curve approximation smoothing of contour polylines
Journal of Spatial Information ScienceNumerically interpolated contour lines (NICL) developed from a high-resolution, accurate digital elevation model (DEM) can be considered the most accurate contour baseline available from surveyed data.

Geomorphometry: Today and Tomorrow [PDF]
, 2018 This paper summarizes the current state-of-the-art in geomorphometry and describes the innovations that are close at hand and will be required to push digital terrain modeling forward in the future. These innovations will draw on concepts and methods from computer science and the spatial sciences and require greater collaboration to produce “actionable”

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 4, April 2025.Abstract Arctic shrub productivity trends display variability at multiple spatial scales. Fine‐scale studies have generally observed the greatest shrub expansion in landscape positions that accumulate water and nutrients. While considerable work has focused on the mediating effect of these resources on growth responses to warming, less is known about ...

Wood jam mobility in a morphologically active river in northern Chilean Patagonia
Earth Surface Processes and Landforms, Volume 50, Issue 3, 15 March 2025.This study examined post‐eruption wood jam mobility and channel changes in the Blanco River. Floodplain collapses led to large sediment yields. High wood jam mobility rates were reported. Larger, less compact wood jams persist in stable areas; new and missing jams are smaller and linked to deposition and erosion, respectively.

Image-based surface reconstruction in geomorphometry - merits, limits and developments
, 2016 . Photogrammetry and geosciences have been closely linked since the late 19th century due to the acquisition of high-quality 3-D data sets of the environment, but it has so far been restricted to a limited range of remote sensing specialists because of ...
