Characterising the ocean frontier : a review of marine geomorphometry [PDF]
, 2016 Geomorphometry, the science that quantitatively describes terrains, has traditionally focused on the investigation of terrestrial landscapes. However, the dramatic increase in the availability of digital bathymetric data and the increasing ease by ...

On the uncertainty of stream networks derived from elevation data: the error propagation approach [PDF]
, 2010 DEM error propagation methodology is extended to the derivation of vector-based objects (stream networks) using geostatistical simulations. First, point sampled elevations are used to fit a variogram model.

Uncertainties Related to Scale and Sampling Window Size in Defining Macro Landforms
Coğrafya Dergisi, 2023 This study focuses on the statistical significance of sampling window sizes, which are used to define macro landforms and the differences they cause in definitions.

Towards the optimal Pixel size of dem for automatic mapping of landslide areas [PDF]
, 2017 Determining appropriate spatial resolution of digital elevation model (DEM) is a key step for effective landslide analysis based on remote sensing data. Several studies demonstrated that choosing the finest DEM resolution is not always the best solution.

Spectral filtering as a method of visualising and removing striped artefacts in digital elevation data [PDF]
, 2008 Spectral filtering was compared with traditional mean spatial filters to assess their ability to identify and remove striped artefacts in digital elevation data. The techniques were applied to two datasets: a 100 m contour derived digital elevation model

GIS-based analysis of doline density on Miljevci karst plateau (Croatia)
Acta Carsologica, 2022 The doline density and their spatial distribution analysis is one of the methods used for karst relief morphostructural analysis. We present the results of morphometric features, doline spatial distribution and their relationship on Miljevci karst ...
