A multilevel dataset of landform mapping and geomorphologic descriptors for the Loess Plateau of China [PDF]

Scientific Data
The Loess Plateau is a region of importance in geomorphologic research because of its typical loess layers and intense surface erosion. Analysing the landforms on the Loess Plateau is helpful for understanding changes in the surface environment. However,

Large Scale Landform Mapping Using Lidar DEM

ISPRS International Journal of Geo-Information, 2015
In this study, LIDAR DEM data was used to obtain a primary landform map in accordance with a well-known methodology. This primary landform map was generalized using the Focal Statistics tool (Majority), considering the minimum area condition in ...

Geomorphometry-Automatic Landform Classification

, 2018
In the past, landforms were represented in physiographic and morphometric maps by hand drawing. With developments in digital elevation models (DEM), geographic information systems (GIS) and image analyses, automatic extraction of landforms from morphological parameters and data storage in databases is now possible and are actively utilized in various ...

Enhancing performance of multi-temporal tropical river landform classification through downscaling approaches [PDF]

, 2022
Multi-temporal remote sensing imagery has the potential to classify river landforms to reconstruct the evolutionary trajectory of river morphologies. Whilst open-access archives of high spatial resolution imagery are increasingly available from satellite

Supervised classification of landforms in Arctic mountains [PDF]

Permafrost and Periglacial Processes, 2019
AbstractErosional and sediment fluxes from Arctic mountains are lower than for temperate mountain ranges due to the influence of permafrost on geomorphic processes. As permafrost extent declines in Arctic mountains, the spatial distribution of geomorphic processes and rates will change.

SGCN: A multi-order neighborhood feature fusion landform classification method based on superpixel and graph convolutional network

International Journal of Applied Earth Observations and Geoinformation, 2023
To address key issues with traditional landform classification methods that impact the integrity and continuity of the analysis area, as well as neglecting neighboring features, We presents a novel approach called superpixel-based graph convolutional ...
