1 paź 2022 · 1. Introduction. Terrain is considered one of the most important natural geographic features and is a key factor in physical processes.
17 sie 2018 · These researches of the landform classification used digital elevation models (DEMs) and new algorithms, such as the artificial neural network (ANN) and self-organizing maps (SOM). This paper is aimed at providing a review of landform characteristics and classifications in different scale.
5 mar 2024 · To detect the rock wall/rock slope, the slope, standard deviation and multi-scale TPI variables are important, high values of which increase the probability of classifying this landform.
1 kwi 2020 · The proposed approach involves these following four steps: (1) data preparation, (2) DL network building and training, (3) accuracy test and validation, and (4) landform analysis of study area. First, remote sensing imagery, DEMs, and their derivatives were collected as the input dataset.
30 cze 2022 · Based on its unique geo-meanings, Li et al proposed a method based on the boundary profile to conduct pix-based landform classification, which fully confirms its great potential in quantitatively analyzing landforms at a macro level (Li et al. Citation 2017).
1 wrz 2018 · This method categorizes the landscape into two levels. The first one is slope position, and identifies (i) hilltops – which are higher than their surroundings and (ii) valley bottoms – which are lower than the surrounding neighbourhood. Values close to zero represent either a flat or a mid-slope area distinguished by a threshold of ±5°.
