LANDFORM PERCEPTION ACCURACY IN SHADED RELIEF MAPS: A REPLICATION STUDY CONFIRMS THAT NNW LIGHTING IS BETTER THAN NW AGAINST THE RELIEF INVERSION EFFECT
Relief inversion effect Terrain reversal effect Shaded relief maps
2018/11/9
Relief inversion effect is a perceptual phenomenon that leads to an inverted perception of convex and concave shapes. This perceptual inversion occurs in scenes where the shading/shadows act as the ma...
AN OBJECT-BASED METHOD FOR CHINESE LANDFORM TYPES CLASSIFICATION
Landform Classification DEM Object-based Random Forest Gray-level Co-occurrence Matrix
2016/11/23
Landform classification is a necessary task for various fields of landscape and regional planning, for example for landscape evaluation, erosion studies, hazard prediction, et al. This study proposes ...
SEMI-AUTOMATIC LANDFORM MAPPING AT STEEP SLOPES
semi-automatic segmentation landform mapping image matching surface parameterization
2015/9/28
The traditional mapping on digital aerial photos and elevation models has its limits at steep slopes where the surface is only very sparsely
sampled even in high resolution data sets. As a consequenc...
Maskevarri Ráhppát in Finnmark, northern Norway – is it an earthquake-induced landform complex?
Sami rahppat coarse boulders terrain new tectonic fault and earthquake
2015/1/6
The Sami word ráhppát means rough bouldery/stony terrain with sharp-relief topography in Finnmark, northern Norway. Ráhppát is a common name in the region of the Younger Dryas landforms, yet the origi...
Landform monitoring in active volcano by UAV and SfM-MVS technique
Unmanned Aerial Vehicle (UAV) Aerial Photogrammetry Structure from Motion (SfM) Multi-view Stereo (MVS) Nishinoshima volcano Digital Elevation Model (DEM) Ortho-Mosaic Photo
2014/12/15
Nishinoshima volcano in Ogasawara Islands has erupted since November, 2013. This volcanic eruption formed and enlarged a new island, and fused the new island with the old Nishinoshima Island. We perfo...
Evolutionary geomorphology：thresholds and nonlinearity in landform response to environmental change
Evolutionary geomorphology environmental change
2009/5/15
Geomorphic systems are typically nonlinear, owing largely to their threshold-dominated nature (but due to other factors as well). Nonlinear geomorphic systems may exhibit complex behaviors not possibl...
Tectonic movements and climate changes are two main controllers on the development of landform. In order to reconstruct the history of the evolution of the landform in the Fenhe drainage b...
