High-precision remote sensing mapping of aeolian sand landforms based on deep learning algorithms

Open Geosciences, 2022
It is significant to adopt deep learning algorithms and higher-resolution remote sensing images in mapping large-scale and high-precision of aeolian landform. In this study, the western part of Horqin Sandy Land was taken as the study area.

Greater sage‐grouse seasonal habitat associations: A review and considerations for interpretation and management applications

The Journal of Wildlife Management, EarlyView.
We examined habitat associations from second‐ and third‐order habitat selection studies conducted on greater sage‐grouse and summarize the types of designs used and the qualitative associations reported. We suggest a combination of study design choices and context‐dependence selection patterns can prohibit the transferability of study findings when the

Deep learning-based automated terrain classification using high-resolution DEM data

International Journal of Applied Earth Observations and Geoinformation, 2023
Landforms are a fundamental component of the natural environment, and digital terrain mapping on a large spatial scale is important when studying landforms. In this study, we adopted a semantic segmentation model in computer vision to classify elementary

An Automatic Digital Terrain Generation Technique for Terrestrial Sensing and Virtual Reality Applications [PDF]

, 2019
The identification and modeling of the terrain from point cloud data is an important component of Terrestrial Remote Sensing (TRS) applications. The main focus in terrain modeling is capturing details of complex geological features of landforms. Traditional terrain modeling approaches rely on the user to exert control over terrain features.

Impact of the Water Reservoir and River Engineering Structures on Longitudinal and Transverse (Dis)connectivity Associated With Sediment Transfer

Land Degradation &Development, EarlyView.
ABSTRACT Human impact in the form of reservoir construction and river regulation downstream of reservoirs, is causing irreversible alterations to hillslope and river channel connectivity in river catchments. This disruption in the dynamic equilibrium of the river is attributed to sediment accumulation upstream of the reservoir's dam, limited sediment ...

INDMF Based Regularity Calculation Method and Its Application in the Recognition of Typical Loess Landforms

Remote Sensing, 2022
The topographical morphology of the loess landform on the Loess Plateau exhibits remarkable textural features at different spatial scales. However, existing topographic texture analysis studies on the Loess Plateau are usually dominated by statistical ...

Exploring Basement Surface relationship of north-west Bengal Basin using satellite images and tectonic modeling [PDF]

arXiv, 2020
The Bengal basin is one of the thickest sedimentary basins and is being constantly affected by the collision of the Indian plate with the Burma and Tibetan plates. The northwest part of the basin, our study area, is one of the least explored areas where the shallowest faulted basement is present. Controversies exist about the origin of the basement and

Decadal Variability of Differential Frost Heave on Incipient Sorted Patterned Ground in the Southern Japanese Alps

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Differential frost heave between fine (earthy) and coarse (gravelly) domains was monitored over 10 years (2013–2023) on a mountain‐top flat ground subjected to both frequent diurnal and deep seasonal freezing. Monitoring objects include, ground heave, soil temperature down to 55 cm, soil moisture, air temperature, rainfall, and snow depth. The

Differences in triggering conditions between embedded and isolated convection initiation during a Meiyu season in China

Quarterly Journal of the Royal Meteorological Society, EarlyView.
During the summer monsoon, a long‐lasting stratiform rainfall system (SRS) hovers over China's Yangtze–Huai River Basin (YHRB), generating two distinct convective environments that are either influenced by or independent of the SRS. Correspondingly, both embedded and isolated convection initiation (CI) occur with different spatiotemporal ...
