Permafrost Terrain Disturbance Susceptibility in the Nacho Nyäk Tagé (Stewart River) Watershed, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The Nacho Nyäk Tagé (Stewart River) watershed in central Yukon (Canada) is characterized by discontinuous permafrost that is locally highly sensitive to thaw. This study aims to map the spatial distribution of permafrost terrain disturbances (PTDs) in the watershed and model thaw susceptibility to support community‐led land‐use planning by the

Strumenti, tecniche e soluzioni Open Source a confronto per l’elaborazione fotogrammetrica delle immagini digitali in ambito archeologico

Archeomatica, 2019
This work wants to be an overview about the various “open source” software that can be used to obtain rendering and photogrammetric data geo-referenced from digital photos. In fact, all the phases of digital photogrammetric processing can be performed by

Geodetic surveying and creation of a map of the obstacles of the future airport Golubić - Bihać [PDF]

Tehnika
In the area of the planned airport Golubić - Bihać, a geodetic survey and creation of a map of obstacles was carried out with the aim of detailed detection of potential dangers in the airspace. Airborne laser scanning technology (LiDAR) was used for data

NUMERICAL INVESTIGATION OF THE ALPHA PARAMETRIZED DTM WITH THE CLASSICAL DTM

Journal of Science and Arts
In this paper, solutions of some differential equations are found using alpha parametrized differential transform method (α–PDTM). The results are compared with the exact solution and the results found from the classical differential transform method (DTM). The optimal values of are found for which the error at some particular domain point is minimal.

Resource reservation in DTM

First IEEE Symposium on Global Data Networking, 2002
DTM is an optical network with bandwidth reservation and support for dynamic reallocation of bandwidth. DTM is designed for real-time multimedia applications and for high-speed computer communication. DTM provides a service with real-time guarantees: it allows reservation of bandwidth, and has constant delay between two nodes.

UAVs unveil the role of small scale vegetation structure on wader nest survival

Remote Sensing in Ecology and Conservation, EarlyView.
In this study, we combine high‐resolution vegetation structural metrics derived from unmanned aerial vehicle (UAV) imagery with on‐field wader nest survival monitoring. We show that the immediate vegetation height and heterogeneity within a 2‐meter buffer surrounding the clutch of the recorded ground‐nesting wader species positively influenced its ...

The Linear Information Coupling Problems [PDF]

, 2014
Many network information theory problems face the similar difficulty of single-letterization. We argue that this is due to the lack of a geometric structure on the space of probability distribution.

Wall‐to‐wall Amazon forest height mapping with Planet NICFI, Aerial LiDAR, and a U‐Net regression model

Remote Sensing in Ecology and Conservation, EarlyView.
Tree canopy height is a key indicator of forest biomass and structure, yet accurate mapping across the Amazon remains challenging. Here, we generated a canopy height map of the Amazon forest at ~4.8 m resolution using Planet NICFI imagery and a deep learning U‐Net model trained with airborne LiDAR data.

Effect of photogrammetric RPAS flight parameters on plani-altimetric accuracy of DTM

Open Geosciences, 2020
Remotely piloted aerial systems (RPASs) are gaining fast and wide application around the world due to its relative low-cost advantage in the acquisition of high-resolution imagery.
