High‐resolution snow depth prediction using Random Forest algorithm with topographic parameters: A case study in the Greiner watershed, Nunavut [PDF]

, 2022
Increased surface temperatures (0.7℃ per decade) in the Arctic affects polar ecosystems by reducing the extent and duration of annual snow cover. Monitoring of these important ecosystems needs detailed information on snow cover properties at resolutions (

Geomorphometric analysis of landform pattern using topographic position and ASTER GDEM [PDF]

, 2017
A number of research have been carried out on geomorphology using a conventional approach to classify the landform; this has a tendency of producing misleading result, due to ruggedness and inaccessibility of the terrain.

Building Damage Characterization for the 2016 Amatrice Earthquake Using Ascending–Descending COSMO-SkyMed Data and Topographic Position Index

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2018
The August 24, 2016, M 6.2 Amatrice earthquake in central Italy was one of the most destructive earthquakes in recent years, and it caused considerable human losses. The goal of this study is to distinguish between collapsed and standing buildings in the town of Amatrice using synthetic aperture radar (SAR) data acquired from the COSMO-SkyMed satellite.

Comparative Study of Landform Mapping Using Terrain Attributes and Topographic Position Index (TPI): a Case Study in Al-Alamien – Ras El-Hekma Region, Egypt [PDF]

Alexandria Science Exchange Journal, 2018
The aim of this study is to compare the classification of the landscape of the area located between Al-Alamien and Ras El-Hekma to landform classes using two different classification methods; the terrain attributes method and the topographic position index (TPI) method. Terrain attributes classification method derived from a digital elevation model and
