Fine-Grained Climate Classification for the Qaidam Basin

open access: yesAtmosphere, 2022
The Qaidam Basin is a sensitive climate transition zone revealing a wide spectrum of local climates and their variability. In order to obtain an objective and quantitative expression of local climate regions as well as avoid the challenge to pre-define ...

Building Damage Detection Based on OPCE Matching Algorithm Using a Single Post-Event PolSAR Data

open access: yesRemote Sensing, 2021
Synthetic aperture radar (SAR) is an effective tool in detecting building damage. At present, more and more studies detect building damage using a single post-event fully polarimetric SAR (PolSAR) image, because it permits faster and more convenient ...

Evaluation of Land Surface Temperature Retrieval from Landsat 8/TIRS Images before and after Stray Light Correction Using the SURFRAD Dataset

open access: yesRemote Sensing, 2020
Landsat 8/thermal infrared sensor (TIRS) is suffering from the problem of stray light that makes an inaccurate radiance for two thermal infrared (TIR) bands and the latest correction was conducted in 2017. This paper focused on evaluation of land surface

Geographic information systems [PDF]

open access: yesWIREs Computational Statistics, 2009
AbstractThis article presents an overview of the development, capabilities, and utilization of geographic information systems (GISs). There are nearly an unlimited number of applications that are relevant to GIS because virtually all human interactions, natural and man‐made features, resources, and populations have a geographic component.

A New FAPAR Analytical Model Based on the Law of Energy Conservation: A Case Study in China

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2014
The fraction of absorbed photosynthetically active radiation (FAPAR) characterizes the energy-absorption ability of the vegetation canopy. It is a critical input to many land-surface models such as crop growth models, net primary productivity models, and
