Semantic-centric change detection framework: considering spatiotemporal heterogeneity and spatiotemporal correlation of land cover

open access: yesInternational Journal of Digital Earth
The semantic change detection (SCD) task aims to detect ‘from-to’ change types of land cover occurring over time in registered bitemporal remote sensing images.

Changes in Spring Phenology in the Three-Rivers Headwater Region from 1999 to 2013

open access: yesRemote Sensing, 2014
Vegetation phenology is considered a sensitive indicator of terrestrial ecosystem response to global climate change. We used a satellite-derived normalized difference vegetation index to investigate the spatiotemporal changes in the green-up date over ...

Hand, foot and mouth disease: spatiotemporal transmission and climate [PDF]

open access: yes, 2011
BACKGROUND: The Hand-Foot-Mouth Disease (HFMD) is the most common infectious disease in China, its total incidence being around 500,000~1,000,000 cases per year. The composite space-time disease variation is the result of underlining attribute mechanisms

Ozone Sensitivity Analysis and Ozone Formation Regimes Division in the Beijing–Tianjin–Hebei Region Based on Satellite Remote Sensing Data

open access: yesAtmosphere, 2023
In recent years, the concentration of surface ozone (O3) has increased in China. The formation regime of ozone is closely related to the ratio of volatile organic compounds (VOCs) to nitrogen oxides (NOx). To explain this increase in ozone, we determined
