Zhou, J. (author), Menenti, M. (author), Jia, Li (author), Gao, Bo (author), Zhao, Feng (author), Cui, Yilin (author), Xiong, Xuqian (author), Liu, Xuan (author), Li, Dengchao (author)Spatiotemporal residual noise in terrestrial earth observation products, often caused by unfavorable atmospheric conditions, impedes their broad applications. Most users prefer to use gap-filled remote sensing products with time series reconstruction (TSR) algorithms. Applying currently available implementations of TSR to large-volume...journal article 2023

Zhou, J. (author), Liu, Xuan (author), Xiong, Xuqian (author), Jia, Li (author), Lu, Jing (author), Cui, Yilin (author)Satellite-based Earth Observation systems archived a variety of vegetation products during the last 50 years, which can reveal regional to global ecosystem dynamics across diverse spatiotemporal scales. The anomaly metrics such as Vegetation Condition Index (VCI) defined by comparing the current vegetation growth condition to historical...conference paper 2022

Xiong, Q. (author), Zhu, Q. (author), Zlatanova, S. (author), Huang, L. (author), Zhou, Y. (author), Du, Z. (author)Aiming at the increasing requirements of seamless indoor and outdoor navigation and location service, a Chinese standard of Multidimensional Indoor Location Information Model is being developed, which defines ontology of indoor location. The model is complementary to 3D concepts like CityGML and IndoorGML. The goal of the model is to provide an...conference paper 2013
