Strength-weighted flow cluster method considering spatiotemporal contiguity to reveal interregional association patterns GISci. Remote Sens. (IF 6.7) Pub Date : 2023-09-05 Haiping Zhang, Xingxing Zhou, Xinyue Ye, Guoan Tang, Haoran Wang, Shangjing Jiang
ABSTRACT One of the most crucial topics in spatial interaction studies is mining patterns from extensive origin-destination (OD) flow data to capture interregional associations. However, prevailing methodologies tend to disregard the importance of using the relative closeness of interregional connections as weights, treat spatial and temporal dimensions independently, or overlook the temporal dimension

Using the transportation problem to build a congestion/threshold constrained spatial accessibility model J. Transp. Geogr. (IF 5.899) Pub Date : 2023-09-04 Jie Lin, Gordon Cromley
As the COVID-19 pandemic has shown, congestion is an important component in access to medical care. This study expands congestion-based accessibility research by imposing upper limits on demand levels and introducing minimum demand thresholds at individual facilities using the bounded transportation problem to develop different variants of congestion/threshold constrained accessibility metrics. The

Spatiotemporal variation in bamboo Solar-induced chlorophyll fluorescence (SIF) in China based on the global Orbiting Carbon Observatory-2 (OCO-2) carbon satellite and study on the response to climate and terrain GISci. Remote Sens. (IF 6.7) Pub Date : 2023-09-05 Yanxin Xu, Xuejian Li, Huaqiang Du, Fangjie Mao, Guomo Zhou, Zihao Huang, Di’en Zhu, Qi Chen, Chi Ni, Keruo Guo
ABSTRACT Bamboo forests have a high carbon sequestration potential. Solar-induced chlorophyll fluorescence (SIF) provides fresh insights into the temporal and geographical variations in bamboo development and its interactions with the environment. SIF can serve as a probe for photosynthesis. In this study, we used distribution information on Chinese bamboo forests as well as a global SIF product, the
