NON-RIGID MULTI-BODY TRACKING IN RGBD STREAMS

We have proposed a novel framework to generate the firstly publicly released 10-m global PCGs map in 2020 derived from Sentinel-2. Results show that the global PCGs area is approximately 14,259.85 km² in 2020, mainly distributed between 30° N and 40° N. China, not only has the largest area of PCGs in Asia but also ranks first worldwide, with a PCGs area of 8,224.90 km², making up 57.67 % of the global and 83.29 % of the Asia. The overall accuracy of our Global-PCG-10 is satisfactory of 92.08 %.

In this manuscript, we developed a 500-m spatial resolution monthly SIF dataset for the China region (CNSIF) from 2003 to 2022 based on high-resolution apparent reflectance and thermal infrared data. The comparison of CNSIF with tower-based SIF observations, tower-based GPP observations, MODIS GPP products, and other SIF datasets has validated CNSIF's ability to capture photosynthetic activity across different vegetation types and its potential for estimating carbon fluxes.

In this paper we generated the first national maize phenology product with a fine spatial resolution (30 m) and a long temporal span (1985–2020) in China, using Landsat images. The derived phenological indicators agree with in situ observations and provide more spatial details than moderate resolution phenology products. The extracted maize phenology dataset can support precise yield estimation and deepen our understanding of the response of agroecosystem to global warming in the future.
