Mapping the vegetation distribution and dynamics of a wetland using adaptive-stacking and Google Earth Engine based on multi-source remote sensing data

Xiangren Long, Xinyu Li, Hui Lin, Meng Zhang
2021 International Journal of Applied Earth Observation and Geoinformation  
In this paper, an adaptive-stacking algorithm based on Google Earth Engine was proposed to map the vegetation distribution of Dongting Lake wetland using Sentinel-1/2 and DEM data.  ...  Subsequently, LandTrendr was utilized to analyze vegetation dynamics over the 1999-2018 based on Landsat normalized combustion ratio time-series.  ...  However, classification result using adaptive-stacking and sentinel-1/2 proposed in this paper has a higher spatial resolution (10 m) and accuracy (94.59%).  ...

Evaluating Effects of Medium-Resolution Optical Data Availability on Phenology-Based Rice Mapping in China

Ruoqi Liu, Geli Zhang, Jinwei Dong, Yan Zhou, Nanshan You, Yingli He, Xiangming Xiao
2022 Remote Sensing  
rice mapping based on phenology-based approaches.  ...  Here, we compare the effects of data availability of different sensors in the critical phenology phase, thereby supporting paddy rice mapping based on phenology-based approaches.  ...  Thus, advanced satellite imagery (Sentinel-1/2) and multiple data fusion are necessary for the further extensive application of pixel-and phenology-based rice mapping in the whole China, which will alleviate  ...
