Urban Surface Water Mapping from VHR Images Based on Superpixel Segmentation and Target Detection by Qingwei Liu, Yugang Tian, Lihao Zhang, Bo Chen

“…The method includes three steps: clustering water bodies into sparse targets at the object level by an improved scale-adaptive simple non-iterative clustering (SA-SNIC) superpixel segmentation; generating new bands with additional spectral, spatial, and derived features, to increase the dimensions of original data and enhance the separability between water bodies and background covers; and constructing a positive-negative constrained energy minimization multitarget sparse detector to highlight the water bodies while suppressing shadows. …”

Discussion on the effectiveness of landslide hazard identification and factors affecting the effectiveness of LT-1 satellite based on InSAR technology by Junzhe Xiong, Tao Chen, Guangbin Yang, Renru Wang, Man Li, Linglin Zhao, Chunyang Chen

“…Utilizing Stacking, SBAS, and D-InSAR techniques with LT-1 and ALOS-2 data, key findings include: (1) identification of 259 landslides, (2) detection of a major landslide in Nayong County with a subsidence rate of 26 cm/year and cumulative deformation of 212 mm, (3) limited landslide detection in shadowed areas with single-orbit LT-1 data, suggesting the need for dual-orbit monitoring, and (4) LT-1 outperforming ALOS-2 in detecting small-scale landslides in sparsely vegetated areas. …”
