Classification of nighttime light types in China’s nature protected areas based on SDGSAT-1

International Journal of Digital Earth
Protected areas play a crucial role in preserving biodiversity and providing ecosystem services. However, the encroachment of nighttime light increasingly exacerbates light pollution in these regions. Previous studies using remote sensing to assess light pollution in protected areas have primarily relied on single-band Nighttime Light (NTL) imagery ...

Retrieval of Total Suspended Matter Concentration Based on the Iterative Analysis of Multiple Equations: A Case Study of a Lake Taihu Image from the First Sustainable Development Goals Science Satellite’s Multispectral Imager for Inshore

Remote Sensing
Inland waters consist of multiple concentrations of constituents, and solving the interference problem of chlorophyll-a and colored dissolved organic matter (CDOM) can help to accurately invert total suspended matter concentration (Ctsm).

Pre-Processing of Inner CCD Image Stitching of the SDGSAT-1 Satellite

Applied Sciences, 2022
Spliced optical satellite cameras suffering from low stitching accuracy are influenced by various factors which can greatly restrict their applications. Most previous studies have focused on the geometric precision of stitched images, which is influenced by the stitching consistency and the relationships between different inner CCD (Charge-Coupled ...

Ship detection and identification in SDGSAT-1 glimmer images based on the glimmer YOLO model

International Journal of Digital Earth, 2023
ABSTRACTRemote sensing technology has been widely used for marine monitoring. However, due to the limitations of sensor technologies and data sources, effective monitoring of marine ships at night remains challenging. To address these challenges, our study developed SDGST, a high-resolution glimmer marine ship dataset from SDGSAT-1 satellite and ...
