High-Resolution Water Body Extraction Dataset Based on Gaofen Satellite Imagery

This dataset is based on Gaofen satellite imagery and is specifically designed for urban built-up area water body extraction and subsequent rapid water quality assessment tasks. It contains high-resolution (2-meter) satellite imagery data along with corresponding annotation information. The dataset covers water body areas in multiple districts of Shenzhen, with the aim of supporting water body extraction and water quality analysis research. The dataset consists of the following main components:Imagery Data: The dataset includes high-resolution satellite imagery of urban built-up areas, with a broad coverage range and high spatial resolution (2 meters). Each image has been pre-processed to remove clouds, shadows, and other influencing factors, making it suitable for water body extraction and other remote sensing analysis tasks.Water Body Annotations: The dataset provides manually annotated water body areas for each image, with high annotation accuracy, intended to offer precise training and testing data for water body extraction tasks.Urban Environmental Features: The dataset includes environmental feature information of various urban built-up areas (e.g., terrain, vegetation cover, urban buildings, etc.), which aids in water quality analysis and model training. By incorporating geographical detectors, it analyzes the impact of environmental factors on water quality changes, providing multi-dimensional tools for water quality assessment.Data Format: The imagery data in the dataset is stored in PNG format, while the annotation data is also provided in PNG format.Data Usage Instructions: The dataset supports various research tasks, including water body extraction, water quality assessment, and urban water environment analysis.
