Semantic Segmentation Dataset of Mountain Rivers in Fujian Province, 2024

This dataset collected a total of 2500 remote sensing images of rivers in mountainous areas at the municipal level and downstream river mouths in Fujian Province in 2024 (with a spatial range roughly between 23 ° 30'N-28 ° 20'N and 115 ° 50'E-120 ° 40'E), covering remote sensing images of rivers at different altitudes, terrain, widths, and curvatures (with a spatial resolution of 500 meters). The pixel values of the image are all 1000 × 1000, and Labelme standard software is used to segment and label the water areas in the image. The dataset contains four subfolders, which respectively store the original data image, JSON format labels, mask label images, and visual overlay images.
