A dataset of mangrove forests distribution in Leizhou Peninsula during 2019-2023
收藏资源简介:
This dataset uses Sentinel-2 constellation cloud free images, extracts coastal buffer zones, selects suitable scale segmentation images, and uses object-oriented random forest method to classify and extract mangrove forests shapefiles. Finally, threshold optimization is performed and organized. The dataset includes shapefiles of mangrove forests in nine districts and counties of Leizhou Peninsula in 2019, 2021, and 2023. The file naming format is "district name+mangroves_year", using the WGS_1984_UTM coordinate system, with a spatial resolution of 10 meters, and totaling 61MB of data volume.
本数据集采用哨兵二号(Sentinel-2)星座无云影像,通过提取海岸缓冲带、选取适宜尺度的分割影像,采用面向对象随机森林方法完成红树林矢量Shapefile(shapefiles)的分类与提取工作,最终完成阈值优化与数据整合。本数据集涵盖雷州半岛9个区县2019年、2021年及2023年的红树林矢量Shapefile文件;文件命名格式为"district name+红树林_年份",采用WGS_1984_UTM坐标系,空间分辨率为10米,总数据量达61MB。
