1:5万我国海岸带现势高分辨率红树林空间分布数据(2017年、2019年)
收藏资源简介:
结合面向对象分割和目视解译方法,本数据集使用覆盖中国红树林分布区的235景高分影像,采用相同解译流程和标准完成了2017年中国红树林分布。在Albers等面积投影下,统计中国红树林面积为22503 ha (除港澳台外)。为了进一步提高数据精度和数据时效性,使用Sentinel-1/2影像和AW3D30地形数据完成了基于遥感分类的2019年中国红树林分布数据。在相同方式下,统计中国红树林面积为27053 ha(包含港澳台)。
Combining object-oriented segmentation and visual interpretation methods, this dataset utilized 235 scenes of high-resolution imagery covering China's mangrove distribution regions, and produced the 2017 mangrove distribution map of China following a unified interpretation workflow and standards. Under the Albers Equal-Area Projection, the total mangrove area in China was calculated to be 22,503 ha, excluding Hong Kong, Macau and Taiwan. To further enhance the data accuracy and timeliness, this dataset compiled the 2019 mangrove distribution data of China via remote sensing classification using Sentinel-1/2 imagery and AW3D30 topographic data. Following the same workflow, the total mangrove area in China was calculated to be 27,053 ha, including Hong Kong, Macau and Taiwan.
