1986-2015年全球30米分辨率城镇用地扩张占用水体时空数据集

全球30米分辨率城镇用地扩张占用水体时空数据集

数据简介

2026·GRDC

    本数据集提供了1986—2015年全球范围内30米分辨率的城镇用地扩张占用水体时空数据，用于反映近30年来全球城市扩张对水体的直接占用情况。数据基于高分辨率遥感影像和全球地表水数据集，通过分析城镇用地变化与水体分布的时空叠加关系，提取了城镇用地扩张过程中占用的季节性水体和永久性水体信息。

    该数据集以矢量格式存储，数据量约1.69GB，坐标为Krasovsky_1940_Albers，覆盖全球范围，可服务于水资源保护、生态监测、城市规划及可持续发展等研究领域，为全面认识人类活动对水生态环境的影响提供基础数据支撑。
数据信息

  • 数据来源：地球资源数据云

  • 数据范围：中国陆地范围

  • 空间分辨率：30m

  • 坐标系：Krasovsky_1940_Albers

  • 数据集优势：数据集包含1986—2015年全球城镇用地扩张占用水体的空间分布信息，以矢量格式存储，采用Krasovsky_1940_Albers投影。数据属性字段中Class表示占用水体类型，其中“0”代表季节性水体，“1”代表永久性水体。用户可直接使用GIS或遥感软件进行读取、分析与可视化。
