云南省1：25万水系数据（2014）

本数据集根据区域基础地理信息资料扫描矢量化并结合遥感解译获得，包括云南省内长江、珠江、元江、澜沧江、怒江、等一二级水系，本数据集里数据属性表共有两个字段。字段1：水系名称，数据类型为字符型(80)； 字段2：水系类型，数据类型为字符型(50)。主要应用于地理学、经济统计等相关领域研究

This dataset was developed through raster-to-vector conversion of regional basic geographic information data combined with remote sensing interpretation. It covers first- and second-order river systems within Yunnan Province, including the Yangtze River, Pearl River, Yuanjiang River, Lancang River, and Nujiang River. The dataset's attribute table includes two fields: Field 1: River System Name, with a character string type of maximum length 80; Field 2: River System Type, with a character string type of maximum length 50. It is primarily used for research in relevant fields such as geography and economic statistics.
