水下位置信息模拟数据

数据集为模拟数据，包含所属国家、经度、纬度、水深等信息。数据具有实时，快捷，持久的特点。收录了全球30万余条自然和人工河流、湖泊、水库、水渠等水系实体数据。水体作为自然资源调查、监测管理的空间对象，赋予统一的实体代码有利于准确测绘、监测变化和落实责任，将极大地方便今后开展水资源管理、国土空间规划、灾害应急和政府管理与决策等工作。除完成编码以外，该项目还理清了汇流关系，完成河流分级、流域划分及相应水工设施处理，协调集水区单元界线与河流高水界关系等。

This is a simulated dataset containing information including the affiliated country, longitude, latitude, water depth and other relevant attributes. The dataset is characterized by real-time performance, high efficiency and long-term sustainability. It covers more than 300,000 hydrological entity records worldwide, encompassing natural and artificial rivers, lakes, reservoirs, canals and other water system features. As spatial objects for natural resource investigation, monitoring and management, assigning unified entity codes to water bodies enables accurate surveying and mapping, change monitoring and responsibility fulfillment, which will significantly facilitate future tasks including water resource management, territorial spatial planning, disaster emergency response, government administration and decision-making. In addition to completing the entity coding work, this project has also clarified confluence relationships, completed river classification, watershed delineation, corresponding hydraulic facility processing, and coordinated the relationship between catchment unit boundaries and river high-water boundaries, among other tasks.
