黄土高原淤地坝数据集

数据集为黄土高原淤地坝数据，提供包括了淤地坝坝地坐标、坝地面积、淤地坝淤积体积和拦沙量等多个基础数据。数据源来自谷歌地球影像，空间分辨率为0.3-1.0米。数据通过影像收集、影像处理、多尺度分割、分类、河网叠加分析、人机交互识别等多个步骤完成；通过严格的质量检查，数据完整性、逻辑一致性、位置精度、属性精度、接边精度、现势性均符合国家测绘局制定的有关技术规定和标准的要求，质量优良可靠。

This dataset contains check dam data for the Loess Plateau, providing multiple basic data items including the coordinates of dam farmland, the area of dam land, the sediment deposition volume of check dams, and sediment retention capacity, among others. The data is sourced from Google Earth imagery, with a spatial resolution ranging from 0.3 to 1.0 meters. It was generated through a series of workflows including imagery collection, image preprocessing, multi-scale segmentation, classification, river network overlay analysis, and human-computer interactive recognition. After passing strict quality inspections, the data's completeness, logical consistency, positional accuracy, attribute accuracy, edge-matching accuracy, and timeliness all meet the requirements of relevant technical regulations and standards formulated by the National Administration of Surveying, Mapping and Geoinformation, with excellent and reliable data quality.
