石羊河流域基础数据集

石羊河流域信息系统专题数据集是亚洲开发银行援助的技援项目“甘肃省优化荒漠化防治方案”的成果之一，包括document、investigation_point、maps、photo和spatial等5个文件夹，每个文件夹又包含若干文件。其中document文件夹包括目标设计、数据处理、专题总结报告和投影信息等文档:gpspoint文件夹包括gps根据不同目的而采样的以shapefile点格式记录的文件:maps文件夹又包含chinese、english和fonts文件夹,前两个文件夹分别代表中英文的14幅以A4幅面大小和pdf格式存储的地图，而fonts包含一些特殊的字体:photo文件夹包含野外调查的以bmp格式存储的数码像片:spatial文件夹包含数字高程模型的dem文件夹、甘肃省和河西走廊轮廓图的gansu文件夹、站点数据文件生成shapefile文件的generate文件夹、各种地理要素的栅格数据的grid文件夹、遥感影像的image文件夹、原始站点文本数据的meteoHydro文件夹，和各种地理要素的矢量数据的vector文件夹。The Shiyang River Basin Information System Thematic Dataset is one of the outcomes of the technical assistance project "Gansu Desertification Prevention Plan Optimization" aided by the Asian Development Bank. It comprises five folders: document, investigation_point, maps, photo, and spatial, with each folder containing multiple sub-files. The document folder includes documents such as target design, data processing, thematic summary reports, and projection information. The investigation_point folder contains files recorded in shapefile point format, which are sampled by GPS for different purposes. The maps folder contains three sub-folders: chinese, english, and fonts. The first two folders respectively store 14 A4-sized maps in PDF format for Chinese and English versions, while the fonts folder contains some special fonts. The photo folder holds digital photos in BMP format from field surveys. The spatial folder includes the following sub-folders: the dem folder for digital elevation models, the gansu folder for the outline maps of Gansu Province and the Hexi Corridor, the generate folder for generating shapefile files from station data, the grid folder for raster data of various geographic features, the image folder for remote sensing images, the meteoHydro folder for original station text data, and the vector folder for vector data of various geographic features.
