黄土高原地区林区界数据集

本数据集包括六盘山林区界与子午岭林区界，数据存储格式为shp。本数据集通过遥感影像解译加工获得，主要经过了对遥感影像纠正、解译、校验后生成。数据集在获取处理各阶段均由专业人员负责，数据质量良好。遥感影像均经过辐射纠正、正射纠正以及融合、镶嵌等处理，并对人工解译成果进行复核校正。

This dataset includes the forest boundaries of Liupan Mountains and Ziwu Ridge, and is stored in shp format. This dataset is obtained through the interpretation and processing of remote sensing imagery, and is mainly generated after correcting, interpreting and verifying the remote sensing images. All the remote sensing images used have undergone radiometric correction, orthorectification, fusion, mosaicking and other processing, and the manual interpretation results have been reviewed and corrected. Each stage of data acquisition and processing was undertaken by professional personnel, and the data quality is excellent.
