呼兰河流域1:25万水系数据集(2012年)
收藏资源简介:
本数据集包括呼兰河流域范围内的线状河流、面状河流、湖泊及水库等水体分布数据。将Landsat遥感影像进行解译,得到黑龙江省水系分布,并与黑龙江省地图,交通图融合,配准,矢量化制作,并且数据利用5万地形图校正,服务于从事农业生态研究的学生和科研人员。http://northeast.geodata.cn/special/dataRetrieval.html
This dataset contains water body distribution data including linear rivers, areal rivers, lakes, reservoirs and other water bodies within the Hulan River Basin. The water system distribution of Heilongjiang Province was obtained by interpreting Landsat remote sensing images. Then, the data was integrated, registered and vectorized by combining with the map of Heilongjiang Province and traffic maps. Additionally, the dataset was rectified using 1:50,000 topographic maps. This dataset serves students and researchers engaged in agricultural ecology research. The data access link is http://northeast.geodata.cn/special/dataRetrieval.html
