黄河三角洲各亚三角洲体发育数据(1889-2000年)
收藏资源简介:
本数据集是依据1855年以来黄河尾闾10次大的流路改道过程,结合历史时期海岸线资料生成。1855年海岸线根据法国1863年出版渤海南部海图调制;1934年海岸线参考‘1934年黄河口区海域深度数据图(根据日本1934-1938年出版渤海湾和莱州湾海图调制)’和美国ARMYAIRFORCE1945年生产的渤海海图;1953年海岸线采用1957年地形图数据;1976年以后海岸线数据依据遥感影像。其中,1889年、1897年、1904年和1929年的海岸线数据精度较低;1855年、1934年、1953年和1964年的海岸线系根据专业图件数字化所得,精度较高。
This dataset was developed based on the 10 major course diversions of the lower (estuarine) reach of the Yellow River since 1855, combined with historical coastline data. The 1855 coastline was compiled from the southern Bohai Sea nautical chart published by France in 1863; the 1934 coastline referenced the '1934 Yellow River Estuary Sea Area Depth Data Map (compiled from nautical charts of the Bohai Bay and Laizhou Bay published by Japan between 1934 and 1938)' and the Bohai Sea nautical chart produced by the U.S. Army Air Forces in 1945; the 1953 coastline adopted topographic map data from 1957; and coastline data after 1976 were based on remote sensing imagery. Among these, the coastline data for 1889, 1897, 1904 and 1929 have relatively low accuracy; the coastline data for 1855, 1934, 1953 and 1964 were digitized from professional cartographic documents, with relatively high accuracy.
