This data set includes the basic data of the capital of the Yellow River Basin, the city level of the Yellow River Basin, the main stream of the Yellow River, the Yellow River Lake, the Yellow River tributary, the river, the railway, the highway and the key tributaries. The data storage format is SHP. The national basic data set is from the 1998-2002 Yellow River Basin Soil and water conservation remote sensing survey project. The TM satellite image from 1997 to 1998 is the main information source, and is obtained by the method of human-computer interaction interpretation.
This data set is obtained by remote sensing image interpretation and processing.
The TM satellite images from 1997 to 1998 are the main information sources in this dataset. The remote sensing images are preprocessed by radiation correction, orthorectification, fusion and mosaic. The monitoring data of the whole basin and sub Administrative Region (province, prefecture, county), type area and sub basin are obtained through image interpretation in the form of man-machine interactive interpretation and geographic information coding database, which has good accuracy.
The data set is in the charge of professionals in each stage of acquisition and processing, and the data quality is good. The remote sensing images are processed by radiation correction, orthorectification, fusion and mosaic, and the manual interpretation results are reviewed and corrected.
