  "textContent": "A high-precision waterway reconstruction method based on a multi-satellite source information coupling is provided. The method includes a determination method for a waterway section, a reconstruction method for a basic waterway section high-precision coupling, a reconstruction method for a fixed waterway section coupling, and a reconstruction method for a river reach waterway terrain. The method fills the gap of surveying and mapping of the waterways based on satellite remote sensing information, extremely improves the perpendicular precision and planar precision of the existing digital surface model of satellites for river waterways, and provides decision support for a water-related emergency rescue in areas lacking data.",
