传统的水深测量方法是利用测量船上安装的测深设备和定位设备测出水域各点的水深。用遥感方法进行水深反演,基于OLI遥感影像对错戳龙错盐湖进行水深反演研究,确定OLI4波段是研究错戳龙错盐湖遥感水深反演的最佳波段,建立了此盐湖的水深遥感模型。经过对遥感数据和实测点数据的回归分析,建立了拟合方程。根据拟合方程对水深进行反演,反演结果与实测结果基本一致,从而证明了遥感测水深方法的快速有效性,弥补了传统实测水深方法的不足。
The traditional water depth measurement method is to use the sounding equipment and positioning equipment installed on the measuring ship to measure the water depth of each point in the water area. Remote sensing method was used to perform water depth inversion. Based on the OLI remote sensing images, the water depth inversion was performed on the wrongly sighted Longshen Salt Lake. The OLI4 band was the best wave band for studying the water depth inversion of the wrongly smelted Longshen Salt Lake. model. After regression analysis of remote sensing data and measured point data, the fitting equation is established. According to the fitting equation, the water depth is retrieved, and the inversion result is basically consistent with the measured result, which proves the quick and effective method of remote sensing water depth and makes up for the shortcomings of the traditional measured depth method.
