Research Bathymetry Mapping of Shallow Water Areas around Islands in the Truong Sa Archipelago by Deep - Remote sensing technology

Abstract

Satellite image data is being researched and applied effectively in the survey and
establishment of bathymetry mapping in shallow water areas in both time and human terms. Remote
sensing techniques contribute to rapid updating of topography, timely assurance of civil and military
operations such as maritime safety, environmental security and rescue, warfare in the military,
especially the ability to remotely monitor disputed areas. The article experiment with the Stumpf
algorithm to estimate the shallow water depths on the Spratly Island by Landsat 8 image. The
correlation coefficient of the model R2 is 0.924; RMSE is 0.99m. In addition, the results are compared
with the map data of C-map and use 12 actual test points scores to evaluate the accuracy of the model.
