How to draw coastal bathymetry with the help of optical multispectral satellite captured imageries ?
How one can measure the depth of sea water by the help of inexpensive satellite captured multispectral data.
Drawing bathymetry profiles of the coastal regions is always a challenge due to the requirement of buying expensive LIDAR or sonar-based data. Developing countries found it hard to use such data for analyzing the bathymetry of the Ocean. Especially the shallow coastal zones where 10% of the World’s population stays those zones are very hard to penetrate even by sophisticated LIDAR satellites. This article shows a path where you can use inexpensive satellite capture multispectral imageries to create bathymetry of coastal zones up to 30m deep. Read the article by clicking to Geo Awesome and learn how you can draw bathymetry of the coast with optically captured satellite imageries. The same method can also be used for creating bathymetry for wetlands or rivers where accessibility of LiDar or Sonar-based satellite is minimum.
“The shallow water zones near the coast are home to around 10% of the world’s population, playing host to many megacities. These low-lying regions are also of the utmost importance for industrial applications—such as the safe navigation of ships—as well as for coastal protection and management. Coastal areas are also highly dynamic, particularly vulnerable to natural and human-induced changes, impacted by factors including erosion, extreme weather events, sea-level rise, and population movements. Continuous monitoring of the world’s coasts is a necessity.
Gathering bathymetric data for shallow coastal waters has always been a challenge as traditional methods such as sonar or LiDAR are time-consuming and expensive to carry out. As a result, for a large number of these coastal regions, such data is either unavailable or decades old.
One of the promising technologies to bridge this information gap is satellite-derived bathymetry (SDB), which is using multispectral optical data to estimate the depth of near-shore waters.”
