Satellite Bathymetry is a cutting-edge technology that allows us to map the depths of seas and oceans from space. This method offers a modern approach to an age-old practice, shedding light on underwater topography and helping us better understand the world beneath the waves. As with any technological advancement, satellite bathymetry comes with a unique set of benefits and challenges. This article delves into what Satellite Bathymetry entails, its advantages, drawbacks, and way of use in the Online cloud for hydrographers, port authorities, and marine entities- Port Mapper.
What is Satellite Bathymetry?
Satellite Bathymetry is a technique used to measure the depths of the ocean floor using satellites. Unlike traditional methods, which involve sonar equipment on ships, satellite bathymetry relies on remote sensing technology. By analyzing the variations in sea level through satellite imagery, scientists can infer the underlying topography of the ocean floor. According to the British Hydrographic Office, the measurement of sea depth is based on the assumption that deeper areas will appear darker in images than shallower areas.
Like every research method, satellite bathymetry has certain disadvantages.
Considering the characteristic features of satellite bathymetry, which include the low cost of conducting work compared to traditional surveys, large scale and territorial range, location in navigationally challenging terrain, and lack of environmental impact – this leads to a conclusion endorsing the wide use of satellite-derived data in maritime cartography.
We utilize the advantages of satellite bathymetric measurements in Port Mapper. The speed of data collection and the ease of sharing the results of conducted analyses provide enormous assistance to maritime administrators. The system, thanks to the use of analytical & AI algorithms of processing satellite data, is able to estimate coastal bathymetry in optically shallow water. As a result, the system user will have access to current and systemically acquired bottom maps, which will ultimately allow assessing bottom defects (primarily for the sand bottom), the effects of human interference in nature, and assessing the effect of corrective actions or their planning.
Satellite Bathymetry has revolutionized the way we explore and understand the ocean floor. Its cost-effectiveness, wide coverage, and accessibility make it a valuable tool for researchers and professionals across various fields. However, resolution and depth limitations present challenges that need to be considered. As technology advances, we can anticipate enhanced capabilities, paving the way for more detailed and accurate ocean floor research.
