Abstract

Bathymetry is the method can be used to conduct a hydrographic survey. The method itself already evolve from time to time. The traditional way of bathymetric survey is using a single rope and single point checked. Besides, it has a huge limitation where it only can check a single point at a time different from the modern method like using Light Detection and Ranging (LiDAR) or sonar. These kind of new method is more effective than the old method because there is no limitation of point checked. The new method produced wider data result and the resolution for the data also higher than the traditional way. Not only that, the modern method also easy to use and the data obtained more accurate. Hydrographic survey is very important to estimate or observe the underwater terrain for the specific survey area. Hydrographic survey also can be used to provide the underwater map where it allows us to determine what is and is not safe, seafloor mapping is an important technique for regulating underwater resource exploration, extraction, and equipment. Other than that, bathymetric survey assist in ensuring that ships can manoeuvre safely and that human-made structures on the ocean floor are secure. Every bathymetric survey need a tool to ensure the study is successfully done. As this research is using the Smart Deeper Sonar device where this device is using the Compressed High-Intensity Radiated Pulse to transmit the sonar frequency. This device also has a built-in Wi-fi where we can connect our smartphones or other device to tracke the data from the device. The study area is Malacca state. Thus, this study is focusing on producing the bathymetry maps for the Malacca River and the accuracy of Smart Deeper Sonar Device.
