The waterways built in the seas and oceans play an important role in shaping the global economy. Every day, a large number of logistics are imported and exported from one country to another through large ships. It is worth noting that when we have to go to different places, we find out about the routes with the help of Google Maps. How do big ships find their routes in the seas? Do you know about this? If not, then today we are going to tell you about this. Where do the ships have to go in the sea? All this is found out from the navigational chart. These navigational charts are made after conducting a hydrographical survey. Hydrographical survey is a subject of strategic importance for countries along with navigation.
The navigation chart that is prepared with the help of hydrography data, not only the surface of the sea but also the information inside it and up to the bottom is studied in detail.
Important for national security
Countries that have detailed hydrography data of their maritime boundaries are very aware of their maritime boundaries, which is very important for coastal and national security.
Important for scientific research
Along with national security, hydrography data is also very important for scientific research. With its help, we can study the oceans and find out the impact of climate change on them.
Apart from all this, hydrographic information also has a huge economic dimension. A country can earn a good amount of foreign currency by providing electronic data to ships passing through its waters through hydrography data.
