Okay, let's try for a simple explanation! Imagine you have a big piece of paper and some crayons. Pretend that the paper is a map of Bangladesh - which is a country far away, on the other side of the world.
Now, what do you think we should draw on the map? Maybe we can draw big cities like Dhaka, Chittagong, and Khulna. These are places where lots of people live, so they are important to show on the map.
But there's more! We can also draw some rivers like the Brahmaputra and the Ganges, which are really big and flow through Bangladesh. We can draw some mountains and hills too, like the Chittagong Hill Tracts.
Now, when we look at the map, we can see all these different things. We can see where the cities, rivers, mountains, and hills are located in Bangladesh. That's what mapping is - it's making a picture of a place so we can understand it better.
But there's one more important thing to know. When we draw a map, we need to make sure it's accurate. That means we need to use measurements and tools to make sure everything is in the right place. We don't want to draw a river where there isn't really one!
So, mapping Bangladesh means making a detailed picture of the country, with all its different parts in the right place. It helps us understand the geography and landscape of Bangladesh, which is really important for things like planning where to build roads, homes, and businesses.
