Have you ever seen a map before? It's like a big picture of the world. But did you know that sometimes maps can be changed on purpose to hide or show certain things? That's called cartographic censorship.
Let's say there's a country that's in a war with another country. The leaders of the first country might not want people to see where their military bases are on a map because it could give an advantage to the other country. So they might change the map to make it look like there are no military bases there, even though there really are.
Or let's say there's an island that's really important to a group of people, but another group of people wants to take it away. If they control the map, they could draw the island as being part of their own land, even though it's not really.
Cartographic censorship isn't always bad though. Sometimes maps are changed to protect people's privacy or keep sensitive information secret. It's important to remember that maps aren't always 100% accurate or truthful, and we have to be careful when using them to make decisions.
