Multimedia cartography is when people use different types of media, like pictures or videos, to create maps.
A map is a picture with lines and symbols that helps you understand where things are in the world.
Multimedia cartography helps us understand maps better by adding more types of information to them. For example, you might see a picture of a mountain on a map, so you know that there is a big hill in that place. Or you might see a video that shows what it's like to drive down a road, so you know what the road looks like before you get there.
Multimedia cartography can help us learn a lot about the world around us. For example, we can use it to see pictures of what different places look like, or to learn about different cultures through videos.
So, imagine a big picture with lots of different pictures and videos on top of it. That's what multimedia cartography is all about!
