How Our Earth was Mapped before Satellites?

Imagine drawing a picture of your room without being able to see it, that’s kind of what people did when they tried to map our Earth before satellites.

Long ago, travelers and sailors went on big adventures across oceans. They used the stars in the sky like a nightlight to help them find their way. When they came back, they told others where they had been, kind of like telling stories about new places you’ve visited!

Sometimes, people would draw pictures of what they saw from high up, like from the top of a mountain or a tall tower. These drawings helped show how far apart different places were.

One clever idea was using triangles to figure out distances. If you know how long one side of a triangle is and some angles, you can guess the length of other sides, just like when you try to figure out how far your friend is from the tree by looking at their shadow!

So, people used stories, stars, pictures, and clever math to map our Earth, all without needing satellites or computers! Imagine drawing a picture of your room without being able to see it, that’s kind of what people did when they tried to map our Earth before satellites.
