Geoms is a way for grown-ups to talk about pictures of our planet Earth that we take from space. It helps us understand what information we need to share about the pictures and how we can share it with other people.
Think of it like sharing your own drawings with your friends. You would tell them what you drew, what colors you used, and how you made it. The same goes for pictures of Earth. Scientists need to share information like where the picture was taken, what it shows, and how it was taken.
Geoms is like a set of rules that grown-ups agreed on so that they can all share information about Earth pictures in the same way. This way, they can all understand each other and work together to learn more about our planet.
