How have maps changed?

here are some reason:

maps were once drawn on clay tablets carved on the ground and drawn on mark..... now map are ouvisouly on paper.

also maps in the earliest ages were not accurate because mapmakers didnt know the "correct" knowledge.... now on maps we know the correct knowledge.

also ptomley didint know mathamatics and the correct knowlegde and he sometimes left empty spaces and warning because onestly he didnt know what the heck what was there.....
