A PLANET ALREADY MAPPED
Why Measurement Is Not Yet Human Geography
Mars is not blank.
We already know its shape, terrain and coordinates with extraordinary precision. We have global imagery, elevation models, reference systems and an established vocabulary for many of its most important physical features.
That is an excellent planetary map.
It is not yet an operating geographical map.
The distinction is the starting point for Matlas. Measurement tells us where something is. Geographical maps also helps us organise places, group them, relate smaller areas to larger ones and give different people and systems a shared way to refer to the same ground.
Part I follows that gap through two steps:
Measurement — what do we already know about Mars?
Organisation — what does a civilisation need that coordinates alone do not provide?
The argument is deliberately narrow.
Mars does not need to be mapped again.
It needs another layer between measurement and the humans that settlement will eventually need.
