Cartographer

The Cartographer is Installation 00's map program, similar to Installation 04's Silent Cartographer (Alpha Halo).

The cartographer building is a Forerunner structure on the Ark which features a map room of the Ark's structure when activated.

The purpose of the cartographer building is to show a holographic map which can be used to navigate the massive expanse of area that the Ark is made up of. There are similar buildings as the cartographer building on the Ark which are almost similar shape in exterior and interior on Installation 04 and presumably on all other Halo installations which might have different designs. The map room is somewhat larger than Alpha Halo's cartographer building and also much more open to the outside, showing a wide and huge waterfall.

The building will be ventured later in the game when the player(s) crosses through the Forerunner wall, following 343 Guilty Spark who hacks into the structure to allow him to pass through.
