The map graphics are copyright to MechWarrior Online (c) 2012-2019 Piranha Games Inc. The maps are made by Neteye, with the help of Poly Cat, mr_bear, Capn Cat, Camron Lyraus, Sanjue, daidachi, Volkodav, Not Bob and a bunch of nameless pilots that did a lot of lobby drops to make screenshots.
To set up an updated tool for the MWO Comp community was an idea by Live1991.

You can help to update a map: The best way is to drop in a lobby, with one mech in each lance (of different weightclasses for the ease of knowing which one is Alpha Bravo and Charlie), open the battlegrid after dropping from the dropship and make a screenshot. Higher resolution/zoomed in = more precise maps, also counts for the objectives (you can zoom in the battlegrid). Then upload it somewhere (e.g. imgur, and tell us about it, either via mail or in the MWO Comp Discord.
