Warboy, Does OpenXcom use the same coordinate system for the globe as the original game or did you all remap it in order to make navigation plotting easier? -Tycho (talk) 23:20, 6 August 2015 (EDT)

we converted them in most cases from xcom units into degrees, the in-game coordinate values are actually the same as the ones used on google maps, which makes it pretty easy to locate cities/etc. and add them in to the rulesets.--Warboy1982 (talk) 05:32, 8 August 2015 (EDT)

Thanks for the info. For a while, I was investigating the navigation code to eventually fix the Great Circle issue in the original game. I got a working formula but the output for the degrees of heading were never as expected. I looked at what formula OpenXCOM used but it seemed fundamentally the same, so I wondered if you all were using your own map data. -Tycho (talk) 08:28, 8 August 2015 (EDT)

we actually wrote some code to convert all the original data into our format, and we use the world.dat file for the polygons. the only thing we really took liberties with were the region zones. we closed the hole near australia in UFO and 99% of the holes in TFTD (i'm still working on those). you can use debug mode to project all the zones/countries/mission zones on the geoscape in real-time if you wanna make comparisons, or one of our forum members, Falko, made a python script [1] to parse it all and give you a cartesian perspective.--Warboy1982 (talk) 03:59, 9 August 2015 (EDT)
