Terrain Mapping in Northern Latitudes

Hey IF Devs and any others involved. I know that as recent as last year we had terrain in the area of Anchorage and similar areas. I am just wondering if someone can clear up the Latitude Limit for the Terrain Map in Infinite Flight.

Has anyone else experienced similar lack of terrain in Northern Latitudes.

See this blog article in reference to the northern terrain:

The guy from anchorage is now listening intently

Where was this? I need to see. I hope it’s true! 😳 🏔

Thanks for the article. Very informative. I hope we get this terrain soon as the event I hosted tonight into PAKP was a complete and utter failure. Lolol


Having full terrain coverage would be amazing, I really wish we could get that, but I don’t think it’s going to be something that is possible, at least in the near future.

A comprehensive data set of 3D topography for the entire Earth north of lat 60 has been accomplished in the last few years thanks to the so-called ArcticDEM Project. Perhaps this is a viable way forward. But what the cost for use by a commercial enterprise like IF would be, and the inevitable technical issues are questions.


I fly the NWT/NUNAVUT most of the time and Really does need worked Most airport runways in the Northern airspace are in Magnetic True and the terrain is right off. I live in Lutselk’e. And weird too my RWY headings should be in True. There is no high hills or elevated areas including the Valley. Near Deline and Nahanni Butte should be mountainous areas
Fort Smith has No Apron area at the Aerodrome so you have to start on the Runway (needs reworked @Ecoops123 )
The Arctic regions are great areas to see and would look a lot better if more enhanced. Most Long haul flights from the south travel through Canadian Arctic regions too!…

Kind of an aside, but you can probably thank the Challenger disaster for this. It’s not directly related necessarily, but the Space Shuttle was planned to launch from Vandenberg near LA as a secondary launch facility. Vandenberg would have allowed the Shuttle to reach polar orbits that took them over the poles. Vandenberg Space Shuttle operations got canceled for a few reasons, but largely due to the Challenger disaster causing a major reshuffle of the program. Instead Kennedy Space Center stayed the sole launch facility available to the Shuttle and from there they could reach at most a 62-degree inclination orbit. (the degree inclination of the orbit corresponds to the highest degree latitude reached) Though the mission they did the terrain map on used a 57-degree inclination because it allowed them to be higher which was beneficial to the mission profile. If they had been able to use polar orbits they likely would have since it would have allowed near-complete global coverage.

So yeah, that’s how a poorly designed o-ring on a solid rocket booster not only killed 7 astronauts but now means you can’t get terrain data above 60 degrees north and south in your mobile flight simulator.


I did not expect a discussion about terrain mapping north of 60 degrees to turn emotional. Thanks a lot.


Yea. Like seriously

Sorry, didn’t mean to be all downer lol

Just thought it was an interesting side story about the unforeseen knock-on effects of something you wouldn’t even expect to be related. To be fair some other factors were starting to add up that may have led to SLC-6 at Vandenberg not being used for the shuttle anyway, but they were so far a long they likely would have tried to overcome those if the whole program hadn’t been reshuffled and had to divert a lot of funding.


KPIT moment

  1. when someone asks something and you respond with a block of text that is simultaneously barely tangentially related but also mega interesting

This is a certified KPIT moment.


I mean I’ll take it lol
