Before I receive a salvo of RTFM, let me say that I’ve searched the Forum and read Red Dog’s Nav manual (and his book).
So my question.
On the interactive maps, as you know, the grids are numbered, for example Seoul is in grid 5-2 (or 4-0 in the 4.33 version).
Please explain their function, how numbers are allotted and why do they change. There appears not to be a numerical sequence.
Knowing the quality of Red Dog’s work, I’m sure the answer is there.
So for those itching to say RTFM, if I’ve missed it, just tell me the page number and I’ll be happy to look it up.

The map displays MEF (Maximum Elevation Figures) in each box created by one degree of latitude and 1 degree of longitude. The MEF are the highest known point of elevation in each box. They are given in hundredths of feet, with the large number being thousands and the smaller number being hundredths of feet. For instance 52 indicates 5200 feet.
To stay safe from hitting the ground (in bad visibility for instance) you should stay above that reference by at least 500 feet. MEF + 500feet = MSA (Minimum Safe Altitude) unless you are on a published SID or approach chart which will keep you safe from the terrain.
By the way the above was from one of Red Dog’s manuals, but not one you’ve read, because we haven’t released it yet
Thank you Darkman……right, I understand, the numbers show the highest point in that particular grid.
Why have they been changed in the 4.33 interactive map, Seoul changed from 5200 feet to 4000 feet?

This is just a wild guess, but perhaps the terrain has changed between 4.32 and 4.33?
Would be the most likely reason for it to change between the two maps.
You know, you could be right! ��

Or maybe it was a mystake before and corrected on the new version ;).
not quite a mistake, but a questions of older tools not being accurate enough while the newest tools are way better.
So it didn’t change in the game, the modern computation are more accurate than before and therefore less caution could be applied
Did you reference a newer set of maps? Things change…being actively involved in flight ops, I’ve lived long enough to see runways re-numbered due to shifts in mag-var (yeah…which means I’m old…). So changes in MEF would not surprise me for any or all of the reasons described if the coders used one set of maps as reference back in the day, and more recent ones…er…recently.
Hi Stevie……newer maps?..just the “new 4.33” interactive map.
Old?..I bet I’m older!
California? Drove the Big Sur last year, magic.
(It’s Scary mentioning 4.33, almost expect the thought police to knock on the door)
we don’t reference maps. We refer BMS terrain elevation
I’m assuming you model BMS terrain on something…right? What reference do you use for that?
You’re well traveled, Bayonet…I’ve been though Heathrow,on my way to a couple weeks in Finland and Switzerland, but haven’t managed to spend any goodly amount of time in your part of the Isle…save me a whiskey!

Current information on what is real can differ by source and the limited knowledge of that area at the time. The sim is in a constant state of change while moving towards being as real as it gets. One can go crazy trying to keep up. I think RedDog is doing a great job of keeping up and has a good way of putting things that are real but may not be implemented yet in grey while documenting what is in the sim in black. The documents are for the sim. The sim is doing its best to be real.
That’s not what I was trying to say - only that between the time of the last update and this Reddog’s information may have improved…and he used something better than he had the last time.
I always assume the latest is the best!
