So you've got a solution, above, you got a statement which attests to that fact, the SH3 can not be compared with a standard chart, I suggest you google up a suitable solution.

Yes! the fact is - SH3 can not be compared with a standard chart.

Do you mind explaining how on earth google could solve this issue ?

Google Earth, you see things in another perspective, I have sailed in all the water in the SH3, and there's no getting 'round the world' as it is with Google Earth, I'd probably find a solution, but not just so here, but requires estimates of the mathematical kind, when you wanted to compare in kilometers.

"round the world" was not a problem in SH3 when I made a test mission. Once you run into the end of the map in one side, you show up in another..

Just thinking about all of this puts me in despair

No fear, as there are wheels to be here:

If you get the whole idea, I assume you understand that oval earth can be showned as flat on a paper map but in correct OVAL shaping. However in SH3 earth map is plain square, where the lenght of equator is the same as pole circle for instance. On google earth everything looks ok.

But the question is: If SH3 map is "bigger" than Earth itself we have, is it possible to accordingly increase distances between waypoints accuratly to mimic true distances as if they were in RL, but in game ?

I imagine it is hellova job and yeah, that requests good mathematical skills too

Math was never my mate in school BTW

Frankly I already have this tool that comes together with OLCG2 environment mod. IIRC it's job is an alternative for ZielKursWinkel ?
To calculate speed, course, etc ? I always rely on Zielkurwinkel to get all the data I need. Actually I never bother getting true target course, relying on my own eyes to put my boat on interception course..

But how it is related to nautical miles anyway ?


GUYS! as I already mentioned I might sound strange tonight, cheers
But what the hell are Fridays for ?

Well..one nautical miles,1852 meter, so count...

I want to thank all that were interested in this topic. I have to go out now, so tomorrow or day after, I'll be back to continue discussing it ok ?

I'm temporarily off, to continue after "ressuply" mission

The side I had in mind can be seen in message 39 iirc (Puster Bill's). The OLC2 Gui doesn't have it. It has logarithmic scales (yeah I know, scary magic there ) that allows you to do time/speed/distance conversions easily. Among other things.

This document is a sort of how-to:

1 km Sh3 = ? km RL

The SH3 world is a "Mercator projection" - meaning that the round earth is being projected on a flat surface.
This results in a great deal of distortion in the distances between objects.
for example:
On the round earth it is a voyage of some 3,300 miles (give or take) from Brest France to New York harbor...in the "mercator world" of SH3, that distance is distorted to a whopping 5,300 miles...not quite TWICE the actual distance.

Eg:
A type VII sub would have no problem travelling at an economic cruise speed from Brest to New York and back acting conservatively but in SH3 you would run out of fuel about half way into your return voyage.
Because the SH3 modders could not change the SH3 world from Flat.. to spherical, they had to adjust the in game range of the U-boat by increasing it nearly 3 fold.

Yeah I remember reading about U-boat ranges has been increassed to meet larger SH3 world..

I'm doing some testings ATM. Not something too special but worth a try anyway

Roughly speaking we have an equator of earth that is 40000 km long.
The equator of SH3 earth that is 43154 km long.

So basicly:

40000 km - 100% = 43154*100/40000 = 107.855%
43154 km - x%

So we now know that SH3 world longitude is + 7.855%.

Knowing that we can recalculate distances to meet SH3 scale regarding longtitude:

107.855 x Y /100 (where Y is true distance in KM took from GE for intance)

Does anyone else see an opportunity for an SHIII "Google Earth" mod.

I'm thinking along the lines of replacing the flat SHIII chart with a series of images of an earth globe.

Probably not possible.
