Long/Lat coordinates of .tcc files

Hi Martin,

regarding .TTC files:

The 2 images below show the situation for level 5, a very basic level. Please note, that aerofly uses the lower left corner, the lonlat minimum values.

Hope this IPACS code can help you to calculate the tile borders:

const double tmcoordinates::WorldGridConstantA = 2.3311223704144;

tmvector2d tmcoordinates::WorldGridFromLonLat( const tmvector2d& lon_lat )
{
  double x = lon_lat.x / TM_PI;
  double y = lon_lat.y / TM_PI;

  y = tan( WorldGridConstantA*y ) / WorldGridConstantA;
  x = 0.5 + 0.5*x;
  y = 0.5 + 0.5*y;

  return tmvector2d( 65536.0*x, 65536.0*y );
}


tmvector2d tmcoordinates::LonLatFromWorldGrid( const tmvector2d& world_grid )
{
  double x = world_grid.x / 65536.0;
  double y = world_grid.y / 65536.0;
  
  x = 2.0*(x-0.5);
  y = 2.0*(y-0.5);
  y = atan(WorldGridConstantA*y)/WorldGridConstantA;

  x *= TM_PI;
  y *= TM_PI;

  return tmvector2d( x, y );
}

ok so i got this far....Help !!

Not sure why was ment to be the whole island but now looks like a sunny island with a shiny new photo

of the whole island in the middle,if i delete file i take it the game will be fine?

and i used the geoconverter helper tool,i did try fix the pic with aplha layer maybe that was a mistake

still the nice bit looked really nice in vr

Hi Player1,

I think, the alpha layer is not the problem.

I assume the blurry side is the original texture, where as the upper right part is the converted island texture.

I suppose you set the parameters [write_images_with_mask][false].

So I guess your frame is too small, only one tile has been generated.

A lot of assumptions here, but I don't have enough information to be more precise.

thanks i was trying to cover the whole island with new pics

i draw fset box over whole island with setting as

FSET

earth service : virtual earth

scen compiler fsx

area snap off

create masks no

comp scenery no

use cache no

GEO CONVERT HELPER

LEVEL 9 11 12 13 14

Sorry im new to this dont understand what im doing wrong

so do i need to have masks on or off?

and comp scenery on or off?

dont understand why it only did one tile

thanks for your help

and all who have taken time to read my post

Hi Player1,

you're welcome, we try to figure out the problem.

Your FSET settings are correct.

Now we concentrate on your geo convert helper settings.

Can you provide a screenshot or explain your settings?

Or can you attach the config...TMC file?

This seems to be a part of northern Scotland?

Perhaps it is something different.

just to check, assuming your algorithm is for Level 15... wrong ? So if I want to introduce "Level" variable in your code could I write something like this ? (don't worry about C++ syntax please )

sorry this question had no place at all here... I misunderstood the purpose of this algorithm...

Hi.

For Rodeo.... the Profi !

I must understand the Map and Level Format in Aeroflight FS2 !

my brain...

Is this correct for my brain where the Levels in Aeroflight as my picture say?!!?!?

For what is Level 15 ?

This Level was not generated.... he works in Convert tool, but no "15er" ttc files was generated.

And... i experiment with the folder from World Scenery Image Files.

When i delete map Files 1 to 4 or 5 i see in the World map nothing or individual not complete World Map.

When i delete Map 7 to 12 i see the world map, but the ground area are very rough / not fine texture....

And last question.

for what are the .raw Images ?

Put in who?

Please ...teaches me of a better one

Regards

ULI

Hi Uli,

I'm not familiar with the World Scenery Maps, so I can only refer to the aerofly levels.

The levels represent aerial images processed for different resolutions, which will show up in different flight levels (heights).

In general, your description from rough to fine is correct.

The level 14 conforms roughly with 1m ground resolution.

Level 15 is only meaningfull, when you have aerial images with a clearly higher resolution than 1m.

Regards

Rodeo
