Conversions to 2D Map

Conversion of world coordinates to a 2D map texture coordinate (in pixels):

public static Vector2 GetPixelCoordinates( Vector2 worldXZCoordinates, Vector2 mapOffset, UInt16 mapSizeFactor )
{
    return ( worldXZCoordinates + mapOffset ) / 100f * mapSizeFactor + new Vector2( 1024f );
}

This assumes using the basic map textures that are 2048x2048. If you're using the small (1024x1024) map textures for some reason, divide the result by two.

Conversion of map texture pixel coordinates (such as FishingSpot coordinates) to in-game 2D map coordinates:

public static Vector2 GetGameMapCoordinates( Vector2 mapPixelCoordinates, UInt16 mapSizeFactor )
{
    return mapPixelCoordinates / mapSizeFactor * 2f + Vector2.One;
}

Conversion of world coordinates to in-game 2D map coordinates (using the above functions):

public static Vector2 WorldToMapCoordinates( Vector2 worldXZCoordinates, Vector2 mapOffset, UInt16 mapSizeFactor )
{
    return GetGameMapCoordinates( GetPixelCoordinates( worldXZCoordinates, mapOffset, mapSizeFactor ), mapSizeFactor );
}

The game truncates the result of this to the first decimal place.

To translate a levels.exd position to an in-game X/Y:

//
// This takes the X/Y, scale and tilescale from levels and converts it to
// and in-game X/Y position, I have not found tile scale in the files
// and it's never not been 50 (50px per tile), its not 100% accurate, 
// tilescale is actually something like 49.951219... (2048/41)
//
public function mapsTranslateXYZToGame($x, $y, $scale, $tilescale = 50)
{
    if ($x == 0 || $y == 0 || $scale == 0) {
        return false;
    }

    $map = 2048 / ($scale / 100);

    $tilecount = $map / $tilescale;

    $x = ceil(round(($x / $tilescale) + ($tilecount / 2),1));
    $y = ceil(round(($y / $tilescale) + ($tilecount / 2),1));

    return [
        'x' => $x,
        'y' => $y,
    ];
}

And finally, to translate an in game X/Y to a levels.exd position which can then be converted to a 2D or Long/Lat:

//
// Translates a X/Y from in-game to a levels output (which can then be translate dto lat/long
// this is quite accurate, not found it to be off at all. Requires map scale
//
public function mapsTranslateGameToXYZ($x, $y, $scale)
{
    $scale = $scale / 100;

    $x = ($x*50)-25-(1024 / $scale);
    $y = ($y*50)-25-(1024 / $scale);

    return [
        'x' => $x,
        'y' => $y,
    ];
}
