Hi list!
Sorry, I'm OT, but I don't know other one that (hopefully!) can help
me...
So, my problem: I have a map, generated from Tiles (generated from OSM,
but this is not very important).
The map is NOT the whole word, just a little part.
In my currently test case, about 2°x2° and this is 1792x1536 pixel.
I need to calculate the X,Y position starting from the coordinates
(latitude, longitude).
I searched many procedures in Internet, but I cannot locate a marker at
the wanted place...
I tried to ignore that the word is almost a sphere and calculate the X,Y
as this is flat (X and Y are the size of the map related to the delta of
coordinates), but the position is always wrong.
Now, I'm not very good (AKA: very bad!) in geometry, so I really don't
know how to solve my problem.
I'm working in PHP, but a generic example of the procedure is enough.
Can someone help me?
Thanks a lot
