I came across this question on EE:
The solution suggested on the last comment of the thread works fine for the specific N-W-E-S coordinates mentioned in the post.
When I try to use the same method to plot points on a larger map, that is, Entire world map, the equation does not work.
I am using the following link to create vector:
N=90, E=180, S=-90, W=-180
This gives me the map of whole world.
As mentioned in that post, I am using PHP to generate Latitude/Longitudes.
Is anyone here able to help me find the right solution?
At the end of the day, I want to plot X and Y co-ordinates on the Image of World Map using Latitude and Longitude as the only inputs.
Thanks a lot.
