I'm looking for a rasterized world map using the EPSG4326 projection, but haven't been able to find any ones online (or at least decent quality ones that appear that the top left does correspond to -180, 90). Perhaps I don't know what to search for.
Can anyone point me to a resource with such a pre-rasterized image?
If not, how would I go about producing such an image?
lat
andlon
in degrees andimg_width
/img_height
in pixels,x = (lat + 180) / 360 * img_width
andy = (lon + 90) / 180 * img_height
. It looks like what you linked may be exactly that. I'm downloading it now. Thanks for the suggestion! If you post an answer I'll accept it.
