How to Determine the world map size in pixels given this data?
Map size of a particular area say, for example:
Makati city, Philippines with bounds:
Top-Right: 121.0281, 14.56497
Bottom-Left: 121.0144, 14.54637
Image size: width="4095px" height="4095px"
Scale: at zoom level 17 | 1:4,000
Now my question is... how can I know the size of the world map in pixels using these available data?
I'm still new to geographic information systems.... so please if possible make it understandable for a novice like me... :)
