We are using the real world map as the game world map ; And the entire game goes on in a single world map in which all our players will interact with each other. So we need a big world map that can hold the entire objects of all the players. So to create a big map like this we need to scale the map. If we chose a map with low resolution , when we scale it it would be catastrophic . So to prevent this we need a base map with high resolution, sharp and well defined edges. For this we downloaded the map from NASA. We will now convert it to black and white and scale it to our needs.
