loading map

[blv]

Hi,
I'm working on a real time strategy game and I'm wondering what the best way to load a map from a file would be? It would be a map similar to warcraft 3 style and I would like to make a map editor in the future. I saw in a couple different tutorials ways of doing this I just wanted to make sure to use the easiest most efficent way of loading and rendering.
Thanks!

i don't think there is no more efficient map loading than the other. considering there is so many open souce ,why not just grab one and go on to use it. And later on, in the case you don't satisfy the performance of loading, do some optimilition yourself, it's great way to learn than sit here comparing this lib with the others.
First thing, make it work,then make it better.

my 2 cents
