Limitations of extraction

What's in the WZ files:
- Map data and layouts

Fiel,
I am trying to see if your extractions have map data that will allow me to calculate a ratio for (mob spawn / usable map area) for every map in the game. "Mob spawn" meaning the max number of mobs that can spawn in any given map and “Usable map area" meaning the total area that a character can move around on any given map (possibly the pixel length of all platforms in a map).

Question 1
Can you see/provide how many of each type of mob spawn in a given map? I think I saw you do this once on the new "chimney" maps in the haunted house....
Question 2
Is it possible to see some raw map data that would allow me to pull out the "Usable map Area" information?

Thanks for your time....
