Get the map informations

Hi all, i am actually coding a fully external automated bot and i have no idea how to find the map informations such as the construction grid. I only know where i can find the dimensions. I don't know if it's really possible and if someone have ever found that. If it's impossible, maybe someone know how i could find a database or something that allow me to get all the informations on the maps.
Sorry for my very bad english, i hope you will understand my post ^^ and thanks in advance for your help.
