Decompiling maps to show locations of loots

[al-kinda]

Hey i was just playing Celle, and there is NO god damn accurate map online.

im wondering if there was a way to take that map, and plot out the locations of buildings/military/industrial like dayZdb, would this be possible?

Thanks for your time.

You don't "decompile" a map. You could load up the map and have the grid and ground features there. However, the advanced maps that are on sites like DayZDB are done by taking a series of screenshots of the map at different zoomed levels and then MANUALLY placing the locations. Simply Google on how to do this and you'll find your answer.
