hi, im sorry if this may have been asked before, but i already searched a lot and i can't seem find a solution.
i'm having trouble with some shapefiles from INEGI(Mexico).
they load fine and i can see them in arcmap, the problem is they dont fit well in any basemap like bing maps or openstreet.
Here is an example:

in some places they are like 5 blocks away from being correct.

any help or advice? thanks.
