Visiting the Fondo de Tierras y Aguas of the Archivo Historico del Estado de Jalisco to verify document

I found a map in one of the tierras y aguas books that are available from familysearch.org, but unfortunately, whoever made the film didn't unfold the map to take pictures of it. it's really important for me to see that map unfolded, I have relatives in Guadalajara that might be able to go to the Fondo de Tierras y Aguas of the Archivo Histórico del Estado de Jalisco,and unfold the map and take pictures of it.

Is it possible to go there and see the actual documents?

Has anybody been there?
