Right now I'm in a project to recreate parts of the city of rome from 0 AC to 180 AC; while most of the research, like architecture and society is widely available, I still have problem finding a well sourced map of rome. I found plenty of unsourced maps, most of which agree too some degree on the general outshape of the city, but are there any detailed and well sourced maps of the city of Rome from somewhere in this period?
I'm not certain what you mean by "sourced" vs. "unsourced" precisely -- any modern attempt to recreate Rome's cityscape, whether during the mid-Republic or under the Antonines, is going to include some topographical features that are well-supported by various historical and archaeological sources and some that are not. The Forma Urbis is a good place to start; Lanciani utilized it in conjunction with the excavations conducted during the late 19th century to form his own "Forma Urbis Romae." This, along with Platner and Ashby's topographical dictionary, were the go-to sources for much of the 20th century. In the last 30 years there have been a number of efforts to produce maps and topographical dictionaries that recreate the urban landscape more accurately. If you want the most up-to-date interpretations, you might want to check out [Richardson 1992] (http://books.google.co.uk/books/about/A_New_Topographical_Dictionary_of_Ancien.html?id=K_qjo30tjHAC&redir_esc=y), the magisterial Lexicon Topographicum Urbis Romae, and the Mapping Augustan Rome project. Hope that helps.
