I decided to take the plunge and try to link some of the city’s mentioned in the Hippolytus with those mentioned by Strabo and Ptolemy. The online text for Strabo, both Greek and English, can be found at archive.org the missing volumes can be found at the Perseus Project, and at Bill Thayer’s very useful website which has a digital transcription of most of Strabo. Ptolemy is another matter, his Geographia has only been translated into English once and it was done very poorly. The manuscripts also seem to be quite confused so the Greek editions that I have seen may be fairly useless (someone please correct me if I am wrong). So I think I am just going to stick with Strabo. I have found a good (latin) work of scholarship that discusses and translates the part of Hippolytus where he counts the stades around the Mediterranean. Hippolytus apparantly took this section from a nautical dictionary, part of which has been discovered. It can be found on page 427 of the pdf.
I have been at this for the better part of a year now and I am about ready to quit, hopefully I will finish soon.
