There is a new edition of this map coming out this year, so perhaps updates have been made to this site/depiction of coastline. I certainly know that the editing process involved a trawl of journals, grey lit, oasis, as well as consulting people who have extensive interests in the Roman period. One of the problems of the map is its scale, and I realised that several of the suggestions that I made won't necessarily show up at 1:500,000 or whatever it is, such as extensions to roads. Have you published your detailed research? Perhaps the local history/archaeology society journal would be interested.
