Hmm, I'm not sure I understand fully what you are asking, but what the hell, I'm going to try and help anyway.
I think you are asking, "By looking at the map, can I tell where the quest started, as some of the quest require me to return to that quest point to finish the quest?" If that is what you are asking, then the answer is "Kind of" If you look at the cloth map, the quest site will change colors if it is a part of an active quest, but it won't tell you which quest it is a part of exactly.
