Lost Map Clues: 2008

Actually, there's always some kind of interpretation in the things we see and there are only very few real facts (or pretty obvious ones) in Lost. So here's the list of everything I would qualify as a fact or better: "very valuable hint". In addition, I've posted the list of maps/screens we have seen with my subjective rating for the reliability of their source and accuracy.

Maps/screens

Map	Rating	Comment
Danielle's island map	80%	we don't know if the magnetic anomaly is taken into account but Sayid has used this map up to season 3
Danielle's side view map	80%	contains weird equations and notations, scale doesn't seem to be realistic
Blastdoor map	80%	no north arrow, cryptic notes and many assumptions on it ("alleged position of ...")
Henry Gale's map	90%	no north arrow but they managed to find HG's balloon with
Season 3 opener panoramic shot	99%	it's CGI and therefore exactly what TPTB wanted us to show
Hydra island view	99%	same as above
Cable map	95%	It should be very precise but we don't know if the magnetic anomaly is taken into account
Road map	90%	many topographical hints about the surroundings of the Swan but bad screenshot quality
Looking Glass map	90%	no north arrow
Ben's map	99%	Ben uses it for planning treks
Kate's map	95%	Kate might have marked only striking landmarks
Dan's map	90%	A lot of "unknown" captions indicating that it might not be accurate
Ben's Temple map	99%	Ben wants to save Alex's life
Horace's map	99%	Locke, Ben and Hurley use it to get to Jacob's cabin
