Official In depth Track Maps

I've been doing some searching around for official track maps with in depth description, names of each turn and best line or racing line. I was thinking that there should be a website of this for all the major Road Racing Tracks around the world. Does anyone know of a web site that provides any of what I have mentioned?

Thanks.

im pretty sure there is no website for it for free. you can buy it from the track i believe. its gonna cost you though. they wont give you the best lines, you have to figure that out one out.

I found this site it has over 300 track maps from old to new most of them have the names of each corner listed which is a plus.
