Looking for info from the Texaco GP Of Houston 1998 -2001

My dad and I used to go back when I was a wee lad. Im currently working on a project and need things like distance of straights, angle of the turn, racing line, buildings surrounding the track, grandstands, ect… The area has changed quite a bit and its hard to gather any info from the VODs of the few races there.

Edit: Id like to add if you lay the transparent PNG of the track over the area in google maps, certain parts do line up. Granted not everything lines up 100% and there has been extensive construction in that are.
