OpenStreetMap is the gold reference. I named all the trails that have names based on direct communication with the RAMBA leadership and looking at trailside signage.

I also would advise you to not add more trails or change anything unless you've gone there in person and surveyed things. There are a bunch of old spots that appear in the Strava heatmap and on older maps which go through active subsidance areas where the ground is literally collapsing. Much of it has been fenced off since the heatmaps were updated or other maps last produced. 

Unless you go there in person and survey things -- as I have done and continue to do for all of the RAMBA trails -- you'll produce inaccurate and unsafe maps.
