You can only zoom in so far on it, and it's displayed pretty much with the cardinal directions properly oriented, (well, mebbe 95 to 275 or so degrees) so's the PAB flightline is almost East-West... it's clear, but the area just to the South is very much overgrown.
The juncture of QL 19 and QL 14 (South to Camp Enari) is clear, if I recall.
mebbe not...
