During this spell’s duration, you can touch the sign of a creature’s passage that you have identified using the Survival skill to make the other steps in the creature’s path perfectly clear to you, no matter how minute.
Obviously "a sign of a creature's passage" refers to footprints, blood left behind, disturbed foliage, probably even a creature's scent, assuming you have the Scent ability, etc. My question is if another creature makes their Survival check and points out a set of tracks for me, can I use this spell from that point without the need for my own successful Survival check?
Does pointing out a sign of a creature's passage to another PC count as the other PC making their Survival check to spot said signs? Pointing out a hidden object you've spotted with Perception to another PC would count as that other PC making a successful Perception check to also spot the hidden object, or so I would assume.
I mean, technically you've still identified it using the Survival skill. You simply used somebody else's roll. : )
But I'm with merpius on this one, though I'd treat it as a lowered DC so that it might go below the "training required" threshold. Same with the Perception thing. You ever have someone point at some hidden detail and tell you it's there but still manage to not see what the heck they're talking about? Sometimes help just isn't enough.
