Can Tremorsense replace sight?

This question it prompted by the recommendation of Ryan C. Thompson in relation to their answer to an earlier question of mine.

Does tremorsense, allow a monster to effectively "see" other creatures or does it only indicate location?

The first option would have tremorsense function the same as blindsight with the exception that it doesn’t work on flying creatures and can "see" behind walls and other obstacles.
The latter option would function similarly to locating an invisible creature where you know the creature’s location but it remains unseen.

Does Tremorsense allow Attacks of Opportunity while Blinded?
Is a character unseen by tremorsense while jumping?
