Trips enable the collection of presence-absence data by adding context to your observations

Why Presence-absence data include information about sampling effort which is useful for scientific analyses like distribution modeling (raw iNaturalist observations are 'presence-only' data).

How A trip adds context to your observations by recording:

• What you searched for (target list)
• Where you searched (search area)
• When you searched (search interval)

Species on your target list that you were able to observe within the search area and interval are interpreted as presences. While species on your target list that you were unable to observe are interpreted as absences.
