Accuracy: the least obvious, most important data element

The four most important elements of an observation are a photo, a date, the coordinates (i.e., latitude and longitude), and a community-supported identification. When an observation has these four elements, it is considered “research grade”. However, there is a fifth element that is nearly as important as these other elements in determining the value of an observation to researchers, but it often gets overlooked. This fifth element is accuracy, which is the proximity of the measured latitude and longitude to the actual location where the observation was made. The accuracy can be determined by a GPS device or manually by the user using a mapping app, such as the iNaturalist map function.

The importance of having observations with high accuracy cannot be overstated. Only a small number of uses of iNaturalist observations can accept observations with low accuracy. For example, obtaining a species list for Griffith Park, Balboa Park, or one of the ten counties in ...more ↓
