What do the map symbols mean?

We represent observations on maps in two broad ways, to show large quantities of observations on the map at the same time or at coarse zoom levels, we use squares. 

When showing fine zoom levels, we use "markers," which look like teardrops for observations with public coordinates but display as circles  if the observation location is obscured from the public (see our Geoprivacy FAQ). All observations not marked as captive or as having location issues are mapped by default.

At very fine zoom levels, the grid cells are replaced by individual, clickable points. The colors of the points indicate the branch of the tree of life that the observation represents. A small white point in the center of the marker indicates that observation is Research Grade.
