adding annotation to a map

I'm trying to specify the location of an annotation for a map plot in terms of latitude and longitude instead of figure dimensions which is a number between 0 and 1. Is there a way to specify the annotation location in terms of lat and long on a map plot?

There is a File Exchange contribution https://www.mathworks.com/matlabcentral/fileexchange/32536-annotation-pinned-to-axes that pins annotations to axes instead of to figures, allowing you to specify the coordinates in axes coordinates. It probably does not work directly on map axes because the coordinate transformation for map axes is nonlinear, but perhaps you could make some adaptations.
