Mapping - distance

What Wildbook should this feature be in?
GiraffeSpotter

What would you like to see?
On the marked individual page, then the mapping section. It would be amazing if there could be a function added that you could measure the distance between the different sighting locations. (Like you can do in google maps)

How would this functionality help you?
This would give me fast information. Instead of downloading the coordinates and adding myself in a program.
