I was playing around with some stuff here and thought this would be a great feature but I could only come up with the following MySQL query which might be useful to others.
SELECT * FROM 'wp_eme_locations' WHERE location_latitude BETWEEN 51.5194 - 0.005
AND 51.5194 + 0.005 AND location_longitude BETWEEN -0.130049 - 0.005 AND -0.130049 + 0.005
If you think it might be a good feature, I'll see to what extent I can come up with something then I'll post again on here.
