A large map size is advantageous with a large number locations, but users may not notice the location list below a large map. I suggest adding a named anchor at the beginning of the location list to enable linking to the list from above the map.
That can be accomplished by changing Line 594 of eme_locations.php from:
$result .= "<ol id='eme_locations_list'></ol>";
To:
$result .= "<a name='eme_location_list_top' id='eme_location_list_top'></a><ol id='eme_locations_list'></ol>";
Users can then optionally put something like this above maps to link to the location list below:
<a href="#eme_location_list_top">View List</a>
