I’ve figured it out with a bit of extra help. This is how you echo a link to Google maps and streetmaps using lat and long values.
<?php
$locations = em_get_locations_for( $post->ID );
if ( ! empty( $locations ) && is_array( $locations ) ) {
foreach ( $locations as $id => $location ) {
$optionValue = ( get_option( 'event_location_' . $location->term_taxonomy_id ) ? get_option( 'event_location_' . $location->term_taxonomy_id ) : get_option( 'event_location_' . $location->term_id ) );
$pb_google_map_limk = "https://www.google.com/maps/?q=" . $optionValue["google_map"]["latitude"] . "," . $optionValue["google_map"]["longitude"];
$pb_streetmap_limk = "http://streetmap.co.uk/loc/" . $optionValue["google_map"]["latitude"] . "+" . $optionValue["google_map"]["longitude"];
}
}
?>
<p><a href="<?php echo $pb_streetmap_limk ?>">View location on Streetmaps</a></p>
<p><a href="<?php echo $pb_google_map_limk ?>">View location on Google</a></p>
