The fix.

I am running a server with:

MediaWiki 1.16.5
Maps 0.7.6.1
Semantic MediaWiki 1.5.6
Semantic Maps 0.7.6.1

Default language is Russian ($wgLanguageCode = "ru";). Name of type "Geographic coordinate" is NOT localized, it is still displayed in English language, regardless of the file extensions/SemanticMediaWiki/languages/SMW_LanguageRu.php:

protected $m_DatatypeLabels = array(
   ...
   '_geo' => 'Географическая координата', // name of the geocoord type
   ...

I found the cause of this bug. It is extensions/SemanticMaps/includes/SM_GeoCoordsValue.php file:

public static function initGeoCoordsType() {
    SMWDataValueFactory::registerDatatype( '_geo', __CLASS__, 'Geographic coordinate' );
    return true;
}

If I remove hardcoded type name:

public static function initGeoCoordsType() {
    SMWDataValueFactory::registerDatatype( '_geo', __CLASS__ );
    return true;
}

it will be properly localized depending on language. See attached patch.
