Hey, While this won't help you for data from the SPARQL endpoint, the Geo library can be of use when working with coordinates from Wikidata/Wikibase.
https://github.com/DataValues/Geo/ This library is used by Wikibase and can thus both parse the coordinates coming from the wiki software and format coordinates to a format the wiki software supports. This library is also used by Semantic MediaWiki [0] and the Maps extension [1], so aids interoperability there as well.
