Yes - this is the official ISO/TC 211 OWL implementation, overseen by the ISO/TC 211 Group on Ontology Management, under chair Jean Brodeur (Canada). These ontologies follow the rules defined in ISO 19150-2, and are generated automatically - using automation tools in Sparx Enterprise Architect UML tool - from the UML originals in the so-called Harmonized Model repository hosted on behalf of TC 211 by JRC. 

The OWL implementations were being developed successively, since there was a need to do significant checking of each one after generation and in some cases non-visible pieces of the UML model (e.g. tagged values) required adjustment in order to get a conformant OWL. However, the work appears to have stalled about a year ago, incomplete with respect to the set of standards in the ISO 19100 series that actually have UML models. 

Linda, Clemens and Stuart Williams (Epimorphics) did a study of OWL implementations for INSPIRE a couple of years ago. Since INSPIRE is based on the OGC/ISO stack, this necessarily included an evaluation/critique of the ISO 19150-2 patterns and process. Linda can say more about this, but my impression was that there was significant scepticism about the brute-force rule-based transformation, since what came out could best be characterized as UML-in-OWL, therefore not very idiomatic OWL/RDF [1][2]. [OTOH, there are lots of ontologies out there that display as much or more baggage from earlier frameworks - look at all those based on BFO in the biomedical community for example!]  

[1]  My own successive OWL implementations of O&M addressed the same issue - the one presented at the 2013 Semantic Web conference largely followed ISO 19150-2, while om-lite started from scratch - see http://www.semantic-web-journal.net/content/ontology-observations-and-sampling-features-alignments-existing-models-0 for more details and references. 

[2] However, a conversation with Clemens at the time suggested that a bigger concern than particular OWL-style was a more fundamental 'why even do geospatial in OWL?', particularly at the level of detail represented in many of the UML models which are implementation-level with lots of typed attributes. I guess the SDW Working Group addressed this question in the original London workshop when the decision was made to set a work program that follows the RDF/semantic web path? (I wasn't there so not sure how rubust the discussion was on this point.)
