					              UK Hydrographic Office in Move Towards GML

The UKHO has taken the first step in adopting Geography Markup Language
(GML) in hydrographic data by developing a GML schema for S57 ENC data.
The scheme will aid the interoperability of data produced by different vendors
and facilitate the representation of S57 ENC data in GML.

The initial version of the GML schema has been developed by the UKHO in
association with Galdos Systems Inc ( The schema has
been made freely available and the UKHO is inviting feedback from members
of the wider Geographic Information (GI) community on the schema’s S57
interpretation and modelling.

GML is fast becoming the standard in the transfer and representation of
Geospatial Information with many authoritative geospatial data suppliers
already using GML or working towards its adoption. GML fully conforms to
standards co-developed by the ISO Technical Committee 211 and the Open
GIS Consortium Inc (OGC), an international organisation that is leading the
development of standards for geospatial and location based services.

John Pepper UKHO’s Head of Commercial Development says: “The GML
schema is a significant starting point in the UKHO’s adoption of GML. We
have made the schema freely available and invite people to view it and
provide us with their feedback so we can effectively manage its future

The GML schema can be found on the UKHO website
under the business to business section. Feedback is welcomed by the UKHO
and can be submitted via a downloadable feedback form.
