Geography Markup Language

The OpenGIS® Geography Markup Language Encoding Standard (GML) The Geography Markup Language (GML) is an XML grammar for expressing geographical features. GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet. As with most XML based grammars, there are two parts to the grammar – the schema that describes the document and the instance document that contains the actual data. A GML document is described using a GML Schema. This allows users and developers to describe generic geographic data sets that contain poi...

GeoMobile and Internet of Things

Background

Access to the Internet will predominantly be from mobile devices including smart phones and machine-to-machine interactions.  Most information exchanged in mobile internet will include spatial components.  

In support of OGC members and society, this OGC Interoperability Program initiative aims to help develop the consensus standards infrastructure necessary to achieve the full societal, economic and scientific benefits of location information in mobile applications worldwide.

GeoSPARQL - A Geographic Query Language for RDF Data

The OGC GeoSPARQL standard supports representing and querying geospatial data on the Semantic Web. GeoSPARQL defines a vocabulary for representing geospatial data in RDF, and it defines an extension to the SPARQL query language for processing geospatial data. In addition, GeoSPARQL is designed to accommodate systems based on qualitative spatial reasoning and systems based on quantitative spatial computations.

Geospatial Fusion Testbed

Testbed. The 2000 Geospatial Fusion Testbed addressed standard ways of "fusing" disparate kinds of data into one spatial framework. Such data include text with embedded place names as well as video, sound, and photos whose metadata refer to "place." Through Geospatial Fusion, they can be geo-indexed, integrated with other spatial data, and shared across the Internet. The Testbed mainly addressed text, but OGC's specifications will accommodate the other kinds of data.
