GeodesyML for efficient positioning data delivery

ISO/TC211 standards used

ISO 19109 – Geographic information – Rules for application schema
ISO 19111 – Geographic information – Spatial referencing by coordinates
ISO 19115 – Geographic information - Metadata
ISO/TS 19139 – Geographic information – Metadata – XML schema implementation
ISO 19136 – Geographic information – Geography Markup Language (GML)
ISO 19142 – Geographic information – Web Feature Service interface

How the standards are used in our processes/projects

GeodesyML is designed as a GML (ISO 19136) application schema (ISO 19109) to help encoding geodetic data (as defined in ISO 19111) and metadata (as defined in 19115).

Positioning information, i.e. information about GNSS sites (and in the future also VLBI, DORIS and SLR) sites and measurements, reference frames, adjustments, quality and local ties are encoded in GeodesyML. 
Positioning information is delivered to the GNSS end-users (e.g. precise agriculture tractor driver, driverless car, or unmanned aerial vehicle) via WFS interface, such as ISO 19142 (WFS).

Benefits for the user

Delivering precise positioning information encoded in GeodesyML to the users provides lossless and interoperable information exchange of precisely defined information portion of interest. With positioning information encoded in GeodesyML, there is no need for intermediate format transformation tools, or specific surveying tools to ensure compatibility across organisations.
