OGC Seeks Public Comment on Draft Charter for New Portrayal Domain Working Group - 18/02/2019


Portrayal concerns the way that information, in this case geospatial data, is presented to humans. Cartography, one form of map portrayal, is one of the oldest human graphical portrayal skills. OGC is now seeking public comment on its draft charter for the Portrayal Domain Working Group (DWG), which is being established to address a gap in the OGC standards baseline with regards to the portrayal of geospatial data, including the standardization of portrayal rules, registry data, styles and encoding formats.

Traditionally, conveying spatial information involved the use of maps. However, as the types and complexity of geospatial information has changed in-step with technological advances, so have the requirements for the portrayal of this information. For example, it is now common for geospatial data to be portrayed (visualized) in areas such as 3D, augmented reality, and gaming & simulation. Additionally, multi-dimensional portrayal is rapidly expanding as advances in information technology and computer graphics make more visualization alternatives available. 

Broader approach within a unified framework

Many of these technology advances are currently being considered across several OGC Domain and Standards Working Groups. However, they often consider only a portion of the portrayal challenge or address a portrayal solution tailored to a specific issue and not a broader approach within a unified framework. 

OGC will benefit from a coherent organization to ensure that common and consistent frameworks and approaches are applied to portrayal issues. 

The Portrayal Domain Working Group, therefore, will bring together a community to define a common portrayal framework, provide direction to portrayal Standards Working Groups, and provide guidance to other Domain Working Groups on portrayal concerns. 

OGC membership has registered a concern that without a portrayal framework with updated consensus standards and Best Practices, divergence will continue in the community and interoperability will be inhibited. External to OGC, multiple communities of interest such as the Defence Geospatial Information Working Group (DGIWG), the U.S. National System for Geospatial-Intelligence (NSG), the American, British, Canadian, Australian, and New Zealand (ABCANZ) Armies program, the meteorological and oceanographic community, and the International Hydrographic Organization (IHO) have advocated for increased portrayal capabilities supported by OGC standards. 

The Portrayal Domain Working Group draft charter is available for review and comment on the OGC Portal. Comments are due by 7 March 2019 and should be submitted via the method outlined on the Portrayal Domain Working Group draft charter request page.
