The membership of the Open Geospatial Consortium (OGC®) seeks public comment on the candidate OGC LandInfra Conceptual Model.

This document, the first public draft of the OGC's proposed UML conceptual model for land parcels and the built environment, communicates the proposed intent and content of a new candidate OGC standard to be called the OGC InfraGML Encoding Standard. The UML conceptual model establishes a single set of consistent concepts that could be implemented in GML (as InfraGML) or in other encoding mechanisms.

After reviewing the existing LandXML format, the OGC Land and Infrastructure Domain Working Group (LandInfraDWG) decided that a fresh start standard was warranted. The new standard would have a use case driven subset of LandXML functionality, but it would be consistent with the OGC standards baseline, implemented with the OGC Geography Markup Language (GML), and supported by a Unified Model Language (UML) conceptual model. Called InfraGML, this new standard would: be supported by a recognized Standards Developing Organization, OGC align with existing OGC (and TC211 and SQL/MM) standards, including the OGC Modular Specification benefit from functionality already supported by GML, including features, geometry, coordinate reference systems, linear referencing, and surface modeling (TIN) initially focus on alignments/roads, survey, and land parcels, the subject areas for which there are identified needs and committed resources for development using modular extensions, be able to expand into other areas (e.g., "wet" infrastructure pipe networks) as resources become available be use-case driven be based on a UML conceptual model developed prior to any encoding, such as GML have more up-to-date functionality be synchronized with the concurrent efforts by buildingSMART International in their development of Infrastructure-based Industry Foundation Classes (IFCs), and be more easily integrated with TransXML and OGC CityGML.

The document for the candidate OGC LandInfra Conceptual Model are available for review and comment below.  Comments are due by 22 February, 2015.
