The Open Geospatial Consortium (OGC) in August 2016 appproved the
Land and Infrastructure Conceptual Model Standard (LandInfra). 'The
scope of the Land and Infrastructure Conceptual Model is land and civil
engineering infrastructure facilities,' including road, railway,
survey, alignment, and land division.
'Land provides the environment upon which infrastructure facilities
exist.' Land division comprises administrative divisions (e.g.
jurisdictions) 'as well as interests in land (e.g., land parcels,
easements, and condominiums).' The standard also 'regards the surveying
needed to locate infrastructure facilities on the terrain in compliance
with interests in land.' (Cf. http://www.opengeospatial.org/standards/landinfra)
Candidate InfraGML encoding standards, Parts 0 - 6 incl were published
January 2017 (http://www.opengeospatial.org/pressroom/pressreleases/2520)
seeking public comment, and Part 7 was similarly published April 2017.
'Part 7 of InfraGML focuses on the land upon which infrastructure
facilities are built. Information about land parcel ownership,
administrative boundaries, and easements is critical to infrastructure
designers, as they need to understand what land is available for use
and if any additional land will need to be acquired before
construction. Traditional 2D cadastre is supported, as well as the
newer 3D land ownership exemplified by condominiums.' (http://www.opengeospatial.org/pressroom/pressreleases/2577)
ISO (the International Organization for Standardization) in 2012 issued
the Land Administration Domain Model (LADM) ISO 19152:2012. 'The LADM
is a conceptual model, ..' 'The purpose of the LADM is not to replace
existing systems, but rather to provide a formal language for
describing them, so that their similarities and differences can be
better understood. This is a descriptive standard, not a prescriptive
standard.' It is 'based on the conceptual framework of ‘Cadastre 2014’
of the International Federation of Surveyors (FIG) [14];' (https://www.iso.org/obp/ui/#iso:std:iso:19152:ed-1:v1:en). Motivation, standardisation, application and further development is described 2015 in an article of Land Use Policy by Peter van Oosterom and Christiaan Lemmen.
Relations between LandInfra and LADM
are described in Annex D.2
of the LandInfra conceptual model standard. The Summary reads: 'The
scope of LandInfra is land development and civil engineering
infrastructure facilities. The emphasis of LandInfra on infrastructure
and on surveying suggests minimizing as far as possible the
legal-administrative aspects of land development. This is achieved by
modelling what is needed to account for the surveying related
activities, including defining the legal entities, the boundary of
which are measured, as well as identification of the signing parties.
The scope of LADM reflect that mapping and recording of land parcels
often developed in service of the State, predominantly in terms of
taxation. Standards need cross-national English technical terms, a
challenge addressed by LADM. The narrower scope of LandInfra fits the
notion of ‘cadastral survey’, an Anglo-American concept which relates
the mapping of land parcels primarily to the securing of proprietary
interest in land.'
In September 2016, the OGC called for public participation in its newly-established Land Administration Domain Working Group (Land Admin DWG). Recent status of activities are available through Land Administration DWG Report to TC at 102nd OGC Technical Committee, March 21, 2017, Delft, The Netherlands.
