WHERE THE LADM AND LANDINFRA STANDARDS MEET: Interoperability Requires Sustainable Choices

The Land Administration Domain Model (LADM) is a conceptual standard
developed by ISO. LandInfra is a conceptional standard with an encoding in
GML (InfraGML) developed by the Open Geospatial Consortium (OGC). The
two standards have partly complementary but also partly overlapping
functionalities. Apart from InfraGML, there are several other implementation
standards. This article is an attempt to re-open the debate on the development
of standardization with future-proof choices in the domains of land surveying,
land administration and infrastructure.

[body]Land administration is by its very definition distributed among a host of
different units. Efficient administration calls for the interoperability of
information exchange, e.g. to implement the once-only principle of public
information sharing. Usable standards reduce data exchange costs.
