After two LADM workshops (Delft, March 2017 and Zagreb, April 2018) and three ISO TC211 meetings, where also LADM revision meetings took place (Copenhagen, May 2018, Wuhan, November 2018 and Maribor, June 2019) there is consensus growing towards the new scope of the standard. This new scope is described in this paper, and it is no exaggeration to state that there is a rather spectacular extension of Edition’s I scope. Below a first impression.

Some of the existing parts of the current version of LADM are being refined. The goal is that these refinements will add more semantics to LADM, but are also backwards compatible. A good example of such improvements are the Refined Survey Model (as part of the Surveying and Representation Subpackage) and more rigid representations of the various CodeList and the values they hold (adding more structure and using sematic technologies to define meaning of values).

The scope of LADM is extended with a valuation and fiscal perspective. This concerns a conceptual data model in a LADM Valuation Package that can be used to construct information systems for immovable property valuation and taxation and offer a data exchange option.

Spatial planning/zoning with legal implications is a further extension of the scope. This new LADM package implies integration of spatial planning and land administration environments and thus, re-use of zones from spatial planning as restrictions to land rights is possible. Both extensions have impact on the definition of land administration: land administration is the process of determining, recording and disseminating information about relationships between people and land - informal, customary and formal use and property rights - and about value and use of land.

What is more, the Global Land Indicator Initiative (GLII), seeks to derive a list of globally comparable harmonized land indicators, using existing monitoring mechanisms, and data collection methods as a foundation. Hence, the LADM is extended with attributes allowing monitoring, based on those indicators.
