First Edition of the Land Administration Domain Model (LADM) has three packages related to: Parties (people and organisations); Basic Administrative Units, Rights, Responsibilities, and Restrictions (of ownership rights); spatial units (parcels, and the legal space of buildings and utility networks) with a sub package for Surveying and Representation (geometry and topology). The latter sub-package provides the functionality to manage observations and cadastral surveys measurements.
Contents of LADM implementations are based on authentic source documents, including the names of the persons having a role (responsibility) in the process of the initial data acquisition and/or in the maintenance process. This concerns legal/administrative data and spatial data based on field surveys and observations – where responsible professionals can be conveyors, registrars, surveyors, grassroot surveyors, citizens themselves (participatory surveying) and paralegals.
Some of the existing parts of Edition I of the LADM are proposed to be refined in the context of development of Edition II of the standard. This will allow for the inclusion of better structured meta data – also in support of participatory approaches in cadastral surveying. Richer semantics may require more rigid representations of the various Code Lists and the values they contain (adding more structure and using sematic technologies to define meaning of values).
An extended survey and legal models are proposed and presented in this paper. This implies adjustments from field observations to the spatial database and the generation of quality labels.
