Land Administration - UNECE, 1996 The processes of recording and disseminating information about the ownership, value and use of land and its associated resources. Land administration further includes restrictions and responsibilities related to rights, land value, land use and impact of development processes

Land Administration ISO 19152 Process of determining, recording and dissemination information about the relationship between people and land This International Standard deals with real rights and personal rights. Real rights are rights over or in respect of spatial units (e.g. ownership, or usufruct). Personal rights are rights that parties have (e.g. fishing rights, grazing rights, or use rights).

Land Administration Domain Model Components Parties (green) Rights (yellow) Spatial Units (blue) Surveying (pink) Geometry (violet) All this LADM modelling is done in the UML language. Here you see such a UML diagram with for every component a separate colour. Well, this is all inside the scope of LADM.

Fiscal Register A fiscal registry or database is supposed to record legal, physical, geometric, economic, and environmental characteristics of the property units, which are subject to immovable property valuation and taxation A Land Administration infrastructure is required to link fiscal registries with other public registries (e.g., cadastre, land registry, building and dwelling registries) The valuation discipline needs to be involved

Standardisation If the New Working Item Proposal is accepted the ISO TC 211 will develop the next LADM Edition in co-operation with its members and following the ISO procedures. On the valuation extension cooperation is needed: International Valuation Standards Council, Standards on Mass Appraisal of Real Property and International Property Measurement Standards There will be an extension of the scope of LADM with valuation.

Fiscal units – Tenure Units Different attributes Different spatial units Different Ids Different areas

Issues Spatial Units Taxation and Legal Security Mixed or Separated? Inclusion of Unregistered Lands in Valuation?

Thanks
