The VLA used CAMA (Computer Assisted Mass Appraisal) techniques and proprietary spatial modelling software to assess capital values of domestic properties in Northern Ireland for rating purposes.
The automated CAMA and modelling software operate on data contained within the Agency’s core business database system.
The Valuation and Lands Agency has spent a total of £1.40 million in respect of the automated valuation model and associated computer database and training.
Geocode data do not contain data on proximity to geographic features or facilities.
Variography techniques were not used by VLA in the construction of valuation models. While the Spatialest software is capable of applying variography techniques the VLA modellers did not use the facility.
