Nowadays, the Land Administration Domain Model (LADM) is a significant issue for Cadastral Systems all over the World. Also, there are a lot of scientific activities have been carried out to establish a standard structure within the scope of land administration. In these studies have been limited to many aspects due to different features of Land Administration Systems in the World. To create a universal standard structure concerning the fundamental similarities of land administration systems, spatial data modelling studies were carried out in 2002. These studies were stated as a beginning named Core Cadastral Domain Model (CCDM), since 2006, it has been started to be made under the name of Land Administration Domain Model (LADM). This model was accepted in 2012 as a standard model in the field of land administration by the International Organization for Standardization (ISO). LADM has been an essential subject for Turkey since 2006 from the beginning until today.
In this study, Design and Development LADM for the Treasury Real Estate issue should be investigated and created. It is significant issues for Turkey Treasuries. An external model proposal is presented for the transactions of LADM regarding the properties of the Treasury. In order to determine the deficiency of this model, databases containing records related to spatial data and property rights were examined. Also, the deficiencies related to transactions on treasury properties were determined. For this model, National Property processing guidelines and regulations were examined, contract and specification samples were determined. External data classes were created for each transaction according to the contents of this document determined at the next stage. For modelling, Unified Modelling Language (UML) diagrams have been created by using the Enterprise Architect program. This external class is designed for acquisition, management and disposal of Treasury properties. The created external class is associated with the LADM's LA_Party, LA_RRR, LA_SpatialUnit and LA_BAUnit master classes. Herewith the standardization of the external data model is ensured. While the spatial information related to the immovables belonging to the Treasury is recorded in the National Property Automation Project (MEOP), the transactions on the properties will be recorded with the transformation of this standard into practice. In this way, it will be ensured that the necessary information for any past legal or financial audit process will be easily obtained from the database. Thus, the loss of time during the control will be reduced.
