Regularised computation of 3D coordinates and orthometric heights for northern Cyprus: new network computations for northern Cyprus

This study covers the restoration of 124,910 parcels between 2013 and 2016 within the scope of the digital cadastre renovation work of northern Cyprus. The renovation work was commissioned by the Republic of Turkey Land Registry and Cadastre General Directorate via the tender process and turned over to the Turkish Republic of Northern Cyprus (TRNC). The geodetic infrastructure of the project consisted of 37 C2 and 68 C3 geodetic control points. 3D location calculations of the C2 and C3 networks were obtained based on the Continuously Operating Reference Stations Turkey (CORS-TR) System (in reference epoch 2005.00 and datum ITRF96) and interpolation was determined via annual velocity vectors. In order to include the C2 and C3 networks in the TRNC Vertical Control Network, nine compatible vertical control points were included in the calculations. In this study, an orthometric elevation model specific to northern Cyprus was formed by using the 3D position information obtained via the Global Navigation Satellite System and the Cyprus geoid data.
