Historical Duration of Base Triangulation Network of Turkey

Abstract

After establishing National Horizontal and Vertical Control Networks and Turkish National Fundamental GPS Network (TUTGA) for Turkey's geodetic infrastructure, governmental institutes that produce maps and map info like HGK (General Command of Mapping), TKGM (General Directorate of Land Registration and Cadastral of Turkey) and IKU (Istanbul Kultur University) established CORS-TR system in order to execute Turkey's defensive, developmental and scientific works with technological developments. CORS-TR, that has 146 permanent GPS stations across Turkey, enables users to calculate Real Time Kinematic positions with correction data. Therefore, in Turkey, mapping facilities are being done more rapidly, more economically and more easily.
