Densifikasi InaCORS di Sumatera untuk Mendukung Kebijakan Satu Peta

Isnaini Annuriah Mundakir, Febrylian Fahmi Chabibi


At the beginning of its construction, the InaCORS network aimed to maintain the mapping reference system in Indonesia. As the needs of the community in the spatial field develop, InaCORS extended its function to the public service sector for accelerating and improving mapping accuracy in Indonesia. By the enactment of the Presidential regulation number 9 in 2016 on One Map Policy, the InaCORS function become stronger as an infrastructure so that maps and other geospatial information in Indonesia are at one geospatial reference, SRGI 2013. The Geospatial Information Agency supports the government's efforts to meet the needs of providing an efficient mapping reference frame through a fixed and continuous geodetic monitoring station known as the InaCORS station. In 2018, BIG prepared the InaCORS densification plan which would be implemented that year. From the 33 stations planned to be built in Sumatra in 2018, BIG was able to complete the construction of 33 stations, followed by densification optimization which could develop 17 additional stations. Therefore there are 50 new InaCORS stations being generated at CORS densification in 2018. From the analysis, the addition of these stations made the distance between CORS stations in Sumatra from the initial distance of 214 km to 107 km and RTK services in Sumatra have increased from single base correction to network correction.
