Resource information
The Study evaluated the locational suitability of established Continuously Operating Reference Stations (CORS) in Southwestern Nigeria and proposed optimum locations for additional CORS in the study area. These were with the view of determining the sufficiency of the existing CORS distribution for various applications in the study area. Secondary data were used for the study. The secondary data used were the shapefiles of the states and local governments as well as the positions of the CORS. The optimum locations of proposed additional CORS were based on 35km buffer distance and which is based on globally acceptable practices for Network Real-time Kinematics (NRTK) distance standard. The study proposed twenty-two new locations in Oyo, Lagos, Ogun, Ekiti and Ondo states for new CORS so as to achieve optimum distribution of CORS for efficient network operations and improved coverage within the region based on globally acceptable practices. The study concluded that the existing and proposed CORS in the study area achieved uniform distribution for accurate geospatial applications in the region.
