Integration of a Self-Developed GNSS Receiver with an Electronic Total Station for Urban Cadastral Surveying

Khai Cong Pham

Abstract: This study presents an integrated urban cadastral surveying approach that combines a self-developed low-cost GNSS RTK receiver with a Leica TS02 electronic total station. GNSS RTK is employed for establishing control points and surveying open-sky areas, whereas the total station is used to measure detailed points in environments with limited satellite visibility. Field experiments conducted in Can Tho City demonstrate that the integrated approach improves measurement reliability, spatial coverage, and operational efficiency while satisfying the positional accuracy required for cadastral surveying. The proposed system provides a practical and economical solution for urban cadastral mapping, particularly in developing countries where cost-effective high-precision surveying is essential.
