Building the Geodesic Network for the City of Gramsh through GNSS Surveys

This study presents the methodology and results of establishing a geodesic network for the urban area of Gramsh, Albania, utilizing Global Navigation Satellite System (GNSS) surveys. The development of an accurate geodetic framework is essential for various applications including urban planning, infrastructure development, and cadastral mapping. The research focuses on deploying GNSS receivers strategically across Gramsh to collect precise positioning data, which is subsequently processed using differential correction techniques to achieve centimeter-level accuracy. Ground control points are established throughout the city to facilitate georeferencing and validation of the network. Additionally, quality control measures such as redundancy checks and error analysis are implemented to ensure the reliability of the geodesic network. The resulting network provides a reliable spatial reference system for the city of Gramsh, enabling efficient and accurate geospatial data collection, analysis, and decision-making processes for urban development projects. This study demonstrates the effectiveness of GNSS surveys in establishing geodetic infrastructure in urban environments and highlights their significance in supporting sustainable urban growth and management.
