Heights of 22000+ GNSS stations on the surface from Nevada Geodetic Laboratory

This dataset is a point dataset of height of 22000+ GNSS around the world. This dataset is used to validate GDEMM2024 dataset from E. Sinem Ince, Oleh Abrykosov and Christoph Förste (2024), and have a potential to validate land digital elevation model or serve as ground control points (GCPs) for georeference and statellite images correction. 

Data process

Data are retrieved from the Nevada Geodetic Laboratory (NGL) (http://geodesy.unr.edu/index.php) using Web scraping package bs4 from Python. After parsing, the data is saved as geopackage (.gpkg) in a single file.
