Descripción
The geoid is a closed surface representing the Earth's true shape, coinciding with mean sea level. It is used in geodesy to determine the orthometric heights of points. In this study, the e ect of di erent density models on the gravimetric geoid was investigated using the UNB Global Topographical Density Models at 1 arc-degree grid spacing and 30 arc-seconds grid spacing, as well as a constant density value of 2670 kg/m³. The computation of the geoid was based on the ITU_GGC16 global geopotential model. The SRTM model with 1 arcsecond resolution was used as the digital elevation model. Other terrestrial data were obtained from the Colorado region in the western United States.
