Description:
The Uruguayan geoid model, called SGM2007, was calculated by the Military Geographic Service (SGM) in 2007. The extent is from 29° S to 36° S in latitude and 52° W to 60° W in longitude, however the model is valid in the Uruguayan territory only. The grid resolution is 1´ x 1´. The geodetic reference system is WGS84. SGM2007 was computed by adapting the UruGeoide2007 gravimetric model by a bias and a tilt to the national vertical system, Cabildo 1948. This was performed by fitting 50 GNSS/levelling observations with an accuracy of 2 cm. The SGM2007 model was the official Uruguayan geoid model for height conversion until the introduction of the IGM110 model.
