| Popis: |
Medium resolution (1–3 arc-min) gravity anomaly grids do not reflect reality very accurately over terraced landforms, which in turn may affect the uncertainty of subsequent geoid modelling. This inaccuracy is due to many factors. The gravimetric datasets used in the gridding of gravity field models have a varying accuracy and coverage, especially in terraced and coastal areas. Further, the resolution of the terrain model used in the modelling of anomaly grids is usually too low to capture the complete gravimetric attraction of terraced landforms. |
