Description:
This local geoid model covers the Kanpur Nagar district and part of the Unnao district and the Kanpur Dehat district, corresponding to an area of about 25 km (East-West) × 28 km (North-South). The model was computed by interpolating GNSS/levelling values at 35 Ground Control Points (GCPs). Kriging interpolation method was used to obtain a geoid undulation model above the WGS84 ellipsoid on a grid size of 10 × 10 arc-second. The accuracy was evaluated by dividing the GCPs into five groups and performing a five-fold cross-validation (namely taking four groups as training data-set and the remaining one as testing data-set). This leads to an estimated accuracy of 4.4 cm.
