Description:
ILUM 1.2 is a geoid model for Israel computed by interpolating GPS/levelling data. In particular a Kriging interpolation method
was applied. Whereas the ILUM 1.1 model improves ILUM 1.0 especially in the the southern area close to Eilat, the ILUM 1.2 model
is an update of ILUM 1.1 in the Negev area and in the Beit-Shean valley, where GPS/levelling measurements were not conducted previously.
Altogether the ILUM 1.2 undulation surface was constructed on the basis of 849 measurements. The model accuracy is evaluated by comparing
it with 7 pairs of benchmarks, located from the North of the country to the South. The rms of the discrepancies is equal to 5.4 cm.
