From points measures of temperature production of STATISTICAL SURFACE temperature map.
101 meteo station with record of temperature interpolated in order to produce a temperature map of my Study Area.
The interpolation method is IDW power value 2. The sample points are too uneven and few, the resulting surface will be affected by typical artifacts "Bull Eye".
Come vedrete, dato che i punti non sono distribuiti in maniera omogenea il risultato darà i cosidetti "bull eye", un artefatto tipico dell'IDW.....per cui in questo caso specifico la scelta del metodo IDW non è del tutto appropriata.
