How to create a grid to do kriging interpolation that correspond to areas in a map having actual observations?

What is kriging a method of interpolation for geographical information systems?

Kriging is the method of interpolation deriving from regionalized variable theory. It depends on expressing spatial variation of the property in terms of the variogram, and it minimizes the prediction errors which are themselves estimated.

How do you interpolate maps by the kriging method in Qgis?

Quote from video: And i can define here the output pixel size i'll put it on one kilometer then i go to the interpolation tab. And there i can get the semi-variogram. Which it calculates from the points.

What is kriging interpolation techniques?

Kriging can be understood as a two-step process: first, the spatial covariance structure of the sampled points is determined by fitting a variogram; and second, weights derived from this covariance structure are used to interpolate values for unsampled points or blocks across the spatial field.
