A tool for two-steps interpolation has been released in our scripts and tutorials section.
The tool presented is an interpolation tool developed to increase the performance of traditional griddata function in certain situations.
It computes the relation between the two sets of points locations (source and destination) once and allows to use this information several times, in case it is needed. It is specially useful when different variables (surfaces) have to be interpolated between two grids, reducing the computational cost.
