+The case study is based on the input points of annual precipitation

Although positions of the points are given in three-dimensional space, the points are concentrated at the terrain and thus
interpolation above and below the terrain would become imprecise in deeper / higher areas of the dataset. That is the reason
to test just cross-section from interpolated 3D raster comparing it with cross-section from the RST result obtained using

<p>As the algorithm still needs to be optimized for large datasets, the original region was used with lower resolution
(hz: 5000 m, vert: 500 m). To test also original resolution, the points in smaller region (<b>Tab. 1</b>) were extracted.
