In geographic information systems, interpolation of surfaces by various methods is often used. Topics in this area are relevant today and promising for further study and practical research in the field of geoinformation using GIS technologies. The purpose of interpolation in GIS is to fill in the gaps between known measurement points and thus simulate a continuous distribution of a property (attribute). Interpolation is based on the assumption that spatially distributed objects are correlated in space, that is, adjacent objects have similar characteristics. Spatial interpolation of point data is based on the choice of analytical surface model.
