Description

technical field [0001] The invention relates to an interpolation method, in particular to a space GIS interpolation method based on a spline function interpolation algorithm. Background technique [0002] Spatial interpolation is often used to convert the measurement data of discrete points into a continuous data surface for comparison with the distribution patterns of other spatial phenomena, and it includes two algorithms: spatial interpolation and extrapolation. Spatial interpolation Algorithm: Calculate the data of unknown points in the same area through the data of known points. Spatial extrapolation algorithm: use the data of known areas to calculate the data of other areas. In geographical statistics, the application of spatial interpolation methods has become the mainstream, but the spatial interpolation methods in the prior art are all based on computer software. , it is not able to quickly analyze the user-defined geographical area according to the real-time data ...
