Abstract:In this paper,the chatacteristics and approaches of all kind of interpolation of scattered data are sumarized and the approach of interpolation with the data that distance the inverse ration add the power is discussed in detail,and the authors had introduced the conceptions of effect region,effect points and data piece intersection.The Visaual C++ class based on the approach of Interpolation of 2D data sets and 3D data sets is developed and is embedded in the system of electronmagnetic data processing,thus it provides great conveninece for the visualization of large sets of scattered electronmanetic and gravity data.
Keywords:Interpolation approaches  Add the power of interpolation approaches  Programming realization
