PURPOSE Spatial interpolation programs using spherical geometry

+ variogram can be automatically fitted


+ All of the interpolation algorithms in Spherekit take account of the sphericity of the earth.
+ Inverse distance weighting
+ Triangulation
+ Ordinary point kriging
+ Multiquadratic
+ Thin plate spline

+ cross validation: error field, table of error summary statistics, histogram, and a scatterplot.
The overall error is computed either as the mean average error (MAE) or the root mean square error (RMSE).


+ Contouring and raster output
CODES Fortran and C codes available
