Spherekit is an integrated toolkit for spatial interpolation and comparison of spatial interpolation algorithms. It is UNIX-based and includes a complete graphical user interface (GUI). It uses Generic Mapping Tools (GMT) for display of interpolated fields. The package features several unique capabilities:

  • Large-scale interpolation --- Spherekit permits interpolation over continental or global scales because its computations are bas> spherical distances and orientations.
  • Smart interpolation --- Spherekit permits the user to incorporate knowledge or information about the processes that produced the spatial variations.
  • Error analysis --- The resulting error field can be displayed either at the data points or interpolated to a regular grid, to reduce any spatial biases. Error difference fields, comparing a pair of methods, can be easily displayed.
