SplineCalc is multipurpose scientific calculator for implementation of various mathematical operations with maps (grids), data tables, lines, polygons (including multiply connected) and numbers. You can specify some surface analytically or load it from file, calculate first- and second-order partial derivatives, surface area and volume by contour integration with high precision. SplineCalc can be useful for hard scientist or Surfer users.
