SplineCalc is multipurpose scientific calculator for
implementation of various mathematical operations with
maps (grids), data tables, lines, polygons and
numbers. You can use arithmetical and logical
operations with any above data types. It is possible
to specify some surface with usage analytical
expression or to load it from data file of various
popular formats. After you can calculate first- and
second-order partial derivatives, surface area and
volume by contour integration with highest precision.
Besides arithmetical and logical operations it is
possible to carry out union, inversion and subtraction
with multiply connected polygons. Any results can be
visualized. SplineCalc has the unlimited ability to
extend itself with usage your own functions and
variables. All expressions can be stored on and loaded
from disk as separate project. SplineCalc is powerful,
but it is very easy to use. Sixth samples are included
which show ample opportunities and high precision of
calculations. This software can be useful in
mathematics, physics, geology, geophysics, medicine,
ecology and biology. SplineCalc may be interested for
hard science students or as additional tool for
mapping software users, Surfer for example.
