surfit For Linux

Surfit is a program which enables to calculate regular grid from various data (scattered points, 2D and 3D contours, surfaces, etc) in different ways (interpolation, approximation, inequalities, etc). Surfit implements the original gridding method.

Here are some key features of "surfit":

� Allows to build your own gridding algorithm by defining a set of so called "gridding rules". � Allows to build "gridding rules" from: � scattered points (surface should interpolate or approximate points); � curves (surface should interpolate or approximate curve with constant value or with values taken from other surface); � areas (surface should interpolate or approximate area with constant value or with values taken from other surface); � contours (surface should interpolate or approximate contour); � surfaces (surface should interpolate or approximate other surface); � inequalities (based on points, curves, areas, ... ); � linear conditions (mean or weighted mean values for whole surface, or in some area). � Can deal with HUGE data sets. � Quality of resulting surface can be comparable with a surface created by Kriging or Minimum curvature method. � Supports various data formats.

What's New in This Release:

� 10 new "gridding rules". � New module libsurfit_io - implements import/export procedures for various data of various formats. � New module surfit4saga - plugin for SAGA-GIS, that allows to call surfit gridding method from SAGA. � New version of tool for creating scripts and results visualization: funner-2.1b. � Minor bugfixes.
