NAME

Natgrid is a package for gridding 2D randomly-spaced data using a natural neighbor algorithm. Single precison and double precision interfaces exist in both Fortran and C.

 NNGETI        retrieve values for INTEGER parameters.

 NNSETR        set REAL parameter values.

 NNGETR        retrieve values for REAL parameters.

 NNSETC        set CHARACTER valued parameters.

 NNGETC        retrieve values for CHARACTER parameters.

 NNGETSLOPES   get slope values, if calculated.

 NNGETASPECTS -  get aspect values, if calculated.

 NNPNTINITS    initiate single point mode.

 NNPNTS        interpolate at a single point.

 NNPNTEND      terminate single point mode.
