Error number | Error message |
---|---|

0 | No error. |

1 | Invalid number of input points (must be greater than 3). |

2 | Invalid dimension for latitudes in the output grid. |

3 | Invalid dimension for longitudes in the output grid. |

4 | First three nodes of input array are collinear. |

5 | Extrapolation failed due to the uniform grid extending too far beyond the triangulation boundary. |

6 | Internal algorithm error - please report this. |

7 | Vertex of a triangle containing an interpolation point is outside its valid range. |

8 | The angular distance between an interpolated point and the nearest point of the triangulation is at least 90 degrees. |

9 | Not enough input points to calculate a gradient. |

10 | Insufficient space for the triangulation (must be >= number of boundary nodes minus 2). |

11 | Degenerate triangle (two vertices lie on same geodesic). |

-L | Coordinates L and M coincide for some M > L >= 1 (coordinate numbering starting at 1). |
