## IDW

**Syntax**

IDW(string InPointsPath, int InValueFieldIndex, string OutGridPath, double CellSize, double Power)

**Summary**

Inverse Distance Weighting Interpolation

**Parameters**

InPointsPath |
Input point shapefile path to interpolate |

InValueFieldIndex |
Input field index where interpolation value is stored |

OutGridPath |
Output grid path where interpolation is stored |

CellSize |
Cell Size for output grid. Default lower of points extent height or width divided by 250 |

Power |
Power variable for IDW algorithm. < 1 will give sharp changes. >1 will give smoother. Default 2. |
