Documentation | Other Specifications | Pipeline | Interpolation.PointCloudToGrid

Command `Interpolation.PointCloudToGrid`

generates a digital elevation model (grid layer) from a point cloud vector layer (e.g. LIDAR).

For more information please visit TGIS_PointCloudToGrid class.

Name | Required | Default value | Comment |
---|---|---|---|

Source | + | Source layer, point cloud such as LIDAR; must be 3D. | |

Destination | + | Destination grid layer; this layer must have the same CS as the source layer. | |

Field | the name of the numeric field which contains the values to be used for point cloud gridding; if empty, then the coordinate defined by the Coordinate property will be used. | ||

Assignment | Mean | Defines method of assigning point values within pixel. One of the following: Count, First, Last, Min, Max, Mean, Range, IDW, NearestNeighbor. | |

Coordinate | Z | Defines which coordinate is taken as value if the gridding is not based on an attribute field. One of the following: None, Z, M, ZM. | |

DefaultValue | 0.0 | If UseDefaultValue is true, then this value will be set for each grid cell for which the value cannot be computed. | |

DefaultValueFormula | DefaultFormula | Defines cell assignment method for NoData filling. One of the following: DefaultValue, Mean, IDW, NearestNeighbor, Triangulation. | |

Exponent | 2.0 | Exponent in the formula for weight calculation (applies if Assignment=IDW). | |

UseDefaultValue | False | If true, then each grid cell for which the value cannot be computed will be set to DefaultValue. | |

WindowSize | 3 | Defines window size for filling NoDataprocess; odd value required, even values will be rounded up. |
