Description

The tool allows one to retrieve a grid from a virtual point cloud dataset by dragging a box (AOI) in a Map View. Optionally, the query can be constrained by providing an attribute field and a value range that must be met. A virtual point cloud dataset is a simple XML format with the file extension .spcvf, which can be created with the 'Create Virtual Point Cloud Dataset' tool.

Parameters

	Name	Type	Identifier	Description	Constraints
Output	Grid	grid list, output, optional	`GRID_OUT`	The output grid(s)	-
Options	Filename	file path	`FILENAME`	The full path and name of the .spcvf file	-
	Attribute Field to Grid	integer number	`ATTR_FIELD_GRID`	The attribute field to grid. Field numbers start with 1, so elevation is attribute field 3.	Minimum: 3 Default: 1
	Cellsize	floating point number	`CELL_SIZE`	Cellsize of the output grid [map units]	Minimum: 0.001000 Default: 1.000000
	Grid System Fit	choice	`GRID_SYSTEM_FIT`	Choose how to align the ouput grid system to the AOI	Available Choices: [0] nodes [1] cells Default: 1
	Aggregation	choice	`METHOD`	Choose how to aggregate the values	Available Choices: [0] lowest [1] highest Default: 1
	Constrain Query	boolean	`CONSTRAIN_QUERY`	Check this parameter to constrain the query by an attribute range.	Default: 0
	Attribute Field	integer number	`ATTR_FIELD`	The attribute field to use as constraint. Field numbers start with 1.	Minimum: 1 Default: 1
	Value Range	value range	`VALUE_RANGE`	Minimum and maximum of attribute range [].	-
