The module 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' module.
| | Name | Type | Identifier | Description | Constraints |
|---|
| Output | Grid (*) | Grid list (optional output) | 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 | ATTR_FIELD_GRID | The attribute field to grid. Field numbers start with 1, so elevation is attribute field 3. | Minimum: 3
Default: 1 |

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 | 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 []. | - |
