BoundsExtractor

Extracts a feature’s minimum and maximum coordinate values into attributes.

Jump to Configuration

Typical Uses

  • Determining a feature’s extents as attribute values instead of geometry.

How does it work?

The BoundsExtractor receives features with any type of geometry and individually extracts their minimum and maximum x, y, and z coordinate values, storing them as attributes.

Where coordinate values do not exist (such as z values on 2D geometry or non-spatial features) a value of zero (0) is assigned.

To exclude an attribute, leave the parameter blank and it will not be added to the output features.

Feature geometry is unchanged.

Examples

Usage Notes

  • Point cloud extents need to be recalculated after some operations. Consider using the PointCloudPropertyExtractor and its Calculate and Update Extents parameter instead.

  • To extract minimum and maximum values on attributes, use the StatisticsCalculator.

Creating Boxes and Rectangles

Creating rectangular geometry is a common task. These transformers do so in a variety of ways.

Editing Transformer Parameters

Transformer parameters can be set by directly entering values, using expressions, or referencing other elements in the workspace such as attribute values or user parameters. Various editors and context menus are available to assist. To see what is available, click beside the applicable parameter.

For more information, see Transformer Parameter Menu Options.
