Offsetter

Adds offsets to the feature's coordinates.

After you connect the transformer, you can enter parameter values as a number or pick the value of a feature attribute by picking Set to Attribute Value from the Parameter menu.

The feature will be shifted by the amounts specified.

Parameters

Mode

The mode in which to offset feature coordinates.

Cartesian Coordinate Parameters

X Offset, Y Offset, and Z Offset

A separate offset must be set for each of the X, Y, and Z axes. If the input feature is 2D and a Z offset is specified, the feature is converted to 3D, and the Z offset is applied from a starting Z value of zero. If the input feature is a raster, only X and Y offset values will cause coordinate location shifts. The Z offset will cause the values in the cells of the raster to be offset by the specified amount for each selected band.

Polar Coordinate Parameters

Distance

The distance to offset the feature.

Polar Angle

Angle in degrees CCW from the positive X-axis.

Spherical Coordinate Parameters

Distance

The distance to offset the feature.

Azimuth

Angle in degrees CW from the positive Y-axis.

Altitude

Angle in degrees from the XY plane. The angle between the XY plane and the positive Z-axis is 90 degrees.

Point Cloud

Component

Specifies a component to offset on point cloud features. Note that the x, y, and z components can be offset using the X Offset, Y Offset, and Z Offset parameters. This parameter is intended for non-spatial components (for example, intensity).

If the same component occurs multiple times in the table, each of the Offset values will be added to that component's value.

Offset

The offset that will be applied to the corresponding point cloud component.

Usage Notes

This transformer works with both raster and vector data.

This transformer supports raster band and palette selection. The RasterSelector can be used to modify selection.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
