Calculates the distance between a number of input vector lines and the elevation values of a reference DEM raster, and outputs a new DEM raster per input line.

The data contained in the resulting DEM consists of the 3D distance between the line being considered and the corresponding point on the reference DEM.

Usage Notes

  • 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.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
