180764: <Value> has no vertical coordinate system defined. Using <value> as the vertical unit of measure for elevation comparison.

Description

A vertical coordinate system was not detected for one or more input layers. This can occur if there is no vertical coordinate system defined for the Levels layer, the Oriented Imagery layer, or both.

Solution

Do one of the following:

  • Define a vertical coordinate system for the input Levels or oriented imagery layers, and run the tool again.
  • Take no action. The unit of measure of the layer with a defined vertical coordinate system will be used for both layers. If neither layer has a defined vertical coordinate system, each layer will use the unit of measure from its own horizontal coordinate system.
