4.2.5.1 Data Model

The tool error model (ToolErrorModel) (Figure 4.2.5.1-1) data object is used to define a surveying tool error model. The tool error term set (ToolErrorTermSet) (Figure 4.2.5.1-2) data object is used to define a set of surveying tool error terms that may be used in a tool error model.

Important points:

• The tool error model and term set are each top-level objects.
• A trajectory references a related tool error model.
• The tool error term set references a tool error model.
