4.1.4.4.5 Survey Elements Nesting

The ordered arrangement of survey annotations, such as point, lines, curves.

For set of survey elements where the order of items is not relevant (e.g., point clouds or collections of survey string lines), the Survey Elements Grouping template can be used.

The following diagram shows the generic classes and relationships used when applying this concept. In addition, concepts may have particular importance to common or standardised industry practices and scenarios. For these specific usage scenarios, the table below shows a recommended list of general usage patterns that users may adopt.
