RoutingPoint feature
The ‘reasonForChange’ attribute is used across all features found within the OS MasterMap Sites Layer.
Defines the reason for a change made to a feature.
| Value | Description |
|---|---|
New | This is a new feature in the database. |
Modified | The feature has been edited by an operator. Used in the following cases: 1. The geometry of a topographic feature is changed following real-world change (applicable to point, line and text features only and not polygons). 2. The geometry of a non-topographic feature, for example, inferred link or BoundaryLine feature is changed. 3. A cartographic symbol feature is repositioned. 4. A CartographicText feature is repositioned. |
Reclassified | The descriptive attributes of a feature have changed. The feature code may have changed. |
Attributes | Applied to features that have had only attributes changed, except those covered by TextChange and Reclassified values. |
Position | Feature has changed geometry and/or position due to an improvement in its absolute accuracy; that is, its relationship to the National Grid (relevant for the positional accuracy improvement programme which is now complete). This type of feature change is not associated with real-world change. |
Software | Feature has been adjusted by an automatic software process. Includes geometric adjustment, cleaning, squaring, paralleling (text and lines) and reversing direction of digitising. |
