| Name | Value Domain / Measurement | Description | Required / Default | Type |
|---|---|---|---|---|
| Area_Id | Area |
The points used to define the boundary polylines which themselves define an enclosed area. | Yes |
NUMBER(38) |
| Existence_Kind | REF_EXISTENCE_KIND NA |
A reference value that describes the state of existence in the lifecycle of the entity, for example, Planned, Predicted, Required, Simulated, and Actual. | Yes Actual |
VARCHAR2(64) |
| GUID | STRING128 NA |
Globally Unique IDentifier for an instance of a class. This GUID is not generated by the database, but is the GUID used by the application on first access of this object. Use of this property is optional and completely under the control of application developers. | No |
VARCHAR2(128) |
| I_Coordinate | double Dimensionless |
Representation of the X coordinate of the point in a system other than geographic. For example, a crossline number or CDP number. | No |
NUMBER |
| Id | ID No_Unit |
Unique identifier for this entity. | Yes |
NUMBER(38) |
| Insert_Date | DATE NA |
Date the entity was created in the repository | No |
DATE |
| Insert_User | STRING64 NA |
The name of the user responsible for the creation of this entity in the repository. | No |
VARCHAR2(64) |
| J_Coordinate | double Dimensionless |
Representation of the Y coordinate of the point in a system other than geographic. For example, an inline number. | No |
NUMBER |
| Line_Name | STRING255 NA |
Name of one of the polygon lines which bound the area, if they are uniquely named. | No |
VARCHAR2(255) |
| Line_Sequence_Number | int No_Unit |
Mandatory numeric ID of each of the polygon lines which bound the area. By convention the exterior bounding line is mentioned first. Interior lines which make holes in the area follow sequentially. Nested geometries of included and excluded areas are allowed, supporting islands containing lakes which contain smaller islands having ponds. However, these geometries can be defined in several ways. | Yes |
NUMBER(10) |
| Line_Topology | STRING255 NA |
Defines the topology between a polygon line and an area. A line may be defined to be an INNER or OUTER boundary of an area. The default value is OUTER. | No |
VARCHAR2(255) |
| Polygon_Sequence_Number | int No_Unit |
Mandatory numeric ID of each of the separate polygons which make up a polygon set (multipolygon). An example is a chain of islands. | Yes |
NUMBER(10) |
| Position_Id | Position |
A type of vertex that is located in, on, or above the Earth but is always locatable using a geo-referenced coordinate system. | No |
NUMBER(38) |
| Produced_By | STRING64 NA |
ID of the activity that was executing when the entity was created, for data created programmatically. | No |
VARCHAR2(64) |
| SDAT_Label | int No_Unit |
Label used by the security system for entitlements. SDAT is Secure Data Access Technology. | No |
NUMBER(10) |
| Update_Date | DATE NA |
Date of the most-recent modification to the entity. | No |
DATE |
| Update_User | STRING64 NA |
The name of the user responsible for the last modification to this entity. | No |
VARCHAR2(64) |
| Version | STRING255 NA |
The form or variant of the entity. | Yes 1 |
VARCHAR2(255) |
| Vertex_Sequence_Number | int No_Unit |
Mandatory numeric ID of each vertex of every polygon line which bounds the area, in sequential order. | Yes |
NUMBER(10) |
| Link | To Entity | Description | Implementation Technique | Required |
