| Name | Land_Description |
|---|---|
| Entity Type | Table |
| Description | Analogous to PPDM 3.7s SPATIAL_DESCRIPTION. The surface and sub-surface description of land. The surface description may be stated in terms of a legal survey system, metes and bounds, text, or polygons. The mineral zone description describes the minerals (substances) and subsurface definition (zones/formations). |

| Name | Value Domain | Property / Storage Unit | Description | Required / Default | Type |
|---|---|---|---|---|---|
| Areal_Extent | double | Area m2 |
The areal extent of the surface area of the land. | No |
NUMBER |
| Areal_Extent_OUOM | R_Unit |
|
The identifier of the original unit of measure (OUOM) (for example, acre or hectare) for the areal extent. | No |
VARCHAR2(64) |
| Bounding_Area_Id | Area |
|
If the surface boundaries of a land description are described in terms of an area, this is the identifier for that area. | No |
NUMBER(38) |
| Current_Status | CODE | NA |
The current status of a land agreement | No |
VARCHAR2(64) |
| End_Date | DATE | NA |
The date on which this land description was no longer effective. | No |
DATE |
| 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. USAGE NOTES: There are two cases: 1) GUID is not populated or used; and 2) it is populated with a value that is globally unique. If the GUID is populated there are two means of doing so for a given project: 2a) Seabed automatically generates and populates the GUID when an instance is created (valid only on Oracle based systems); and 2b) the GUID is generated and populated by an application (other than Seabed) on instance creation. Whether Seabed automatically generates GUIDs for a project is determined by the Auto_GUID flag in SDS_Account. Note that techniques 2a and 2b can coexist in the same project. When GUIDs are automatically generated an application can override the automatically generated GUID with its own GUID by simply supplying the GUID value. Applications that generate their own GUIDs and populate the GUID column will function correctly on projects which have automatic GUID generation turned on. | No |
VARCHAR2(128) |
| 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) |
| Land_Description_Type | R_Land_Description |
|
The type of land description. May be for a land agreement, a restriction, an obligation, a block, etc. | No |
VARCHAR2(64) |
| Name | ENTITY_NAME | NA |
The name given to any object or data item, e.g. name of Well, name of Field, etc. | No |
VARCHAR2(255) |
| Nominal_Position_Id | Position |
|
The nominal position of the item. Considering the item has a spatial extent - meaning it is not a single point and could span more than one county or section or whatever - the Position created as the target of this link is just a representative location. If a more complete answer is needed a GIS query can intersect the polygon marking the outer boundary of this item with the desired item. For example, the Viking Graben (a basin) is mostly in Norway but extends over the border into the UK. Its Nominal_Position could be said to be Norway. If someone wondered exactly which countries it touched they would use GIS functionality to intersect the basin outline with a map layer containing the international boundaries to see which countries actually contain some portion of the basin. | No |
NUMBER(38) |
| Original_Source | STRING64 | NA |
The name of the person, Organization or project source that originally provided this entity, e.g. "IHS-EnergyData" or "FinderUpper Stratton Deeper Pool 15" | No |

Any type of remarks added to an entity instance. | No |
VARCHAR2(2000) |

Label used by the security system for entitlements. SDAT is Secure Data Access Technology. | No |
NUMBER(10) |
| Source | STRING64 | NA |
Name of the person or organization responsible for this entitys E and P content and quality. Not the data technologist or IT expert creating the entity, for which see IT_Object.Insert_User and Update_User. | No |
