General Information

Name Project_Recommended_Xform
Entity Type Table
Description Specifies a project level list of appropriate datum transformations for use with recommended coordinate reference systems. These methods are for transforms between geographic coordinate systems. They are not used for re-projection from a single base geographic CRS to different projections with different projection parameters.

NameValue DomainProperty /

DescriptionRequired /
Default
Type
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)
From_CRS_Id Project_Recommended_CRS
The "From" geographic coordinate reference system involved in this recommended transformation method. There should only be one method for a given pair of "From" and "To" coordinate systems. Yes
NUMBER(38)
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)
Produced_By STRING64 NA
The name of application role that created the entity, 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)
To_CRS_Id Project_Recommended_CRS
The "To" geographic coordinate reference system involved in this recommended transformation method. There should only be one method for a given pair of "From" and "To" coordinate systems. Yes
NUMBER(38)
Transformation_Method R_Carto_Transform
The recommended datum transformation method used with this combination of "From" and "To" geographic coordinate systems. There should only be one method for a given pair of "From" and "To" coordinate systems. Yes
VARCHAR2(64)
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
