| 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. |

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 |
