fed_permit_sys_legal_srvy_area.reference_latitude
The reference latitude, usually the south bounding latitude. reference_latitude_1_u: Defines the unit of measure. Defines a foreign key to table r_unit_of_measure. reference_latitude_o_s: Defines the origin of the coordinate value(s). Defines a foreign key to table spatial_object. reference_latitude_cs_s: Defines the coordinate system of the coordinate value(s). Defines a foreign key to table coordinate_system.
fed_permit_sys_legal_srvy_area.reference_longitude
The reference longitude, usually the east bounding longitude. reference_longitude_1_u: Defines the unit of measure. Defines a foreign key to table r_unit_of_measure. reference_longitude_o_s: Defines the origin of the coordinate value(s). Defines a foreign key to table spatial_object. reference_longitude_cs_s: Defines the coordinate system of the coordinate value(s). Defines a foreign key to table coordinate_system.
source (O: CHAR VARYING(80))
e_and_p_data.source
The provider of this instance, which is usually a data provider for imported/purchased data. If this instance is provided by POSC, then this attribute must be "POSC".
source_content (O: CHAR VARYING(80))
earth_feature.source_content
This is the original source of the data. This is the person, company or application that defined or specified the data (content) for this instance and is considered to be responslble for it. For example, POSC, EPSG, API, ISO, etc. This may be the same as or different from the provider of the instance (e.g., POSC).
source_reference (O: CHAR VARYING(2000))
earth_feature.source_reference
The reference used by source to provide the standard instance, such as Petroleum Industry Data Dictionary (PIDD), Websters Ninth New Collegiate Dictionary, etc.
status (O: CHAR VARYING(11))
earth_feature.status
The status of this instance in the version of Epicentre running in a data store. This is an enumerated datatype for which the following are the possible values: current, provisional, deprecated. Current - use without restriction. Provisional - use with caution, this value is for comment and may not appear in future releases of Epicentre. Deprecated - avoid use if possible, it is planned to remove this value in the next major release of Epicentre.
surface_only (O: CHAR(1))
earth_feature.surface_only
When set to TRUE, this earth_feature represents only the surface of the Earth and does not extend into the subsurface.
earth_feature.unique_within
This is another earth feature within which this earth feature is uniquely identified. unique_within_s: Implements a foreign key to a row in one of the tables projected from entity earth_feature depending on the value of the next column (See below). unique_within_t: Defines the name of the referenced table. Possible values are defined in @earth_feature.
version_s (FSK, O: CHAR VARYING(19))
earth_feature.version
This describes the version of this instance as defined by the provider.
Defines a foreign key to table r_version.
