Defines vertex behavior for a node in a seismic acquisition array. This allows, for example, the semantics of a particular seismic station to be used as the origin for a coordinate system. This entity is not intended to substitute for the arrays in Seismic Geometry Set. If the detailed acquisition arrays are not defined (i.e., a uid does not exist) then the name which would otherwise be assigned to the node can be used as the identifier of the node and the Pty Location 2D may specify the location of the node.

seismic_acq_vrtx_s (PK, M: CHAR VARYING(19))

Surrogate key of the table.


r_seismic_acq_vrtx (FNK, M: CHAR VARYING(40))

seismic_acquisition_vertex.ref_seismic_acquisition_vertex
Defines the type of array that the node uid represents. This values implis a particular attribute in the associated geometry set. For exampld, "seismic station" implies that the node represents a node in the array structure defined by attribute seismic station uid.
Defines a foreign key to table r_seis_acq_vrtx.


seismic_geom_set_s (FSK, M: CHAR VARYING(19))

seismic_acquisition_vertex.seismic_geometry_set
Specifies the geometry set which contains the array whose node is being referenced by this instance. For example, the geometry set which contains the source event uid attribute that the specified uid value is a part of.
Defines a foreign key to table seis_geom_set.


node_name (O: CHAR VARYING(40))

seismic_acquisition_vertex.node_name
Defines the name which would be associated with the node if the detailed acqusition arrays were defined in the associated geometry set.


node_uid (O: INTEGER)

seismic_acquisition_vertex.node_uid
Defines the uid value of the node that this vertex represents. This value must match a value in the attribute implied by ref aquisition vertex in the specified geometry set.
