must be searched for a particular object. For

Asserts that all seismic station uids have the
same line index associated with them. This is
the index which varies in the "crossline" direction.
If this attribute is specified, then acquisition
index should not specify a value for "acquisition
line index".
channel_connection N ndt_uid_array
Defines a "receiver uid" value at each node of
the 2D grid defined by field trace grid. This
defines which receiver facility was utilized to
record each field trace. This asserts fixed facility
recording (e.g., land). A pair of values including
"seismic geometry set uid" may be defined when
"receiver uid" values from many seismic geometry
sets are specified.
channel_facility N ndt_uid_array
Defines the sensor (i.e., receiver, uphole sensor,
etc.) connected to each channel by specifying
a "seismic facility uid" value at each node of
the grid defined by channel uid. This asserts
that the channel to receiver association was not
transient (e.g., marine). The grid used must match
the grid defined by channel uid. Each "seismic
facility uid" value must match the value of attribute
seismic facility uid in one of the facilities
referenced in seismic facility.

Defines the receiver facility representing each
receiver by specifying a "seismic facility uid"
at each node of the grid defined by receiver uid.

the value of attribute seismic facility uid in
one of the facilities referenced in seismic facility.

node of the grid defined by receiver uid. This
defines the location of each receiver facility.

ref_naming_system ref_naming_system

as unique.

2D survey, refraction survey, uphole survey, checkshot
survey, 2D line, source line, receiver line, derived
3D survey (e.g., 2.5D), derived 2D survey (e.g.,
array simulation using kilochannel data). A "survey"
(or 2D line) will normally be at the top of the
composition hierarchy: however, "surveys" can
be composed of "surveys" (e.g., an "irregular"
3D survey could be composed of multiple "regular"
3D surveys or a 2D line could be extended by another
2D line).
ref_survey_environment ref_survey_environment
The environment in which the data were acquired.
Examples include: marine, marine with cross-current,
land, swamp, transition zone, wellbore, etc.
seismic_geometry_set_uid ndt_user_unique_identifier
A user assigned unique identifier of the geometry
set. There is no semantic meaning implied by the
value other than uniqueness within a user controllable
scope of the data store. This value can be used
within "arrays" of information as an implied
relationship to this geometry set. This value
must be unique within the scope of the data which
points at it. The scope is generally within a
survey but when geometry sets are derived from
other geometry sets, the data in the new geometry
set may point to geometry in the original geometry
sets. It is not a problem for geometry sets within
different surveys to have non-unique uid values
unless information in those surveys will be combined.
This of course assumes that applications faithfully
populate the "usage" relationships which allow
the scope to be explicitly determined.
source_event_name N ndt_name_array

names should be unique within the array. The grid
used must match the grid used by source event
uid.

facility uid in one of the facilities referenced
in seismic facility.
source_station N ndt_uid_array
Defines a "seismic station uid" value at each
source event. The grid used must match the grid
used by source event uid. A pair of values including
"seismic geometry set uid" may be defined when
"seismic station uid" values from many seismic
geometry sets are specified.
station_name N ndt_name_array
The name associated with each seismic station.
The grid used must match the grid used by seismic
station uid. The names should be unique within
the array.

(e.g., for VSP).
channel_uid grid_1d_equal
Defines a 1D grid which specifies a "channel uid"
value at each node. The same grid can be used
by many other attributes which assign information
to a channel. There is no semantic meaning implied
by the "uid" value.

Defines the geometry that was used to derive this
geometry. For example, a "2.5D survey" is derived
from a set of "2D lines". Note that the new geometry
set may not define any new acquisition geometry
but rather the data associated with it may reference
the original acquisition geometry and a new processing
geometry.
field_trace_grid grid_defined_grid
Defines a 2D grid composed of the grids defined
by channel uid and source event uid. This grid
represents recorded field traces.

and may be represented by a single typical facility.
geophysical_acquisition_area U geophysical_acquisition_area

set. If the area does not identify the geometry

set is a part.
receiver_uid grid_1d_equal
Defines a 1D grid which specifies a "receiver
uid" value at each node. This represents fixed

value.
seismic_station_uid grid_1d_equal
Defines a 1D grid which specified a "seismic station
uid" value at each node. Each node represents
a surveyed station (e.g., land). There is no semantic
meaning implied by the "uid" value.
source_event_uid grid_1d_equal
Defines a 1D grid with a "source event uid" value
specified at each node. Each node represents a
different source event. The same grid can then
be used by many other attributes which assign
information to a source event. There is no semantic
meaning implied by the "uid" value.
