This is useful in comparing the proposed / planned survey lines with the acquired data. The feature class also hyperlinks to acquired survey data files.	Shot PtsThe survey shot points feature class (often also called event fixes) are used to position features and events along geophysical survey lines. This feature class stores these values in addition to the M-values stored in the Survey_Tracklines feature class geometry.	Sounding GridThe survey souding grid feature class stores survey soundings or gridded elevations as individual point features. Due to the volume of data acquired in some bathymetric surveys, sounding grids are also often delivered or stored as raster datasets or external *xyz files instead.	Bathy ContoursThe bathymetry contours feature class stores major and minor water depth / elevation contours.	Chart IndexThe chart index map feature class serves as a helper class to hyperlink users to externally generated maps, charts, and alignment drawings. It stores document control, scale, paper size, and other information helpful to the user in determining the extents of generated charts and alignment panels.	Prop LinesThe Proposed Survey Run Line feature class captures pre-survey planned, or proposed (sometime also called ???pre-plot???) survey lines. This captures useful features important for both survey planning as well as post-survey confirmation.	Equip LimitsThe survey equipment limits feature class captures the outlines of surveyed data separated by survey sensor. This is useful for storing the limits of multi-sensor geophysical surveys (i.e. SSS and MBES) whose data extents may not be identical or in confirming the surveyed are against the original scope of work/key sheet.	KeysheetThe survey keysheet captures the outline of an area to be or already surveyed as well as administrative-level data about survey contractors, data quality standards, and data hyperlinks.	Seabed PntThe seabed feature point class stores smaller point-type features such as sonar contacts or coral pinnacles. These features help characterize a field environment and define risks to field development and infrastructure placed on the seabed.	Seabed ArcThe seabed feature line class is used for linear or elongated seabed features such as anchor scars or scarps. These features help characterize a field environment and define risks to field development and infrastructure placed on the seabed.	Seabed PlyThe seabed feature polygon feature class is used to store locations of larger, area-based seabed features such as well cuttings areas or mass transport deposits. These features help characterize a field environment and understand risks to field development and infrastructure placed on the seabed.	Slope PntSlope Label Points is a ???helper??? class in the context of GIS cartography. It is common that slope analysis is performed with bathymetry data and locations with steep slopes are highlighted on the map. The Slope Label Points feature class provides a convenient table to hold the gradient data so that it can be labelled in the GIS	Sed PriThe data source could be from seabed classification based on sonar backscatter, side-scan sonar, or interpolated using sediment data from geotechnical sampling /	Sed SecThe data source could be from seabed classification based on sonar backscatter, side-scan sonar, or interpolated using sediment data from geotechnical sampling /	Acoustic PntAcoustic Features represented as points. These are seismic amplitude anomalies interpreted from the high resolution seismic images. Amplitude anomalies provide a good indication of the presence of shallow gas that can pose a risk to the drilling of wells and the pinning of jack-up rig legs.	Acoustic PlyAcoustic Features represented as polygons. These are seismic amplitude anomalies interpreted from the high resolution seismic images. Amplitude anomalies provide a good indication of the presence of shallow gas that can pose a risk to the drilling of wells and the pinning of jack-up rig legs.	Fault PntThe fault point feature class stores points representing fault picks or fault label point in shallow and intermediate subsurface geologic zone. Active subsurface faults can pose a risk to field development and are an important part of establishing baseline geologic conditions.	Fault ArcThe fault arc feature class stores traces or linear surface expressions of fault surfaces represented as linear features. Active subsurface faults can pose a risk to field development and are an important part of establishing baseline geologic conditions.	Fault PlyThe fault polygon feature class stores polygons representing fault surfaces or areas in shallow and intermediate geologic zone. Active subsurface faults can pose a risk to field development and are an important part of establishing baseline geologic conditions.	Geologic PntThe geologic feature point feature class stores the locations of subsurface pick and can act as a ???helper??? class as a label point for geologic features within shallow or intermediate geologic zone. Characterization of the geology of a field is important in evaluating the risks that subsurface geohazards pose to field development.	Geologic ArcThe geologic feature line stores the linear expression or trace of a geologic feature within shallow or intermediate geologic zone (i.e. buried channel or erosional surface). Characterization of the geology of a field is important in evaluating the risks that subsurface geohazards pose to field development.	Geologic PlyThe geologic feature polygon feature class stores the area outlines representing traced surface or area of a geologic feature within shallow or intermediate geologic zone (i.e. salt domes or gas-charged sediments). Characterization of the geology of a field is important in evaluating the risks that subsurface geohazards pose to field development.	IsochronThe isochron contours feature class maps the acoustic travel times between two reflectors or between the seafloor and a given reflector.	IsopachThe isopach contours feature class maps the thickness of a given stratigraphic unit or group of units.	Struct Contours	Line ProfileAs with the Slope Label Points, Line of Profile is also a ???helper??? class that assists in depicting the existence of a cross-section or seismic line section for the purpose of charting or for hyperlinking in a GIS environment	Paleo PntThe paleo-channel system point feature class can represent individual picks along a paleochannel system and can also act as a ???helper??? class representing a label point for a subsurface paleo-channel system.	Paleo ArcThe paleo-channel system polyline feature class stores the outlines or traces of a subsurface paleo-channel system. Characterization of the geology of a field is important in evaluating the risks that subsurface geohazards pose to field development.	Paleo ContourThe paleo channel system contours feature class maps the depth of a buried channel system???s surface. Characterization of the geology of a field is important in evaluating the risks that subsurface geohazards pose to field development.	Paleo PlyThe paleo channel system polygon feature class represents the area extent of a subsurface paleo-channel system. Characterization of the geology of a field is important in evaluating the risks that subsurface geohazards pose to field development.	Env Sample	GeochemGeochemical sampling at the seabed can be used as a prospecting tool for identifying the presence of hydrocarbons from deeper source rocks.	GeotechGeotechnical Sample class caters for shallow samples such as soil sampling using grab, drop, piston or vibro coring, and also seabed cone-penetration testing (all usually 0-30m depth from seabed), and also full rotary-based geotechnical boreholes, usually up to 150m depth. In the case of boreholes, the subtypes are available for in-situ test only, and combination of both soil sampling and in-situ test. Pilot hole is also a subset for Geotechnical Sample.	Heat FlowHeatflow measurements characterize background heat flow to constrain geochemical models and provide additional data on regional hydrodynamics and hydrocarbon occurrence.	TS DipThe collection of Sound Velocity / Temperature-Salinity (T-S Dip) Profiles is crucial in any hydrographic survey. Depending on which acoustic equipment is being used, O&G companies may chart the first measurement nearest to the sea surface only or, more commonly, require a whole profile of Temperature-Salinity data from surface to seabed, at a specific interval, e.g. every one metre.	Video TrackVisual inspections from ROV or AUV surveys can provide visual confirmation of features for asset integrity (i.e. pipeline) or environmental feature investigations.
