ARCHAEOLOGY,Archaeological feature. Surveyed extents of archaeological features located during excavation. Labelled with a wessex  codelist or a user defined label. See Attribute Label Codes column for details.,"Pre-ex: Feature surveyed prior to excavation. Ditch: On site interpretation ditch feature. Pit: On site interpretation pit feature. Gully: On site interpretation gully feature. Post-Hole: On site interpretation post-hole feature. Other: Any other archaeological feature identified on site, labelled with a user defined label.","ARCHAEOL_LEVEL layer label is survey point height in MAOD
ARCHAEOL_LABEL; Descriptive  label layer annotated with feature type . ",AY
AREA,Surveyed area layer. Labels a specific area of survey. Usually the excavated site extents  but also project specific site sub-divisions or targeted areas of intervention/interest. ,"Strip: Area of site stripped of topsoil/subsoil by machine excavation. Usually delimits site. Layer: Area delimiting the extent of an interpreted archaeological layer. Spread: Used to survey the extents of a  deposited spread of archaeological material. Other: Any other area surveyed on site, labelled with a user defined label. ",Area label. Descriptive or number in format. Numbered and labelled with attribute label. See Attribute Label Codes column for details.,AR
CONTEXT,Context & Centre Point surveyed point usually at the base of an archaeological feature's cut to level in m above Ordnance Datum. Identifies archaeological features by their project unique context cut number.  ,,"CONTEXT_LEVEL layer label is survey point survey point height in MAOD
CONTEXT_LABEL; Context number label layer:  Numbers prefixed with CP (Centre Point). ",CP
DISTURBANCE,"Disturbance, usually modern that has impacted on the natural that underlies the subsoil and in many cases the visible archaeology. Labelled with attribute label denoting type of disturbance. See Attribute Label Codes column for details.","Land Drain: Modern agricultural land drains identified on site.

SLOT,Surveyed line delimiting the extent of an excavation made into an archaeological feature for recording and finds retrieval (termed as an Archaological Intervention) made by an Archaeologist on site. ,,Slot label:  User created attribute label indicating the cut context number of the archaeological feature. Often used without a label  to record the excavated area during investigation on site.,SO
