Excavation unit

Excavation unit is a Class that defines artificial Site objects that divides the Archaeological object into smaller units. The Excavation unit is the Find unit's and Find's that facilitate a horizontal and vertical analysis of find distribution. The Excavation unit always belongs to an Archaeological object like for example Cultural layer.

SubClasses

The Excavation unit have two SubClasses:

Artificial stratum - Excavation volumes that are connected and receive Orientation, Size and Position from the Class Square. The Square's Boundary is copied to the Excavation unit.
Free formed stratum - free formed Excavation volumes delimited by the GeoObject type Boundary. Free formed stratum have an optional size and thickness but the Excavation unit is supposed to adjust to the Archaeological object's Boundary/Extension.

Attributes

The Excavation unit has one required Field: Artificial stratum, the remaining properties are optional.

Technical Management of the Class Excavation unit

Excavation units are either measured or created in the Application.

Measure Artificial stratum

Object	Excavation unit the SubClass: Artificial stratum
ObjectId	Is generated from the Point's Point number
Measurement code	Example: 1) 1E2000.17 2) 1E2000,1A
GeoObject type	1 - Point object. When the Artificial stratum is imported it automatically receives a copy of the referred Square's GeoObject as a Boundary (type 2) with the measured Point's Z-value (height).
Class code in the Default template	G (MetaId 12)
SubClass designator in default metadata template	Type - which means the Type of Excavation unit
Object reference	The ObjectId that identifies the Square (2000)
Secondary reference	1) to an ObjectId represents the Archaeological object (17) 2) is the Attribute value (1A) that defines the Artificial stratum's name which is stored in the Database (Artificial stratum must be specified as Default attribute).
Relations	1,2) The contextual Relation is created between the Excavation unit and the Square: 1) if the Artificial stratum has a secondary Object reference a contextual Relation is created between the Excavation unit and the Archaeological Object.

Measure Free formed stratum

Object	Excavation unit the SubClass: Free formed stratum
ObjectId	Is generated from the Object's first Vertex Point number.
Measurement code:	Example: 1) 2G17 2) 2G17,1A
GeoObject type	2 - Boundary / 6 - Sub boundary depending on strategy. 0 - Point in Surface can describe the Excavation units Surface (Terrain model) but you preferably measure the Archaeological object's complete Surface. 4 - Point in Subsurface can describe the Excavation unit's Subsurface but you preferably measure the Archaeological object's Subsurface in parts and measure it after the Excavation unit is excavated. This Subsurface will later constitute the Surface of the contextual Objects below.
Class code in the Default template:	G (MetaId 12)
SubClass designator in default metadata template	Type - which means the Type of Excavation unit
Object reference	The ObjectId that identifies the Archaeological object (17)
Secondary reference	1) is the Attribute value (1A) that defines the Artificial stratum's Name which is stored in the Database (Artificial stratum must be specified as Default attribute).
Relations	1,2) a contextual Relation is created between the Excavation unit and the Archaeological object:

New Excavation unit in Intrasis

If an Artificial stratum is created in the System it is usually created from the Square at which the Excavation unit receives the Square's Geometry and Z-value. We therefore recommend that the Excavation unit's Z-value is specified.
