2.2 Location
This is a mandatory section which defines the spatial location of the monument or site in terms of political, postal, geographic, and cartographic criteria.
Any combination of sub-sections defined below may be employed to identify the location of the monument or site. More than one type of sub-section may be used to more closely determine the location or to make otherwise ambiguous locations more precise. It should be noted that at least one sub-section must be used but that no individual sub-section is mandatory.
2.2.1 Administrative Location
This is an optional sub-section for details of administrative location. It can be repeated.
2.2.1.1 Country or Nation
The name of the country or nation within which the monument or site is located, e.g., France.
(Alphanumeric, Unique, Optional (Mandatory for exchanging data with other countries))
2.2.1.2 Geo-political Unit
This is used for recording the geographical or political subdivisions of countries or nations within which the monument or site is located; for instance Regions in France, Lander in Germany, Counties in Great Britain.
(Alphanumeric, Unique, Mandatory)
2.2.1.3 Administrative Sub-division
This is used for recording the further administrative sub-divisions appropriate to the monument or site. According to the administrative structure of each nation or country, a number of repeat entries in this field may be required. For example, in Great Britain the Country, England, is further subdivided into County, District and Parish, e.g., Wiltshire, Salisbury, Amesbury, and so would require three entries.
(Alphanumeric, Unique, Mandatory)
It should be noted that it is essential to differentiate between the different levels of administrative sub-divisions which relate to each site or monument, e.g., local or regional.
2.2.2 Site Location
This is an optional sub-section which provides for a free-text explanation of the location of the site or monument.
2.2.2.1 Description of Location
A free-text field enabling a short description of the location of a monument or site to be recorded, to assist identification in the field, and to provide a more precise location for sites in sparsely populated or poorly mapped areas.
(Alphanumeric, Unique, Mandatory)
2.2.3 Address
This enables the recording of the location of monuments or sites which have a postal address, especially those within built-up areas. It is an optional sub-section and can be repeated. For example, if the monument or site is located on two streets or has two postal names. All the fields are optional, but at least one must be completed.
2.2.3.1 Name for Address
Purposes Use this field to record the name of the monument or site for address pur-poses (or postal name), e.g., Cruive Cottage.
(Alphanumeric, Unique, Optional)
2.2.3.2 Number in the Street or Road
Use this field for the number of the monument or site in the street or road, e.g., 27A.
(Alphanumeric, Unique, Optional)
2.2.3.3 Name of Street or Road
Use this field for the name of the street or road, e.g., Calea Victoriei.
(Alphanumeric, Unique, Optional)
2.2.3.4 Locality
Use this field for commonly known non-administrative units such as hamlets and townships, e.g., Pincevent.
(Alphanumeric, Unique, Optional)
2.2.3.5 Town or City
Use this field for the name of the town or city, e.g., Stockholm.
(Alphanumeric, Unique, Optional)
2.2.3.6 Postal or Other Similar National Address Code
Use this field to record an address code, e.g., 670000, K1A OC8
(Alphanumeric, Unique, Optional)
2.2.4 Cadastral Reference/Land Unit
Some countries operate a system of allocating reference numbers to individual blocks or units of land. The land unit reference number relevant to the particular monument or site can be entered here. This field is optional and can be repeated.
2.2.4.1 Cadastral Reference
This field enables cross reference to the land unit or parcel(s) current in some nations or countries, e.g., block reference 941\278.
(Alphanumeric, Unique, Mandatory)
2.2.5 Cartographic Reference
This is an optional sub-section used to record the two- or three-dimensional or spatial co-ordinates required for locating the monument or site within the mapping system(s) used by individual countries or nations. The four fields 2.2.5.5-8 should be repeated for each set of co-ordinates.
2.2.5.1 Cartographic Identifier
The identifier of the cartographic entity where the monument or site has more than one such entity related to it, e.g., polygon 1.
(Alphanumeric, Unique, Optional)
2.2.5.2 Spatial Referencing System
This field specifies the spatial or cartographic referencing system employed, e.g., UTM, Lambert, GPS, Ordnance Survey.
(Alphanumeric, Unique, Mandatory)
2.2.5.3 Topology
This field specifies whether the spatial co-ordinates given relate to a point, line, or area, e.g., P, L, A.
(Alphanumeric, Unique, Mandatory)
2.2.5.4 Qualifier
This field allows for an indication of the significance and reliability of the cartographic or spatial co-ordinates for a site or monument, e.g., approximate, centre. Controlled vocabulary is desirable.
(Alphanumeric, Unique, Mandatory)
The following four fields should be repeated for each co-ordinate.
2.2.5.5 Sequence Number
When an archaeological site or monument is of linear or polygonal shape, it is advisable to list a series of sets of co-ordinates describing its course rather than a single reference to, for example, its central point. These should be listed in sequence. The sequence number for each set of co-ordinates should be entered here. For example, 1 for a point, 1,2 for a line and 1,2,3 for a polygon.
(Alphanumeric, Unique, Mandatory)
2.2.5.6 Z Coordinate
Value or identifier of cartographic reference. It locates a record in relation to a vertical datum, e.g., 30 metres above sea-level, 30 metres below chart datum for underwater sites.
(Alphanumeric, Unique, Optional)
2.2.5.7 X Coordinate
Value or identifier of cartographic reference. This is normally the east-west coordinate.
(Numeric, Unique, Mandatory)
2.2.5.8 Y Coordinate
Value or identifier of cartographic reference. This is normally the north-south coordinate.
(Numeric, Unique, Mandatory)
