21. Geo Location (O)

datacite:geoLocation

21.1. Cardinality

Optional

Occurrence: 0-n

21.2. Definition and Usage Instruction

Spatial region or named place where the data was gathered or about which the data is focused.

21.2.1. Property geoLocation (O, 0-n)

Repeat this property to indicate several different locations.

21.2.1.1. Subproperty geoLocationPoint (O)

A point location in space (occurrences: 0-1).

A point contains a single latitude-longitude pair.

See Detailed usage instructions.

21.2.1.1.1. pointLongitude (M)

Longitudinal dimension of point (occurrence: 1).

Mandatory if geoLocationPoint is used.

21.2.1.1.2. pointLatitude (M)

Latitudinal dimension of point (occurrence: 1).

Mandatory if geoLocationPoint is used.

21.2.1.2. Subproperty geoLocationBox (O)

The spatial limits of a place or box (occurrences: 0-1).

Allowed values, examples, other constraints

A box is defined by two geographic points. Left lower corner (normally south west), right upper corner (normally north east). Each point is defined by its longitude and latitude.

See Detailed usage instructions.

21.2.1.2.1. westBoundLongitude (M)

Western longitudinal dimension of box. Mandatory if geoLocationBox is used.

21.2.1.2.2. eastBoundLongitude (M)

Eastern longitudinal dimension of box. Mandatory if geoLocationBox is used.

21.2.1.2.3. southBoundLatitude (M)

Southern latitudinal dimension of box. Mandatory if geoLocationBox is used.

21.2.1.2.4. northBoundLatitude (M)

Northern latitudinal dimension of box. Mandatory if geoLocationBox is used.

21.2.1.3. Subproperty geoLocationPlace (O)

Description of a geographic location (occurrences: 0-1).

Allowed values, examples, other constraints

Free text. Use to describe a geographic location.

21.2.1.4. Subproperty geoLocationPolygon (O)

A drawn polygon area, defined by a set of points and lines connecting the points in a closed chain (occurrences: 0-n).

21.2.1.4.1. polygonPoint (M)

A point location in a polygon (occurrences: 4-n). Mandatory if geoLocationPolygon is used.

21.2.1.4.1.1. pointLongitude (M)

Longitudinal dimension of point (occurrence: 1). Mandatory if polygonPoint is used.

21.2.1.4.1.2. pointLatitude (M)

Latitudinal dimension of point (occurrence: 1). Mandatory if polygonPoint is used.

21.2.1.4.2. inPolygonPoint (O)

For any bound area that is larger than half the earth, define a (random) point inside.

21.2.1.4.2.1. pointLongitude (M)

Longitudinal dimension of point (occurrence: 1). Mandatory if inPolygonPoint is used.

21.2.1.4.2.2. pointLatitude (M)

Latitudinal dimension of point (occurrence: 1). Mandatory if inPolygonPoint is used.

21.2.1.5. Detailed usage instructions

Use WGS 84 (World Geodetic System) coordinates. Use only decimal numbers for coordinates. Longitudes are -180 to 180 (0 is Greenwich, negative numbers are west, positive numbers are east), Latitudes are -90 to 90 (0 is the equator; negative numbers are south, positive numbers north).
