cbrn:GeographicPoint

A set of geographical coordinates providing latitude, longitude, and elevation (at the point of measurement and at the point on the earth's surface), and uncertainty of the coordinates.

cbrn:GeographicPoint holds other objects.

cbrn:GeographicPoint can hold any of these following objects, starting with the most specific and becoming more generic as you move down the list:


cbrn:LatitudeValue

A point's latitude on the surface of the earth expressed as geographic coordinates in decimal degrees. Points in the northern hemisphere range from 0.0 to +90.0 degrees. Points in the southern hemisphere range from 0.0 to -90.0.

Holds numbers.


cbrn:LongitudeValue

A point's longitude on the surface of the earth expressed in decimal degrees. Points east of the prime meridian range from 0.0 to +180.0 degrees. Points west of the prime meridian range from 0.0 to -180.0.

Holds numbers.


cbrn:ElevationValue

A value for the elevation of a GeographicPoint in meters relative to the applicable datums ellipsoid.

Holds numbers.


cbrn:ElevationOffsetValue

A value for the difference between the Elevation at a point of coordinate measurement and the earth's surface in meters.

Holds numbers.


cbrn:GeoPointAccuracyValue

An estimated 1-sigma positional accuracy in meters (m) of a geographic point described by the latitude and longitude coordinates of the point.

Holds numbers.


cbrn:ElevationAccuracyValue

A value for the estimated accuracy of the elevation of a geographic point.

Holds numbers.


cbrn:ElevationOffsetAccuracyValue

A value for the estimated accuracy of the elevation offset vertically to the earth's surface from a geographic point.

Holds numbers.


@cbrn:datumText

A value identifying the spatial reference system in which geographic coordinates are stated. Default is WGS-84.

Holds text.


@cbrn:unitsText

A unit of measure for a value element. If used, the unit of measure shall be as stated in the documentation for the element.

Holds code table entries.


cbrn:RemarkText

A placeholder for comments intended to help the consumer of the data to understand better the information encapsulated by the parent element.

Holds text.
