Element irm:boundingGeometry

Namespace | urn:us:gov:ic:irm
Annotations | ded:Definition: An element under geospatialCoverage for child elements used to express a geographic location as one or more points (using coordinates) or one or more polygons (a set of connected coordinates). Models a TSPI compliant bounding geometry. See TSPI 2.0 Polygon. Developer's Note: It is recommended that the srsName attribute be populated on a gml:Point or gml:Polygon element within the IRM. Recommended values for the attribute are: http://metadata.dod.mil/mdr/ns/GSIP/crs/WGS84C_3D representing World Geodetic System 1984 - Earth Centered, Earth Fixed (ECEF), where the X axis is mass center - equator/prime meridian, and the units are meters; the Y axis is mass center - equator/90? E, and the units are meters; and the Z axis is mass center - North Pole, and the units are meters. OR http://metadata.dod.mil/mdr/ns/GSIP/crs/WGS84E_2Drepresenting World Geodetic System 1984 - Geographic, 2-Dimensional, where latitude is north positive, measured in degrees; and latitude is east positive, measured in degrees. OR http://metadata.dod.mil/mdr/ns/GSIP/crs/WGS84E_3Drepresenting World Geodetic System 1984 - Geographic, 3-Dimensional, where latitude is north positive, measured in degrees; and latitude is east positive, measured in degrees; and height is height above ellipsoid, measured in meters. See also: http://earth-info.nga.mil/GandG/publications/tr8350.2/tr8350_2.html For gml:pos elements populating the gml:Polygon/gml:exterior/gml:LinearRing/gml:pos element the following guidance should be followed: 1. Latitude shall be in decimal degrees in the range -90? less than or equal to latitude greater than or equal to +90?. 2. North latitudes shall be positive, south latitudes shall be negative. 3.Longitude shall be in decimal degrees in the range -180? less than or equal to longitude greater than or equal to +180?; note that there are two equally acceptable values of longitude for the meridian opposite the prime meridian. 4. East longitudes shall be positive, west longitudes shall be negative. 5. Only the element gml:pos shall be used to encode a geographic point location as either: a. two decimal values in the order of latitude then longitude (no commas) when WGS84E_2D, or b. three decimal values in the order latitude, longitude and finally height above ellipsoid (no commas) when using the WGS84E_3D CRS. Developer's Note: The srsName attribute is required on the Polygon element. The Polygon/@srsName is the identifier for the CRS which is controlling for the child gml:pos elements. It is important to note that the srsName attribute may also appear on the gml:pos elements, however given the current allowable CRSs above there is no need to repeat the information on the gml:pos elements thus the srsName attribute is optional and not required. If the srsName does appear on the gml:pos elements then it must be the same as the value of the srsName attribute on the Polygon element. ded:Obligation: (Conditional) geospatialCoverage must have at least one of geographicIdentifier, boundingGeometry, or postalAddress. ded:Comment: This element must contain at least one element (tspi:Polygon, tspi:Point, tspi:Envelope, tspi:Circle, or tspi:Ellipse). The schema permits an unbounded number of boundingGeometry elements, and each boundingGeometry element can have an unbounded number of geometry elements. This element must also be used in instances where a bounding polygon is to be specified using a Coordinate Reference System other than WGS-84. The currently acceptable Coordinate Reference Systems are: (1) World Geodetic System 1984 - Earth Centered, Earth Fixed (ECEF), identified by the URI: "http://metadata.dod.mil/mdr/ns/GSIP/crs/WGS84C_3D". (2) World Geodetic System 1984 - Geographic, 2-Dimensional, identified by the URI: "http://metadata.dod.mil/mdr/ns/GSIP/crs/WGS84_2D". (3) World Geodetic system 1984 - Geographic, 3-Dimensional, identified by the URI: "http://metadata.dod.mil/mdr/ns/GSIP/crs/WGS84_3D". These URI values are the values to be populated in the srsName attribute of the tspi:Point and tspi:Polygon elements. Details for the structure and encoding of these elements are detailed in the TSPI specification.
