Complex Type irm:BoundingGeometryType

Namespace | urn:us:gov:ic:irm
Annotations | ? Type that defines a GML compliant bounding geometry. See ISO 19115 EX_BoundingPolygon. Developer's Note: It is required that the srsName attribute be populated on a gml:Point or gml:Polygon element within the IRM. Recommended values for the attribute are: 1) http://metadata.ces.mil/dse/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 2) http://metadata.ces.mil/mdr/ns/GSIP/crs/WGS84E_2D -- representing World Geodetic System 1984 - Geographic, 2-Dimensional, where latitude is north positive, measured in degrees; and latitude is east positive, measured in degrees. OR 3) http://metadata.ces.mil/dse/ns/GSIP/crs/WGS84E_3D -- representing 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. 6. The outside edge of a linearRing is defined by four or more coordinate tuples, in counter- clockwise order, with linear interpolation between them; the first and last coordinates must be identical. 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.
