latitude/longitude info in a GML Bounding box -


Text after "

, for example, we are box bounding as given below in GML:

< Code> & lt; GML: envelope & gt; & Lieutenant; GML: Lower Corner & gt; 42,943-71,032 & lt; / Gml: Lower Corner & gt; & Lieutenant; GML: Upper Corner & gt; 43.039 -69.856 & lt; / Gml: Upper Corner & gt; & Lt; / GML: envelope & gt;

Now, for the lower corner, wood value is latitude and longitude wood. This information could not be found in the online document.

Thanks Stroller

GML is formatted in GeoRSS

< P> From the GML schema:
  & lt; Complex type name = "envelopeType" & gt; And lieutenant; Options & gt; And lieutenant; Sequence & gt; & Lieutenant; Element name = "lowercondar" type = "gml: directpressation type" /> & Lieutenant; Element name = "upper corner" type = "gml: directpressation type" /> & Lt; / Sequence & gt; & Lieutenant; Element riff = "gml: mail" minicomers = "2" max ockers = "2" & gt; And lieutenant; Annotation & gt; And lieutenant; App Info & gt; Deprecated & lt; / App Info & gt; & Lt; / Annotation & gt; & Lt; / Element & gt; & Lieutenant; Element ref = "gml: coordinate" /> & Lt; / Options & gt; & Lieutenant; Specialty Group Referee = "GML: SRSERFRUS Group" /> & Lt; / ComplexType & gt; And lieutenant; Element name = "envelope" type = "GML: envelopeType" substitutionGroup = "GML: abstract object" & gt; And lieutenant; Annotation & gt; And lieutenant; Documentation & gt; The envelope defines an extent by using a pair of conditions defining the opposite edges in arbitrary dimensions. The first direct "lowest corner" (for all the points within each coordinate position of the coordinates of all the dimensions for continuous matter on the envelope), the second one "upper corner" (for a coordinate position of all the greater coordination The constant thing is for every point within the envelope for each dimension). The use of "coordinate" and "mail" properties is disliked. Clearly named properties "Lower Corner" and "Upper Corner" will be used instead. & Lt; / Documentation & gt; & Lt; / Annotation & gt; & Lt; / Element & gt;   

Which leads to the SRS ArrayFure Group which contains the code so that you can see axis orders and units (among other things) about your coordinates.

  & lt; Specialty Group Name = "SRSReferenceGroup" & gt; And lieutenant; Annotation & gt; And lieutenant; Documentation & gt; The specialty group SRSReferenceGroup is an alternative reference for the CRS used by this geometry, to simplify the processing of coordination with additional additional information when more complete definition of CRS does not normally require a CRS of specialty srsName GRL For example, indicates: Abstrack Coordinate Reference System. For famous contexts, it is not necessary that the CRS statement is present in place of the URI. If no srsName attribute is given, the CRS will be specified as part of a larger context. This is part of the geometry element. & Lt; / Documentation & gt; & Lt; / Annotation & gt; & Lieutenant; Attribute name = "srsName" type = "anyURI" /> & Lieutenant; Attribute name = "srsDimension" type = "positiveInteger" /> & Lieutenant; Specialty Group Rif = "GML: SRSI Group Group" / & gt; & Lt; / AttributeGroup & gt;   

So it is impossible to answer your question without a specified SRS, we do not even know which unit your coordinates are
