X and Y axes inverted (imageCRS subset) #7

Closed constantinius closed 11 years ago

X and Y axes are inverted in the GML of multipart GetCoverage responses with imageCRS subsetting.

http://localhost:8000/ows?service=wcs&version=2.0.0&request=GetCoverage&coverageid=mosaic_MER_FRS_1P_RGB_reduced&format=image/tiff&mediatype=multipart/mixed&subset=x%28100,200%29&subset=y%28100,200%29

In addition axis ordering in GetCoverage requests to Datasets is different than in requests to Mosaics.

Applies to XML elements Footprint and contributingFootprint in !GetCoverage requests to Datasets vs. !StitchedMosaics

Quote from OGC 10-157r1 EO O&M, note especially the footnote:

8.1.3 Footprint The eop:Footprint block contains description of the target location observed during the !EarthObservation.

Complete description of eop:Footprint is given in Table 7.

||Field name||Field description||Cardinality|| ||multiExtentOf||Acquisition footprint coordinates, described by a closed polygon (last point=first point), using latitude, longitude pairs. Expected structure is gml:Polygon/gml:exterior/gml:LinearRing/gml:pos List.^1||1||

||orientation||Determines the orientation of the coordinate pairs for the exterior boundary of the footprint polygons. Possible values are CW (clockwise), counter-clockwise (CCW) or OTHER (unspecified orientation). Note that this property is only to be provided for footprints that do not follow the normal counterclockwise for exterior boundaries convention as defined in [OGC06-103r4]. If the property is not provided, a CCW orientation for the exterior boundary will be assumed.||0..1|| ||centerOf||Acquisition center coordinates||0..1||

1 The Polygon geometry shall be encoded in the WGS:84 geographic coordinates (EPSG:4326). The coordinate pairs shall be ordered as lat, long following the official axis ordering convention.

Adjusted axis ordering when importing from EO-O&M footprint with r1135.

In gml:BoundedBy and RectifiedGrid origin elements, the axis order has to be changed

Fixed in MapServer with [http://trac.osgeo.org/mapserver/changeset/13156]. Final fixes for offsetVector elements will be commited soon.

Fixed offsetVector in MapServer with http://trac.osgeo.org/mapserver/changeset/13286 and http://trac.osgeo.org/mapserver/changeset/13287.

Hopefully finally fixed with r1570 and r1571.
