Hi, The GML to slip in into JPEG2000 looks about like this:
<gml:FeatureCollection xmlns:gml="http://www.opengis.net/gml"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.opengis.net/gml http://www.math.ubc.ca/~burggraf/gml/gml4jp2.xsd";> <gml:boundedBy> <gml:Null>withheld</gml:Null> </gml:boundedBy> <gml:featureMember> <gml:RectifiedGridCoverage dimension="2" gml:id="RGC0001"> <gml:rectifiedGridDomain> <gml:RectifiedGrid dimension="2"> <gml:limits> <gml:GridEnvelope> <gml:low>0 0</gml:low> <gml:high>11999 11999</gml:high> </gml:GridEnvelope> </gml:limits> <gml:axisName>x</gml:axisName> <gml:axisName>y</gml:axisName> <gml:origin> <gml:Point gml:id="P0001" srsName="urn:ogc:def:crs:EPSG::3067"> <gml:pos>356000.2500000000000 7595999.7500000000000</gml:pos> </gml:Point> </gml:origin> <gml:offsetVector srsName="urn:ogc:def:crs:EPSG::3067">0.5000000000000 -0.0000000000000</gml:offsetVector> <gml:offsetVector srsName="urn:ogc:def:crs:EPSG::3067">-0.0000000000000 -0.5000000000000</gml:offsetVector> </gml:RectifiedGrid> </gml:rectifiedGridDomain> </gml:RectifiedGridCoverage> </gml:featureMember> </gml:FeatureCollection> You can write such by hand but it is not a pleasure. - You will need to know the image dimensions in pixels for setting gml:low and gml:high - Anchor point of gml:origin is in the middle of the corner pixel. In the example origin is in the top left corner and coordinates in EPSG:3067 are presented in Easting-Northing direction. Be aware that the axis order must match the official EPSG definitions and for example for EPSG:4326 it is Latitude-Longitude. - In the example offset vectors go from West to East and from North to South at 0.50 m steps but because the North coordinate is decreasing by each step the offset vector shows negative value. I believe that I wouldn't bother to go that way if world files (.j2w of .wld) would do the job possibly together with .prj for defining the projection. There are also different interpretations about the anchor point of gml:origin. One major image processing software is using the corner of the corner pixel as an anchor point and I have not seen a straight answer to which interpretation is correct. GDAL believes in the centre of a pixel. I try to avoid using GML in JPEG2000 even it is an OGC standard. -Jukka Rahkonen- t.przysiwek wrote: > Hi, > > thanks for your help. > > I got a lot of jp2 files (about 5000) generated via Kakadu and if possible I > would > like to not manipulate on pixels and just batch insert geolocation data > inside. > The only data I've got for files, are coordinates like: > 52.700178,6.277880 > 52.662452,6.277880 > 52.662452,6.301401 > 52.700178,6.301401 > > In my opinion, solution suggested by Rahkonen Jukka (GML attach 1.1) is what I > need, but how to correctly generate gml file, f.e. calculate offsetVector: > > > > > -- > View this message in context: http://osgeo-org.1560.x6.nabble.com/Adding- > JP2-raster-layer-to-server-tp5090126p5091405.html > Sent from the GeoServer - User mailing list archive at Nabble.com. > > ------------------------------------------------------------------------------ > Rapidly troubleshoot problems before they affect your business.
