I wouldlike to create a layer with all my tiles of ortho (jpeg2000). The problem here is the georeference of each jpeg2000 file are in .jgw file. When I try to add this on geoserver, I have always the same error:

Caused by: org.opengis.referencing.operation.OperationNotFoundException: Aucune transformation du système "EngineeringCRS[Wildcard 2D cartesian plane in metric unit]" vers "GeographicCRS[WGS84(DD)]" n'est disponible.

  • You have no projection, either use gdal to convert to GeoTIFF or add a.prj file to each one

  • @IanTurton Ok thanks for you're answer ! How can I convert to GeoTIFF ? By using Image data sources then GeoTIFF - Tagged Image File Format with Geographic information ?

Your JP2k files are missing their projection information. There are two solutions

  1. add a .prj file to each file. I wrote a program and a blog post about how to add .prj files to large groups of rasters to solve this problem.

  2. Convert your files to a format with the projection and georeferencing metadata included in it. Normally, the GeoServer community recommend you use GeoTiffs with compression, tiling and overveiws.
