Hello,
I'm trying to load geotiff files with the following codes but for both I
get an error :
- "java.lang.UnsupportedOperationException: Only Geographic & Projected
Systems are supported. (not code 0)
at
org.geotools.gce.geotiff.GeoTiffCoordinateSystemAdapter.createCoordinateSystem(GeoTiffCoordinateSystemAdapter.java:277)
at org.geotools.gce.geotiff.GeoTiffReader.read(GeoTiffReader.java:216)
at test.GeotiffTest.test2(GeotiffTest.java:77)
at test.GeotiffTest.main(GeotiffTest.java:27)
I've tried to load the files with ArcExplorer (Java Edition) and
everything seems to be ok.
Files are using the Lambert2Etendu coordinate system.
Any idea how to make it works because it's the last thing I've have to do...
Thank's
Jérémy DE ROYER
