I am trying to 1) Read an NZMG raster, reproject it to NZTM and write it out: try { File rasterFile = new File("TestData/heathcote_200_depth.png"); WorldImageFormat format = (WorldImageFormat) GridFormatFinder.findFormat( rasterFile ); AbstractGridCoverage2DReader reader = format.getReader(rasterFile); GridCoverage2D myGridCov = reader.read(null); GridCoverage2D reprojected = (GridCoverage2D) Operations.DEFAULT.resample(myGridCov, CRS.decode("EPSG:2193)); WorldImageWriter wir = new WorldImageWriter(new File("TestData/heathcote_NZTM.png")); wir.write(reprojected, null); } catch (Exception e) { …… } IN this case the code just hangs after the reproduction. No error messages, nothing. It just sits there till I hace to kill it. and 2) Read an NZTM raster, reproject it to NZMG and write it out: try { File rasterFile = new File("TestData/mis100yearmpdcc_maxdepth_NZMG.tif"); GeoTiffFormat format = (GeoTiffFormat)GridFormatFinder.findFormat( rasterFile ); AbstractGridCoverage2DReader reader = format.getReader(rasterFile); GridCoverage2D myGridCov = reader.read(null); GridCoverage2D reprojected = (GridCoverage2D) Operations.DEFAULT.resample(myGridCov, CRS.decode("EPSG:27200")); GeoTiffWriter wir = new GeoTiffWriter(new File("TestData/miss100.tif")); ParameterValueGroup params = format.getWriteParameters(); GeneralParameterValue[] wps = (GeneralParameterValue[]) params.values().toArray(new GeneralParameterValue[1]); wir.write(myGridCov, wps); } catch (Exception e) { ………. } In this case, I get the error message java.lang.IllegalArgumentException: Unable to map projectionNew_Zealand_Map_Grid at org.geotools.coverage.grid.io.imageio.geotiff.CRS2GeoTiffMetadataAdapter.parseCoordinateProjectionTransform(CRS2GeoTiffMetadataAdapter.java:739) at org.geotools.coverage.grid.io.imageio.geotiff.CRS2GeoTiffMetadataAdapter.parseProjection(CRS2GeoTiffMetadataAdapter.java:290) at org.geotools.coverage.grid.io.imageio.geotiff.CRS2GeoTiffMetadataAdapter.parseProjCRS(CRS2GeoTiffMetadataAdapter.java:241) at org.geotools.coverage.grid.io.imageio.geotiff.CRS2GeoTiffMetadataAdapter.parseCoordinateReferenceSystem(CRS2GeoTiffMetadataAdapter.java:176) at org.geotools.gce.geotiff.GeoTiffWriter.write(GeoTiffWriter.java:251) at riskscape.map.internal.render.DataImageTest.testReprojectFileNZTMToNZMG(DataImageTest.java:119) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:45) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:42) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:263) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:68) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:47) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:231) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:60) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:229) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:50) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:222) at org.junit.runners.ParentRunner.run(ParentRunner.java:300) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) Any ideas on how to proceed?

I've figured out what I was doing wrong when trying to write to file the reprojected geotiff file, but I am still stuck of with writing out the reprojected world image PNG -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Cannot-save-reprojected-georeferenced-raster-to-file-tp5068102p5068104.html Sent from the geotools-gt2-users mailing list archive at Nabble.com. |
