Hello Christian, and thanks for your quick reply. I'm writing an application which should be able to deal with such big data (either in GRID or in TIFF).
I know that there are tools like gdal which are able to build tiles and so on, but I need my application (written in Java) to be able to deal with the whole file. Of course, I do not try to load it in memory, but I wish to read it to make some geo-processing. Regards, César 2009/10/2 Christian Müller <[email protected]>: > What do you want to do with this large image in memory ? > I never worded with ArgGrid rasters but I would suggest you download > http://fwtools.maptools.org/ > and use gdal_retile.py to build tiles and pyramids. Afterwards you can use > the geotools imagemosaic mdoule to process the tiles from the file system or > imagemosaic-jdbc to do the same having the tiles in a jdbc database. > > > > César Martínez Izquierdo writes: >> >> I need to process huge rasters with GeoTools, but it seems I've found >> its limit :-( >> INFO: Unable to find crs, continuing with default WGS4 CRS >> Exception in thread "main" java.lang.IllegalArgumentException: >> Dimensions (width=59000 height=46000) are too large >> at java.awt.image.SampleModel.<init>(SampleModel.java:112) >> at >> java.awt.image.ComponentSampleModel.<init>(ComponentSampleModel.java:128) >> at >> javax.media.jai.ComponentSampleModelJAI.<init>(ComponentSampleModelJAI.java:73) >> at >> javax.media.jai.FloatDoubleColorModel.createCompatibleSampleModel(FloatDoubleColorModel.java:1003) >> at >> it.geosolutions.imageio.plugins.arcgrid.AsciiGridsImageReader.initializeReader(AsciiGridsImageReader.java:344) >> at >> it.geosolutions.imageio.plugins.arcgrid.AsciiGridsImageReader.setInput(AsciiGridsImageReader.java:320) >> at >> org.geotools.gce.arcgrid.ArcGridReader.<init>(ArcGridReader.java:184) >> at >> org.geotools.gce.arcgrid.ArcGridFormat.getReader(ArcGridFormat.java:157) >> at >> org.geotools.gce.arcgrid.ArcGridFormat.getReader(ArcGridFormat.java:106) >> at etclusi.tests.gt.TestArcGrid.main(TestArcGrid.java:24) >> >> The relevant code follows: >> File file = new File("d:\\bigtab\\mosaic.asc"); >> ArcGridFormat agf = new ArcGridFormat(); >> GridCoverageReader reader = agf.getReader(file); >> Have you found a similar problem?
