Ciao Gary,I downloaded you geotiff and I simply opened it up in a simple test app I built some time ago using MapPane. It seems to woek just fine but there are a couple of things to say:
1>I have attached a java file with my stupid sample app. You need to put all the needed jars in the classpath, main, referencing, coverage, geotiff, image, etc...
I usually start it this way:
program arguments: path=ath_to_my_geotiff VM arguments: -Xmx200M -Dorg.geotools.test.geotiff=true
if yu set -Dorg.geotools.test.geotiff=false the test ap will try to force to open the image as a world image which will fail in your case since no prj was is present, otherwise the app will use the geotiff will use the geotiff reader and everyting will be fine.
2>Your tiff fis an indexed tiff hence it won't work on 2.3.0. I have added support for images with palette at the beginning of Jan, after 2.3.0 was release. You can download a snapshot of 2.3.1 here http://www.geo-solutions.it/gt2_nightly/ along with the relevant source code. This is the version I am using
3>In case you want to open the image as a world file, please provide a prj file.
4>Performances are good, but if you want more you need to add overviews to you geotiff and also to tile it.
Let me know how it goes. Simone. ------------------------------------------------------- Eng.

To: <[email protected]> Sent: Wednesday, February 28, 2007 4:32 PM Subject: [Geotools-gt2-users] Problem plotting GeoTiff imageI am back to working with GeoTools after several months away due to commitments to other projects. When I left off on my GeoTools work (rather reluctantly I might add, since it GeoTools is pretty interesting stuff), I was stuck on a problem with GeoTiff files and hoping that it would be fixed by the then new release 2.3.0 Unfortunately, I'm now using 2.3.0, I'm still having no luck, and am beginning to think that there is a bug in the GeoTiff implementation.
Basically, I took the MapViewer.java demo and added some lines of code (shown below) as a the "loadTiff" method to attempt to add the GeoTiff to the MapViewer picture (loadTiff is called after the existing MapViewer "load" method). This code has worked for some other GeoTiff products, but is still not working for the GeoTiff in which I am most interested. When I run the MapViewer demo, I often get ProjectionExceptions and IllegalArgumentExceptions. Some of them appear to relate to the proximity of the map to the North Pole (I am using a global scale Shape file). But even when I zoom in to the area of interest for the GeoTiff, GeoTools doesn't always throw an exception but still declines to produce an image
The GeoTiff is in a Lambert Conic Conformal projection, but the MapViewer is set to use good old CRS "EPSG:4326"
Can anyone offer me guidance? Gary ----------------------------------------------------------------- Using GeoTools 2.3.0 The source data for the GeoTiffs is available at http://avn.faa.gov/index.asp?xml=naco/catalog/charts/digital/Raster_Sectional_Sample/Raster ----------------------------------------------------------------- The code added to the "loadFiff" method isFile tiffFile = new File("C:/Downloads/FaaSectionalMap/sample.tif");

StyleBuilder sb = new StyleBuilder();
RasterSymbolizer rsDem = sb.createRasterSymbolizer();
org.geotools.styling.Style demStyle = sb.createStyle(rsDem);
MapContext context = mp.getContext();
context.addLayer(rdr, demStyle);
