Hi, Using ECW images on the server even as input format is not allowed at all with the new ECW 4.x SDK license. Therefore I had to convert all the ECW images used by our WMS server into geotiffs. A pretty good alternative for ECW is to create tiled geotiffs which are using internal JPEG compression inside the tiff and then create sub-sampled overviews. If the image is big it will become BigTIFF. The file size is not much bigger with the same visual quality and because of lower resolution overviews and tiled structure a proper driver is utilising such images fast at any scales.
Unfortunately at the moment OpenJUMP cannot show at all those jpeg-in-tiff images. It would be nice to get them supported. Easiest way could be to use GDAL but it woul mean lots of dlls, I fear, and we do not like them. However, I have a feeling that Geoserver can support BigTIFF without dlls with imageio. Someone who had read this fine presentation by Andrea Aime http://demo.geo-solutions.it/share/foss4g2011/gs_steroids_sgiannec_foss4g2011.pdf wrote about his experience this way: "After passing a day (and half) configuring GeoServer 2.1.2 with the following setup: - Ubuntu 10.04 - sun-java6-jdk - apache-tomcat-7.0.14 - jai-1_1_2_01-lib-linux-i586-jdk (NATIVE) - jai_imageio-1_1-lib-linux-i586-jdk.bin (NATIVE) - GDAL 1.8.1 - swig (wrappers and bindings) - imageio-ext 1.1.1 Replacing all IMAGEIO_EXT (1.0.8) jars in WEB-INF/lib folder with this: imageio-ext-gdal-bindings-1.7.jar imageio-ext-gdalframework-1.2-SNAPSHOT.jar imageio-ext-geocore-1.2-SNAPSHOT.jar imageio-ext-imagereadmt-1.2-SNAPSHOT.jar imageio-ext-jgrib1-1.2-SNAPSHOT.jar imageio-ext-jmatio-1.2-SNAPSHOT.jar imageio-ext-netcdf-core-1.2-SNAPSHOT.jar imageio-ext-streams-1.2-SNAPSHOT.jar imageio-ext-test-data-1.2-SNAPSHOT.jar imageio-ext-utilities-1.2-SNAPSHOT.jar" ..... Could it be something doable for OpenJUMP too? Somehow looks like the extension would be bigger than OpenJUMP itself. -Jukka Rahkonen- ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
