  • WWJ use own image layer except LandSAT and BMNG?

    Hello World Wind Community.

    I am working on a world wind project that runs without internet access. I have my own WMS server up and running with blue marble, Landsat7,

    and SRTM data.

    1. Now I have a lot of other satellite images and want to define a layer and add them on the canvas.Is anyone can teach me how to

    configure(Specific steps),I imitate other layers add .xml file in worldwindjava\src\config\earth and add it in worldwindjava\src\config

    worldwind.layer.xml. Am I wrong?


    2.how to put 24 bit or 16 bit in tiles? Use FWtools dstile.exe? First I transform them in 8 bit through Envi ,and then dstile tile --lztsd 1.0 --wwcache --overviews images L0.tif,gray image is well.why hsi and vlc image not good?


    Thank you

          Let me clarify what I think about dstile, globalMapper , or directly with FWTools.

          Basically you are just breaking a file into small pieces and then combining what is necessary for the overviews. It does nothing to change the number of bits for the color. What you feed in is what you will end up in jpg, ping or whatever. So turboHyperspectral images,Visible light image is something you can play with but that is not specific to WWJ and whether any of that will work is just a guess until you try it. Are you a gamer programmer where some of this may be viable. ??? You did not mention anything about removing the leading (00)s with dstile. Someone modified dstile to remove the leading 00s.

          There is a lot of data in this forum to help with tiling. Learn that before getting into (turboHyperspectral, Visible light images) or whatever.

          If you come up with something special please post as someone may be interested.

              Glad to help. do all of the Hyperspectral processing of your images first then tile them.

              If you just tile the highest resolution level without the overviews You are just breaking your input image to the tiler into smaller pieces, there is no magic involved. A tiler has nothing to do with 'Hyperspectral processing'
