  1. Hi,

    Try to read the IMG as UInt16 LSB type. This may solve your problem. 
    I haven't try the IMG data with MATLAB, but I could read them with c# codes. Below is some hint when I read the IMG with C#.

    - read the img as binary
    - convert the binary data to the right format

                int numPixels = nColumns * nRows * nBands;
                var img = new UInt16[numPixels];

                Byte[] myBytesReordered = new Byte[2];
                for (int i = 0; i < numPixels; i++) 
                {
                    int byteImgId = i * 2;
                    myBytesReordered[0] = data[byteImgId];
                    myBytesReordered[1] = data[byteImgId + 1];
                    img = BitConverter.ToUInt16(myBytesReordered, 0);
               }

    Attached is the screen capture of my result with 2% linear stretch. Please let me know if you need more help. Thanks,
    June

  14. Do you mean the black pixels along the edge of the image, which represent no data? If that is the "black pixels" you want to clean, in ArcGIS, when you overlain the CRISM output onto a DTM,  right click the image, and choose properties. Below is the instruction to remove the background area of a raster layer using the Unique Values renderer in ArcMap. Arcscene has similar function to set the background color as transparent. Or you can google an example. I cannot use ArcGIS desktop these days due to a university license issue. People are still working on that. If you still have problem, I can send you a pic example as soon as I can access my ArcGIS desktop again. Thanks,

  15. I am not quite understand your question. Do you like to know how to give a 3D view? I saw your overlain of the CRISM onto a CTX. If you overlain all the images onto a DTM, and change the terrain exaggeration factors, you will see something like above figures from different points of views.

    HiRiSE DTM has much higher resolution than the DTMs from HRSC and MOLA.

    Map resolution for a HiRISE image is about 25cm/pixel, and the HiRISE DTM is about 1m/pixel.
    HRSC DTMs have various resolution from 50m/pixel to 400m/pixel. Most of the products are at the resolution of ~50m/pixel, 75m/pixel, and 100m/pixel.
    MOLA DTM is about 500m/pixel.
    CTX image is about 6m/pixel. And FRT CRISM data are about 18m/pixel.

    Depending on your needs, the higher resolution of a DTM, the more detailed features the terrain can represent.
