[gdal-dev] Elevation Data Question

[Corrado, George P.]

Hello All,

Quick question, has anyone used the Java GDALtest example?  I think I might have found the elevation data I was looking for, but I'm not sure.  Below is a code snippet from the GDALtest.java class.

else if (buf_type == gdalconstConstants.GDT_Int16)
        {
            short[][] shorts = new short[bandCount][];
            for (int i = 0; i < bandCount; i++)
            {
                shorts[i] = new short[pixels];
                bands[i].asShortBuffer().get(shorts[i]);
                System.out.println("Elevation: " + shorts[i]);
            }
            imgBuffer = new DataBufferShort(shorts, pixels);


            System.out.println("Number of Banks: " + imgBuffer.getSize());

            for(int g=0; g < imgBuffer.getSize(); g++)
            {
                System.out.println("Element: " + imgBuffer.getElem(g));

            }

It looks like imgBuffer.getElem(g) is printing the elevations at each pixel.  Can anyone tell me if that's correct?

Thanks,
George

Subject: [gdal-dev] building gdal with VS10 64 bit

Hi Everyone,

Just curious has anyone successfully built gdal with VS10?  I'm not 
familiar with the link syntax like "/INCLUDE:_OGR_G_GetPointCount" but 
all of those are unresolved when linking gdal library.  Any  ideas 
appreciated.  See below for build error.

Take care,
Dave
