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
