GEOTIFF pixel interpretation
I am just starting to learn about reading in GEOTIFF files. I am using the BEAM API. I had a question regarding the GEOTIFF format. I have a land cover GEOTIFF file where I have unsigned 8 bit ints for storing the land cover type.
When I print out the values of the pixels I get values for the land cover types(which are ranging from 10 to 100) as well numbers ranging from 0 to 255. How do I know what byte refers to the land cover type and what byte refers to the color palette ? I need a Pixel interpretation of the GEOTIFF file.

I presume I would have to know about byte ordering and TIFF header before I get to the actual data. Any idea where I can get this level of information ?
