Sometime, remote sensing data are not contained in a single file. For example it is common to find sample values in a raw binary file (a flat matrix), and metadata informations in a separated text file. There is a wide variety of formats for such text file, and supporting them is not always straightforward. {@link org.geotools.coverage.io.MetadataBuilder} is a helper class for making easier to parse the header file. The content (the actual pixel values) can be parsed using the {@link org.geotools.image.io} package.
