Metadata refers to a specific image in a PCIDSK file. All images and associated metadata are considered image data sets. Channels, other than those containing image data set bands, can exist in a PCIDSK file. Metadata is not associated with ancillary raster data or raster maps produced from image analysis.
Focus supports image metadata to accommodate hyperspectral processing and analysis with PCIDSK files. The metadata must be in Extensible Markup Language (XML) format in a text file. By running the METAIN algorithm (available in Algorithm Librarian) with the text file as input, the metadata is written to a metadata segment in the PCIDSK file that contains the associated image data. Existing metadata is overwritten. The METAOUT algorithm reads the metadata from a segment in the PCIDSK file and write it to an XML file.
The required format of an image metadata XML file is specified by the XML schema stored in the PCIImageMetadata.xsd file in the $PCIHOME/etc folder of your CATALYST Professional installation.
