Metadata input/output

The following table lists programs that provide metadata input and output capabilities.

The standard external format for image metadata in CATALYST Professional is as an XML document contained in a text file with an 'xml' extension that is valid with respect to the schema stored in the file $PCIHOME\\etc\\PCIImageMetadata.xsd. The following is an example of such a document (metadata for bands 3 to 127 are omitted for brevity):

<?xml version="1.0"?>
<PCI-ImageMetadata xmlns="http://www.PCI-imeta.org"
                   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

METAIN reads image metadata from an XML file and writes them to a PCIDSK file. METAOUT reads image metadata from a PCIDSK file and writes them to an XML file.
