ECRGTOC -- ECRG Table Of Contents (TOC.xml)
================================================================================

.. shortname:: ECRGTOC

.. built_in_by_default::

This is a read-only reader for ECRG (Enhanced Compressed Raster Graphic)
products, that uses the table of content file, TOC.xml, and exposes it
as a virtual dataset whose coverage is the set of ECRG frames contained
in the table of content.

The driver will report a different subdataset for each subdataset found
in the TOC.xml file. Each subdataset consists of the frames of same
product id, disk id, and with same scale.

Result of a gdalinfo on a TOC.xml file.

   Subdatasets:
     SUBDATASET_1_NAME=ECRG_TOC_ENTRY:ECRG:FalconView:1_500_K:ECRG_Sample/EPF/TOC.xml
