Driver short name

ECRGTOC

Driver built-in by default

This driver is 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
      SUBDATASET_1_DESC=Product ECRG, Disk FalconView, Scale 1:500 K
