Driver built-in by default

This driver is built-in by default

GDAL supports the Envisat product format for read access. All sample types are supported. Files with two matching measurement datasets (MDS) are represented as having two bands. Currently all ASAR Level 1 and above products, and some MERIS and AATSR products are supported.

The control points of the GEOLOCATION GRID ADS dataset are read if available, generally giving a good coverage of the dataset. The GCPs are in WGS84.

Virtually all key/value pairs from the MPH and SPH (primary and secondary headers) are copied through as dataset level metadata.

ASAR and MERIS parameters contained in the ADS and GADS records (excluded geolocation ones) can be retrieved as key/value pairs using the “RECORDS” metadata domain.

NOTE: Implemented as `gdal/frmts/envisat/envisatdataset.cpp`.
