KEALib provides an implementation of the GDAL data model. The format
supports raster attribute tables, image pyramids, meta-data and in-built
statistics while also handling very large files and compression throughout.

Based on the HDF5 standard, it also provides a base from which other
formats can be derived and is a good choice for long term data archiving.
An independent software library (libkea) provides complete access to the
KEA image format and a GDAL driver allowing KEA images to be used from any
GDAL supported software.
