Inheritance diagram for L7A_Fast:

Detailed Description

This is an ImageFormat implementation of the multi file Landsat 7A Geotiff.

This tests the standard naming convention of this format and loads all available bands within the directory of the file that was chosen for opening. This uses a GDALFrmt for every loaded band and forwards its information and I/O.

History:: 2006-01-09 dls - Altered open function to pull fill in more metadata from image in ImageInf structure
