[gdal-dev] How to retrieve map data from Envi file?

[Chaitanya kumar CH]

Lionel,

Most the data you asked for can be obtained with various methods from the
GDALDataSet and GDALRasterBand objects. I'm not sure what you mean by units
type , but I'm sure it can be derived from them.

FYI, reference pixels are called GCPs (Ground Control Points) in GDAL. Datum
can be obtained from the projection definition. GetGeoTransform can be used
to get resolutions.

Refer to http://www.gdal.org/classGDALDataset.html and
http://gdal.org/classGDALRasterBand.html for detailed documentation.
