Datasets in FAST format represented by several files: one or more administrative headers and one or more files with actual image data in raw format. Administrative files contains different information about scene parameters including filenames of images. You can read files with administrative headers with any text viewer/editor, it is just plain ASCII text.
This driver wants administrative file for input. Filenames of images will be extracted and data will be imported, every file will be interpreted as band.
FAST-L7A consists form several files: big ones with image data and three small files with administrative information. You should give to driver one of the administrative files:
From the `` Level 1 Product Output Files Data Format Control Book'':
The file naming convention for the FAST-L7A product files is
L7fppprrr_rrrYYYYMMDD_AAA.FST
where
L7 = Landsat 7 mission
f = ETM+ format (1 or 2) (data not pertaining to a specific format defaults to 1)
ppp = starting path of the product
rrr_rrr = starting and ending rows of the product
YYYYMMDD = acquisition date of the image
AAA = file type:
HPN = panchromatic band header file
HRF = VNIR/ SWIR bands header file
HTM = thermal bands header file
B10 = band 1
B20 = band 2
B30 = band 3
B40 = band 4
B50 = band 5
B61 = band 6L
B62 = band 6H
B70 = band 7
B80 = band 8
FST = FAST file extension
So you should give to driver one of the L7fppprrr_rrrYYYYMMDD_HPN.FST, L7fppprrr_rrrYYYYMMDD_HRF.FST or L7fppprrr_rrrYYYYMMDD_HTM.FST files.
