Landsat
Data Formats
|
Landsat TM and ETM+ data is available in the following formats:
- CEOS
- FAST
- HDF
- GeoTIFF
- NLAPS
The CEOS, FAST, HDF and NLAPS files are all BSQ (Band Sequential), with one file for each band. Landsat 5 MSS data from ESA comes in CEOS format, BIL (Band Interleaved), with one file for all bands.
In the CEOS, FAST, HDF and NLAPS formats the images are simply 8-bit integers (the CEOS file contains a 100 byte header). The differences are in the ancillary files that accompany the data: CEOS files have much more information, but it is harder to read (click here to download software for reading this information).
FAST, HDF and NLAPS files set out the key information more clearly. GeoTIFF (Geographic Tagged Image File Format) has only the image files in a georeferenced TIFF. This format should be ordered only for Level 1G System Corrected products with map orientation, ready to use for GIS applications.radiometry.
