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. |
