Hi All , I am a user of GDAL. During the appliance of GDAL, I found that GDAL doesn’t support the formats of Landsat 5, Landsat 7 and Landsat 8 data products. Therefore I wrote a format-extension for GDAL to support the formats of Landsat 5, Landsat 7 and Landsat 8 data products. I wondered whether this format-extension could be adopted by GDAL. The input data path is the metadata of Landsat, which are generally named as *_MTL.txt. Three sub-datasets are included, namely Panchromatic data, Reflective data and Thermal Infrared Sensor (TIRS) data. The format of sub-datasets are as following: LANDSAT:1:F:\Data\LandSat\LS8_O_20131022_032724_000000_128035_GEOTIFF_L4\LO81280352013295BJC00_MTL.txt Note: LANDSAT : identifier 1:index of data type (0 means Panchromatic, 1means Reflective, 2 means TIRS). The attachment is the source code that I wrote for Landsat data formats. The screenshot below is the zip file structure of Landsat 5 and 8. The zip file structure of Landsat 7 is similar to that of Landsat 5.

The zip file structure of Landsat 8 The short name of data driver that I newly added is LANDSAT. Three sub-datasets are included, namely Panchromatic data, Reflective data and TIRS data. Below is an example. The input file is a Landsat 8 data named ‘*_MTL.txt’. Fig 3 is the output information by gdalinfo. It can be seen that four sub-datasets are included. <http://osgeo-org.1560.x6.nabble.com/file/n5208438/3.jpg> Fig 3. Output information of gdalinfo.
