Release Date: Dec XX, 2015
This application produces Land Surface Temperature products for Landsats 5, and 7.
See the PLACE HOLDER product guide for information about the Land Surface Temeprature products.
- Initial implementation
- ESPA raw binary libraries, tools, and it's dependencies. Found here
- Python 2.7+ and Scipy/Numpy/GDAL
- GDAL 1.11.1
- The command line tools are utilized for some of the processing steps.

- Clone the repository and replace the defaulted version(master) with this version of the software
git clone https://github.com/USGS-EROS/espa-land-surface-temperature.git
cd espa-land-surface-temperature
git checkout version_<version>
- Build and install the application specific software
make
make install
See land_surface_temperature.py --help
for command line details.
- PATH - May need to be updated to include the following

export ASTER_GED_SERVER_PATH="/ASTT/AG100.003/2000.01.01/"
This version of the Land Surface Temperature application requires the input products to be in the ESPA internal file format.
The following input data are required to generate the spectral indicies products:
- Top of Atmosphere Reflectance (TOA)
- TOA products can be generated using the LEDAPS or L8_SR software found in our espa-surface-reflectance project. Or through our ondemand processing system ESPA, be sure to select the ENVI output format.
- Elevation
- Elevation data is expected to be in the same projection and image dimensions as the TOA products and in the ENVI file format. The filename is also expected be
<sceneid>_dem.img
: where sceneid is the Landsat Scene ID of the data being processed.
- Elevation data is expected to be in the same projection and image dimensions as the TOA products and in the ENVI file format. The filename is also expected be
- ASTER GED
- ASTER GED data can be found here. However it will automatically be retrieved for you as needed and cleaned up.
- North American Regional Reanalysis (NARR)
- NARR data, it would be best to utilize the
lst_aux_data
software provided in this project to download and build your own archive for the dates you require.
- NARR data, it would be best to utilize the
After compiling the espa-product-formatter libraries and tools, the convert_espa_to_gtif
and convert_espa_to_hdf
command-line tools can be used to convert the ESPA internal file format to HDF or GeoTIFF. Otherwise the data will remain in the ESPA internal file format, which includes each band in the ENVI file format (i.e. raw binary file with associated ENVI header file) and an overall XML metadata file.
