Concepts

Plugin QGIS SPT provides you for estimating Land Surface Temperature (LST) with Split-Window Algorithm (SWA) for Landsat 8.

The steps to using are fairly simple:

  1. Open the plugin QGIS SPT from within QGIS.
  2. Fill out the required value and input data band obtained from landsat 8 satellite imagery.
  3. If you have the different value, you can change the default value from advance setting.
  4. Calculate LST.

Tab Parameter

General Setting:

Parameter

  • Data Satellite is data with values obtained from the metadata used for calculate LST.
  • Output Temp. is to determine the external value of the resulting temperature.
  • Range Temp. is the average value of air temperature in the area.
  • Tot. Water Vapor is the value of total water vapor content.
  • Band Red is data from landsat 8 satellite imagery.
  • Band NIR is data from landsat 8 satellite imagery.
  • Band TIR-1 is data from landsat 8 satellite imagery.
  • Band TIR-2 is data from landsat 8 satellite imagery.
  • Save Output is to determine the external directory of the data LST.

Advance Setting:

ParameterAdv

  • At-Transmittance is the value of atmospheric transmittance.
