A QGIS plugin for calculating Land Surface Temperature (LST) from Landsat 8 TIRS Band 10 data. Designed for remote sensing analysis with an intuitive workflow and thermal visualization.

• TOA Radiance Calculation using metadata constants
• Brightness Temperature Conversion to Celsius
• Thermal Visualization with custom color ramps
• QGIS 3.0+ Compatibility
• Simple GUI integration with toolbar icon

1. Download the latest release as ZIP
2. In QGIS:
   Plugins → Manage and Install Plugins → Install from ZIP
   

1. Click the thermal icon in the QGIS toolbar
2. Select Landsat 8 Band 10 TIFF file
3. View automatically styled LST layer

plugin = LSTCalculator(iface)
plugin.calculate_lst("/path/to/LC08_L1TP_123045_20220101_B10.TIF")

TOA Radiance: Lλ = ML * B10 + AL

(ML/AL from MTL file)

Brightness Temperature: BT (°C) = (K2 / ln(K1/Lλ + 1)) - 273.15

(K1=774.89, K2=1321.08)

Thermal color ramp from 20°C (blue) to 70°C (red)

Error Solution

• GDAL Error 4 Verify input file is valid GeoTIFF

• Missing Layers Use Landsat 8 Collection 2 data

• Incorrect Values Check MTL file constants

• Automated MTL file parsing

• Batch processing support

• NDVI-based emissivity correction

• Landsat 8 Data Users Handbook

• QGIS Plugin Development Guide
