# LST Calculator 🌡️ - QGIS Plugin

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.

## Features ✨

- **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

## Installation 🛠️

1. Download the [latest release](https://github.com/yourusername/LST_Calculator/releases) as ZIP

2. In QGIS:  

   **Plugins → Manage and Install Plugins → Install from ZIP**  

   ![Install from ZIP](https://qgis.org/en/_static/documentation/plugins_install_from_zip.png)

## Usage 🖱️

1. Click the thermal icon in the QGIS toolbar

2. Select Landsat 8 Band 10 TIFF file

3. View automatically styled LST layer

## Sample Workflow

```python

plugin = LSTCalculator(iface)

plugin.calculate_lst("/path/to/LC08_L1TP_123045_20220101_B10.TIF")

```

## Scientific Workflow 🔬

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)

## Visualization:

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

## Troubleshooting 🚑:

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

## Future Enhancements 🚀

- Automated MTL file parsing

- Batch processing support

- NDVI-based emissivity correction
