# rLandsat8 - an R interface to Landsat8

TIRS band data can be converted from spectral radiance to brightness temperature using the thermal constants provided in the metadata file:

where:

$$T$$ = At-satellite brightness temperature (K)

$${ L\lambda }$$ = TOA spectral radiance (Watts/( m2 srad μm))

$$K1$$ = Band-specific thermal conversion constant from the metadata (K1_CONSTANT_BAND_x, where x is the band number, 10 or 11)

$$K2$$ = Band-specific thermal conversion constant from the metadata (K2_CONSTANT_BAND_x, where x is the band number, 10 or 11)

### Example
