I have landsat 8 OLI imagery. I want to retrieve surface temperature through this image.
You can use this interesting article to choose the information to add in modelmaker layers
ESTIMATION OF LAND SURFACE TEMPERATURE OF DINDIGUL DISTRICT USING LANDSAT 8 DATA (Rajeshwari A., Mani N. D.) 2014
you can learn from the video from the following link
https://www.youtube.com/watch?v=iN8rDNDfoWA
TIRS band data can be converted from spectral radiance to brightness temperature using the thermal constants provided in the metadata file:
the equation is at the link http://landsat.usgs.gov/Landsat8_Using_Product.php
T = At-satellite brightness temperature (K)
The constants in the equation are in the metadata (text file when you unzip the tar file). Remember: You don't need to do any atmospheric correction for the thermal band.
Lλ = 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)
Some years ago, I created a Land Surface Temperature (LST) model in ERDAS Imagine Model Maker Landsat 4, 5 TM, 7 ETM+ and 8 TIRS/OLI based on the Radiative Transfer Model (RTM) equation. Check the attached images for a screenshot. This model looks a bit messy but it works nevertheless. Alternatively, you may also want to follow a tutorial on youtube if you want to implement Landsat LST manually. However I must say that this youtube tutorial does not take into account atmospheric correction of thermal bands which is a crucial step for 'accurate' LST estimation. Let me know if you need more help.
