I am currently using GIS for a study and would like to know if retrieving Band 10 and multiplying it with the scaling factor (0.00341802 + 149.0) is enough to get the LST? Thanks!
Google Earth Engine's (GEE) table (https://developers.google.com/earth-engine/datasets/catalog/LANDSAT_LC08_C02_T1_L2#bands) might be useful to you. The scaling factors you mentioned are correct. But keep in mind that your Land Surface Temperature will be measured in Kelvin.
