About
Landsat 8 Surface Temperature (Landsat 8) is part of Piksel's land surface temperature dataset series, which covers the thermal imagery archive from the US Geological Survey (USGS) Landsat satellite programme. This product is derived from the thermal infrared channel (Band 10) of the Thermal Infrared Sensor (TIRS) at 30-metre resolution. It has been validated, calibrated and adjusted for conditions in Indonesia, and is ready for monitoring urban heat islands, drought, vegetation stress and geothermal activity.
