OLI operates alongside TIRS (Thermal Infrared Sensor) on board the LDCM. The build and design of OLI differs from previous generations of instruments, while still maintaining data continuity with archived Landsat data from the last 40 years by keeping the same spectral and spatial resolutions of previous instruments.
