While the spectral and spatial resolution of OLI's channels were kept the same as prior instruments in order to maintain data continuity with the entire
Landsat archive, two spectral bands (the first a blue visible channel and the second an infrared channel) were added. These bands were designated as

OLI aids the
Landsat-8 mission in the imaging of Earth's surface and the collection of moderate resolution data that is used to monitor changing trends on the surface and evaluate how land usage changes over time. The images and data that OLI has helped collect have practical applications today in

OLI is a pushbroom sensor that operates in the visible (VIS) and short wave infrared (SWIR) spectral regions. It has a swath width of 185-kilometer (115 mi), which means it can image the entire Earth over a repeating cycle of 16 days. The OLI has nine spectral bands, including a panchromatic
80:
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

OLI has several different applications due to the many different bands. Band 1 is helpful in imaging shallow water resources and tracking aerosols. Bands 2, 3, and 4 are in the
