Landsat Data Continuity Mission Launched !

The latest in the series of Landsat satellites the LDCM, Landsat Data
Continuity Mission was launched on 11-2-2013 from Vandenberg Air Force Base
in California. This satellite continues the four decades old legacy of the
Earth Observation from space.   
Landsat 8 has the ability to capture a 185 km swath of Earth and is meant to
provide a regional and national scale view of our planet with a full picture
of the planet’s surface every 16 days. Among the advancements are:
    * up to 400 scenes collected per day, improving on the past 150-scene
capacity
    * a push-broom sensor to minimize moving parts and reduce failure points
    * a new short-wave infrared band to help identify clouds
    * a narrower pan-chromatic band to provide cleaner imagery at the 15m
resolution
    * new sensors to provide “ultra-blue” capacity to better study oceans
and atmospheric aerosols

Operational Land Imager (OLI):
Band # Spectral Region Wavelength Resolution 
Band 1 Visible 0.433 – 0.453 µm  30 m 
Band 2 Visible 0.450 – 0.515 µm  30 m 
Band 3 Visible 0.525 – 0.600 µm  30 m 
Band 4 Near-Infrared 0.630 – 0.680 µm  30 m 
Band 5 Near-Infrared 0.845 – 0.885 µm  30 m 
Band 6 SWIR 1 1.560 – 1.660 µm  30 m 
Band 7 SWIR 2 2.100 – 2.300 µm  30 m 
Band 8 Panchromatic 0.500 – 0.680 µm  15 m 
Band 9 Cirrus 1.360 – 1.390 µm  30 m 
 Thermal Infrared Sensor (TIRS):
Band # Spectral Region Wavelength Resolution 
Band 10 TIRS 1 10.3 – 11.3 µm 100 m 
Band 11 TIRS 2 11.5 – 12.5 µm 100 m 
 
Cartographic accuracy of 12 m or better (including compensation for terrain
effects) is expected of LDCM data products.
