  2. Introduction • Radiometric calibration of satellite sensors is indispensable, because satellite sensors are degraded as time passes. • Cross calibration between different satellite sensors is one of various radiometric calibration methods.

  3. TERRA/MODIS TERRA/ASTER FORMOSAT-2/RSI Cross Calibration

  4. Cross Calibration for FORMOSAT2/RSI • ASTER has been radiometrically calibrated by several methods since TERRA was launched. • We just started cross calibration plan for FORMOSAT-2/RSI using TERRA/ASTER. • Data search is the first step for cross calibration, and satellite imagery of same location with few time lags are required.

  5. Data Search • GEO Grid has an integrated data search system which can find satellite imagery of a particular location from federated databases (TERRA/ASTER, TERRA/MODIS, and FORMOSAT-2/RSI). • Firstly, we started searching imagery of FORMOSAT-2/RSI and TERRA/ASTER on the test sites using for radiometric calibration in the world.

  8. Future Works • To find more satellite imagery is desired for cross calibration between FORMOSAT-2/RSI and TERRA/ASTER. • We are planning to making cross calibration system of multiple satellite sensors, which will be an application using GEO Grid.
