Institut für Methodik der Fernerkundung International Workshop on Radiometric and Geometric Calibration Gulfport, 2 - 5 Dec. 2003 Joint ISPRS/CEOS Task Force on Radiometric and Geometric Calibration Goals: - Clarify the definitions of Earth Observing Sensor Parameters - Assist CEOS in understanding the sensor calibration/validation needs of the user community - Look at all related efforts and documents as a basis for moving forward in terms of addressing sensor parameters, calibration and validation - Prepare a document that defines sensor parameters that can be used by the user community -A preliminary joint ISPRS/CEOS report to be delivered to the ISPRS Congress in Istanbul, July 2004 Joint ISPRS/CEOS Task Force on Radiometric and Geometric Calibration

4. Institut für Methodik der Fernerkundung International Workshop on Radiometric and Geometric Calibration Gulfport, 2 - 5 Dec. 2003 Terms of Reference: 1. Collect and collate list of parameters used to describe Earth observing sensors 2. Make an analysis of these and recommend a standard list of parameters for presenting descriptions of EO satellites 3. Identify ambiguity and confusion within these terms and recommend methods and means of clarifying these issues 4. Prepare a document which sets out standard methods of describing EO- sensors 5. Communicate and consult widely with the user community. Joint ISPRS/CEOS Task Force on Radiometric and Geometric Calibration

5. Institut für Methodik der Fernerkundung International Workshop on Radiometric and Geometric Calibration Gulfport, 2 - 5 Dec. 2003 - Bring together international experts on Sensor Techniques and Calibration - Energize the recently formed Joint CEOS/ISPRS Task Force on Radiometric and Geometric Calibration and conduct the First Technical Meeting of this Group - Address JACIE experience - Explore possibilities for standardizing sensor parameters and calibration practices - Publish Peer-Reviewed Proceedings Objectives of the International Workshop on Radiometric and Geometric Calibration

6. Institut für Methodik der Fernerkundung International Workshop on Radiometric and Geometric Calibration Gulfport, 2 - 5 Dec. 2003 - Which Sensors should be considered? - Should the user compare sensors, data or products? - How is the Interaction between Sensor Parameters, Calibration Standards and Product Validation? - How does the Joint Agency Committee on Image Evaluation (JACIE) intentions fit into the interest of CEOS and ISPRS? - Can parameters be defined that are necessary for a „worldclass“ calibration test site?
