Abstract

Marine airborne multispectrum scanner MAMS onboard the China marine surveillance plane can be used to survey marine environment resources and disaster and provide the technical support for highfrequency highefficiency and highresolution remote sensing monitoring for the coastal management MAMS did not have the IMU/POS equipment so it brought severe challenge for the geometry correction One airborne geometry correction method is introduced for marine multispectrum data without the attitude information First it is the coarse geometry correction which simulates the roll angle and pitch angle of plane according to the ideal flying model the second step is the precise geometry correction by using the SPOT orthogonal projected data as the reference of registration based on maximization of alignment metric method With the validation relative error of coarse correction is 8142 m compared with SPOT data and 113 m for precise correction This method provides the high precision localization information for the oceanic remote sensing and application and establishes the foundation for monitoring the marine resource and environmentFoundation item The Scientific Research Fund of the Second Institute of Oceanography State Oceanic Administration of China under contract No JG1016 Special Funds for Scientific Research on Public Cause of China from Ministry of Finance under contract No 200805028
