Abstract :
The authors developed an algorithm of sea traffic monitoring using JERS-1/OPS that observes a stereo pair image in one orbit. The stereo pair consisting of forward and nadir viewing has an observation time gap about 20 seconds. Measuring the displacement of moving objects on the pair image, the authors can obtain the speed vectors. Traffic information in any sea area can be obtained under the same condition through this procedure. This study focuses on a comparison of sea traffic patterns in Tokyo Bay and Osaka Bay. This work also discusses the performance of OPS data and its applicability for general speed vector measurements
