The Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) on board of the Advanced Land Observing Satellite (ALOS) was launched for earth observation and there are more than 12 million scenes of archives including coastal areas during period of five years. Nowadays, the number of AIS (Automatic Identification System)-equipped ships is increasing for maritime safety and monitoring vessel traffic. The purpose of this paper is to acquire the knowledge about kinetic analysis of vessel traffic by satellite images with simultaneous acquisition of AIS data. We extracted vessel information from ALOS images with AIS data by using GIS (Geographic Information System) in the Straits of Malacca on 4th May 2010. It should be noted that this process would enable to classify various length vessels with AIS-equipped or AIS-unequipped. Then, Speed and Course of each vessel was obtained from observation time difference between two satellite images. The comparison between the information of each vessel from satellite images and AIS data (SOG:Speed over ground and COG:Course over ground) as actual measurement value show a quite good agreement.
