Usage AIS data for analyzing ship's motion intensity

In preliminary unit of report were introduced order, structure and format of VDM code sended by the AIS VHF data link. Described the process of decoding combination of binary chains sentences describe from ITU R M. 1371.In principle unit analyse of ships intensity of movement in Gulf of Gda?sk used coded isoline on background of map as well as transverse intersection on a approach to harbour of Gdynia. Authors presented new generated and used method of processing of regular GRID net - designed to description of spatial expansion of ship intensity of movement. Authors circumscribed method of utilizations the VerticalMapper software Systemu to calculation the izoline of even ships intensity of movement, intersections of transverse, as well as principles of visualizations coded isoline on background of the map, according the author's software.
