Integration of Spatial Data from External Sensors in the Mobile Navigation System for Inland Shipping

The popularity of mobile devices is growing also in the field of water navigation. One of the disadvantages of them however is lack of hardware possibilities for direct connection of external sensors. The paper provides discussion on the possibilities of external sensors using in mobile navigation system for inland shipping. The analysis of data and sensors availability in this filed is followed with data model definition. Then various possibilities of integration of spatial data in the system are presented, including typical for GIS, geoinformatic web services approach.
