DU Yang-wen · Geomatics & Spatial Information Technology · 2006
Remotely controlling the buoy's work state and spatial location by a monitoring information system is an efficient strategy to improve the management level and to guarantee the waterway safety in the field of inland waterway management.In this kind of monitoring system the electronic map plays the role of location background and spatial operation tools of analysis,query and remotely representation of spatial data.Based on the experiences of a real system development,this paper investigates some key technologies including the extension and application of S57/S52 standard data from maritime field to inland waterway,the organization of spatial data,the real-time representation of buoy change in the electronic map and post-analysis.
