T0512 - MAPPING AND GIS ANALYSIS SOFTWARE

Trinity House Navigation Directorate currently use mapping and GIS analysis software to process hydrographic surveys and plot contours, plot and view aids to navigation, analyse maritime AIS data for varying levels of risk assessment. The current system utilises Admiralty ARC charts and AIS data provided by the MCA and processed externally into the formats required by TH. Our charts are updated weekly from the UKHO website and the chart supplier contract is not within the scope of this exercise. We require a system able to view Admiralty Raster Charts provided by our chart supplier and stored on an internal server. The charts are used to view the latest maritime data available from UKHO for hydrographic and aid to navigation assessment.
