Interpret and apply a wide variety of cartographic data using ESRI ArcPro and ArcMap in order to maintain the national navigational database used to produce charts. Compile cartographic information into the database using established charting policies, standards, and procedures as documented in the Nautical Charting Manual. Research historical information and charting records to resolve discrepancies between existing charted information and new data. Use knowledge of map projections and datums to process and transform incoming mapping data to a form appropriate for use in nautical charts. Use validation software and procedures to ensure that the charts conform to applicable international standards. Compiled data from approximately 130 sources to verify and update over 300 nautical charts and ensure safe navigation of mariners.
