Past/current state production lines Rijkswaterstaat

• 2 Production lines• Started 10-15 years ago (2 different regions of RWS, different goal)• Both production lines based on customized software, which will no be

supported in the future• Changes of organisation at Rijkswaterstaat• Data quality not always good and verifiable

Rijkswaterstaat7 ENC production at RijkswaterstaatRWS UNCLASS

Difference between two production lines

• First production line based on: – Re-use of Rijkswaterstaat datasources to

make a IENC – For all inland waterways (IENC)

• Second production line based on:– Manually maintained nautical database– Used for Zeeland (Antwerpen), Amsterdam,

Eems:• IENC• Port ENC (used by pilots, traffic centres)• To compute time windows for ships

– Including measured depths/surveys (10 cm isolines)

– Over 700 surveys each year

Transition

• Starting point (principles)– COTS (standard) software– Comply with Inland ECDIS 2.3 (909/2013)– Re-use of datasources– Smooth transition (priority for production)– Able to add as built situation in nautical database– Extra: Based on (ESRI) architecture port of Rotterdam
