• Conclusion

Sample ENC

• Test stretch defined rkm 1320 to rkm 1305

• Rocky bottom of the river bed

• Training works planned

• Single beam 1320-1305

• Multi beam 1310-1308 (measurements ongoing)

Agenda:

• ENC production process

• Sample ENC

• Conclusion

Conclusion

• Depth information definitely brings added value to the ENCs

• Single beam vs. Multi beam

• Multi beam definitely recommended for the critical sections

• Single beam usable for the non critical sections

• Full coverage with the depth data???

Thank You!
