4. ENC Production Process
• Cross sections every 50m (single beam)
• dGPS provided by national system CROPOS or
reference stations every 5 km along the river
• Software tools used:
• AutoCAD / PDS 2000 for post processing
• 7C’s tools for ENC production
• DXF Converter
• ENC Designer
• ENC Optimizer
• ENC Analyzer
6. 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)
13. 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???
