The sonar XYZ data is rendered using various CAD programs. For small areas the collected sonar data is dense enough to create a 1/4 metre mesh, this helps us illustrate areas such as:

• Any debris in the ships berth
• Payout line for dredging
• Slope values
• Underming of caissons
• Areas under pile docks
• Bottom trends
• Monitoring of siltation
• Comparisons with the as built drawings
• Areas of scour
• Overlay repeat surveys for historical comparisons
