A radius table sets the minimum radius between soundings for various depth ranges. Each depth range will have its own radius value.
The sounding radius table is a text file containing three columns:
• minimum depth of the range
• maximum depth of the range
• radius value for the depth range.
For example, using the example radius table below, 8m soundings would be a minimum of 1mm apart at map scale, while 80m soundings be 10mm apart.
Min depth | Max depth | Radius value for range |
