The Make boundary polygon part:
Options:
- Soundings
- Seafloor
Select to create the boundary from either Soundings or Seafloor.
Options:
- From Soundings: Create boundary and/or holes polygons from the points data.
- From Seafloor: Create boundary and/or holes polygons from the Seafloor surface.
The Buffer part
...
Buffer distance (m): This parameter is valid for the option Soundings. Around each point a circle with radius set to the buffer distance is created. The boundary and holes polygons are created by merging the small circles into one or more larger polygons.
The Boundary part
Boundary: Check (set) this option to generate the result Boundary polygon.
Options:
- Keep all boundary polygons: Do not filter away any polygon.
- Remove small boundary polygons: Use filter to remove "noisy" polygons from the data. Specify number of Buffer circles for the size if the polygons. If the option is to create boundary from the Seafloor, the size of one Grid cell is used as the smallest unit.
The Holes part
Holes: Check (set) this option to generate the result Holes polygon.
Options:
- Keep all holes polygons: Do not filter away any polygon.
- Remove small holes polygons: Use filter to remove "noisy" polygons from the data. Specify number of Buffer circles for the size if the polygons. If the option is to create holes from the Seafloor, the size of one Grid cell is used as the smallest unit.
The Chart Name part
Select from the list which charts to apply.
