AutoChart has been modified to allow the user to define and use a Custom Format ini file for Sub Bottom Profiler (SBP) file types. The SBP Custom ini files must be stored in the \SubBottom sub-folder of the AutoChart Formats support folder (e.g. C:\AutoChart\Formats\SubBottom) and follow the following conventions:

Positions must be stored in fields named 'Easting' and 'Northing'

Horizon depths must be relative to the seabed and stored in a field named 'Depth'.

Nodes and Tag names must be defined in a field called 'Node' and a field called  'TagName'. Node values should be 'S' (for start of horizon), 'I' (for intermediate points on the horizon) and 'E' (for End of Horizon). Point values can be denoted by use of an 'S' or 'E' node value, or by any other value (e.g. 'P') out with a normal horizon definition.

Optionally a 'Description' field can be used in the ini file and then the values contained by this field will be added to the points and horizon vertices.

As explained in FR672, Header lines can be skipped and unit conversion can be performed by setting these options in the ini file definition.

Example SBP ini file:

#AutoChartName,ColumnPosition

#Valid AutoChartName values are Easting, Northing, Depth, TagName, Node, Description.

#Easting, Northing, Depth, TagName and Node must be present.

#To use tab delimiter you can use a tab character or for the avoidance of doubt when perusing this file "\t"

#Delimeter,"\t"

#HeaderLines,3

TagName,1

Node,2

Easting,3

Northing,4

Depth,5

Description,6
