Symbol Behind Sounding

The BKSYM keyword inserts a symbol behind a sounding.

1. In the master file, add a new record for soundings with background.

It should look something like this:

The BKSYM keyword in the D subrecord tells CARIS to use a symbol with feature code CIRCLEFL. The CIRCLEFL feature code must exist in the master file.

If this is a filled symbol, it will be drawn in the default colour. To change the colour of the symbol:

2. In the master file, add a composite symbol which sets the colour for the background symbol.

The record should look something like this.

Note that green is not the colour green but is a feature code which is referenced in the colour map.

This record tells CARIS that the symbol with feature code SBKCOL is the same as feature code CIRCLEFL but with a specific colour.

3. Modify the original record so that the BKSYM keyword references this new feature code.

4. Rebuild the symbol file using the Rebuild Symbol File tool.
