Appendix D. Marker Files
Seanet Pro includes the facility to lay a series of markers to label and track objects,
points of interest and way positions. These markers can be saved to file for the purpose
to re-load at a later date, to form part of a report or for use with the Sonar Image
Tiler program.
There are two formats of marker file:
1. A full, comma separated file format with the filename extension
.mrk
2. A shortened, comma separated format with the filename extension
.csv
