1.1.7.2 Check against the Electronic Chart and the User made Chart Objects
This chapter contains details and a step by step instruction how to perform the check of the geometrically
correct route against the electronic chart, the optional raster charts or paper charts.
This verification of the planned route against charted objects must be performed before it can be made
the System Route. After each reload or any change of a route the checking must be repeated after the
relevant safety settings (Safety Contour) have been adapted to the prevailing conditions.
Preparation
1. In the menu Presentation > ENC > Depth, set the Safety Contour correctly
2. Set the type of the electronic chart against which the check is to be performed, preferable to ENC.
3. Switch on the display of the user made symbols, lines and areas in the context menu of the PPI/
Chart area under Layer > User Symbols.
4. Adjust the Range setting so that cells of the electronic vector chart or raster charts
1)
which contain
the nautically relevant information for the planned route are displayed.
5. If a vector chart is used, check whether chart cells having the appropriate navigational purpose are
present for the entire track, at least over the width corresponding to the Safety Corridor setting
or to the Track Limit contained in the route data-set:
Correctly set the display of the chart objects in the ENC that are to be displayed
• With the Set Chart Center or the Pan and Zoom Control function, step along the route to
be checked.
For those chart areas of the planned route which are not covered by suitable data cells, all nautically
relevant objects along the route must be marked by means of Own Safety Lines or Danger High-
lights.
To verify this, also the raster charts can be used if installed on your system - see step 6.
If there is no suitable raster chart available, the check must be performed manually against the
paper chart. For this purpose, the pre-planned track, including the track limits, must be entered in
the paper chart and checked on that chart visually.
6. If raster charts are used, then
2)
all nautically relevant objects along the route must be marked by
means of own Safety Lines or Danger Highlights for the entire track, at least over the width corre-
sponding to the track limit.
For this purpose, virtually sail along the route to be checked using the Set Chart Center or the Pan
and Zoom Control functions.
1)
Raster charts are not yet available in the PLATINUM system.
2)
This is prescribed for ships with DNV approval and using raster charts.
The checks mentioned in steps 5 and 6, and the editing of the own chart objects,
especially of the own safety lines and danger highlights, must be performed with
care so that the necessary level of safety can be achieved.
