How to use C-Map charts
This section includes a short summary of the various tools used to move within
the C-Map charts. For a more detailed review, please refer to the chart selection section.
Use the hand tool
to move the chart : click upon the chart and have it slide while pressing on
the left button of the mouse : the chart will move simultaneously with the
hand.
To have the information dialogue relating to the displayed chart appear,
click twice upon the chart with the mouse left button. The information dialogue
will inform you about the chart geodesy, about creation dates, etc.
In order to change the scale, select the magnifying tool
and click within the chart onto the desired place. Then select a scale in
the available scales list. Some scales appear with a mark : these are the
scales for which the chart will be of better quality. If you select a scale without
a mark, the chart will appear in overzoom (the chart will be ãenlargedä).
