You may add more than two calibration points before defining the
map borders. However, 2-3 points should be sufficient to ensure a
precise map calibration.
To finish the map calibration process, click onto the disc symbol in the
icon bar, or press CTRL-S to save your changes.
For charts using the „Lambert Conical“ projection:
For charts using the „Lambert Conical“ projection method, a map
centre and two standard parallel longitudes must be indicated. These
standard parallel longitudes are usually depicted on a map right
together with the projection method itself (see sample scan below).
Unfortunately, the map centre coordinates are often missing. As a first
approach, select the middle of the whole map you are using as the
map centre, even if your file will only depict a fraction of the whole map.
Next, start adding calibrations points. For a successful calibration you
will need at least two calibration points. They should be located at
map edges, as far away from each other as possible. You need to
know the exact geographical coordinates for these points. We recommend
you to use navigation aids like VORs, NDBs or intersections. Those
navigation aids are usually listed in the national AIP (Aeronautical
Information Publication), and often they are also listed on the map itself.
To define a calibration point, right-click onto the map display where
you want the point to be placed, or select „Add Calibration Point“
from the popup-menu. A red crosshair will help you in correct placement.
By keeping the left mouse key pressed, the whole map may be moved.
Turing your mouse wheel will zoom the map in or out. For this the
cursor changes into a hand symbol. The currently selected calibration
point is displayed in green colour, other calibration points are marked red.
