On this page you can set the maps storage location and the map basic data.
Cumulus supports two projections:
The first is computationally simpler and thus the preferred one in Cumulus.
The latter is more complex, so your maps will take much longer on first load
but it is more realistic.
Each map projection needs a basis from where to work.
For the Plate
Carrée projection choose a parallel close to your home base.
If the option Projection follows Home Position is activated, the
parallel is automatically set to the latitude of your Home Position in the
assumption that the Home Position is your preferred flight space. That ensures
an unskewed map display and you are not forced to set this parallel by hand.
That is the default setting.
For Lambert
projection you should select the parallels so that they are covering the area
you are flying. For example, you could choose the
parallels from your official flying map. Then you will have an equal
look like these maps. You should select the longitude from the middle
of the area you are flying. It is needed because of some technical
reasons not for the projection itself. No automatic update of projection data
is done here. You must do that always by hand. Therefore use this kind of
projection only, if you are familiar with the Lambert projection.
After changing the projection kind or the standard
parallel values Cumulus is forced to recompile your map files.
Please note that: If you don't set the projection options correctly, you will likely end up with a blue screen or a skewed map. This is especially so if you are far away from the coordinates used in the projection!
