Kind of pre-processing:
G generalization only (faster method, but 'crossroad'
nodes might be removed).
Also the nodes from intersections may be removed.
Data will be simplified using Douglas-Peucker polyline
simplification algorithm which will ensure that the output
is not jagged.
F (or Y) full generalization + intersection detection.
Unnecessary nodes are not removed if there are
intersections (this is important for more advanced maps -
at intersections, all the intersecting roads have to have
nodes or 'find intersection' won't work).
This is very similar to 'G' with one important exception -
all intersection points of the roads are preserved too
(even if according to the simplification algorithm these
points should be reduced) - this is especially important
when we are interested in using 'find intersection'
functionality.
N no generalization and no intersection detection.
Unnecessary nodes (from the resolution point of view)
will be removed automatically.
There will be no reduction of the 'oversampled' points in
the objects - the only reduction of the points will be done
because of alignment to the same coordinates.
This option should be used if input data is prepared
separately for each layer - the data for each layer having
already been adjusted to the map author's requirements.
Used only if you explicitly provide data for all layers.
Default = F

Number of levels (layers) in the map (at least 2, not more
than 10).

Note: the last layer must always be empty, e.g. Levels=3
means that two layers only are available for map objects.
Grid size for layer # (layer 0 is the most detailed one).
