AtoN Ranges

It would be very valuable if it would be possible to portray the nominal ranges of aids to navigation in the IWRAP model.

If the AtoN ranges are viewed and compared to traffic patterns (density plot), the effectiveness of the AtoNs at hand can be analyzed and assessed.

Note that one AtoN can have different ranges during day and night and also the range of a given AtoN can be different when viewed from different angles (sectors).
