Storm Cell Information and Tracking (SCIT) indicators when new radar data is available.
azimuth – The angle of horizontal deviation, measured clockwise in degrees, from one point on a
map to another.
base view – A saved view that acts as a starting point for a zoom, pan, or time-lapse operation.
bend – The curve in a squall projection that indicates the shape of the storm front.
circle projection – A type of storm projection that indicates the communities within a storm and
their distance, in miles, from the storm’s center.
creating a storm track – The action of clicking and dragging to create a fan, circle, or squall
projection.
cut off range – A range that defines when a parameter appears on a view. Any view with a view
range at or below that cut-off range shows the parameter; any view with a view range larger than
the cut-off range will not show the parameter.
database – A collection of associated data.
dynamic sizing – An option available only for Street Spotter text. This option, which is available
when you select Setup Street Spotter, makes the system automatically select a font size that
fits the length of the line when labeling a street in Street Spotter mode. It also proportionally
changes the text size when you zoom in or out of a view.
extrusion – A text option that places a shadow behind each letter at a user-defined angle. This
option is available when you select Setup Fonts commands.
fan projection – A fan-shaped storm projection used to track a single storm cell. Select Storm >
Add > Fan to create a fan projection.
fanout – This parameter determines the degree to which a fan-type storm track’s border expands
from the base to the end, to account for the possibility of the storm not moving in a straight line.
The value is set on the Storm Track panel and has a maximum width of 40 degrees.
frames – These are extra images added automatically by SEQUENCER when creating zooms,
pans, and time lapses. The extra images provide a smooth transition between the starting and
ending view.
