If
chart balls don’t make you feel old-fashioned enough, take a gander
at the blended cartography that first appeared in Raytech 4.0. Raster
charts, vectors, topo maps, and satellite photos can all be mixed with
variable transparency, yielding a custom view of previously static data.
You’re the mix master, and the results can be useful. Shoal soundings
that might not stand out well on a nautical chart can be highlighted by
blending in their aerial images; a C-Map vector chart can be precisely
compared to its raster equivalent.
Nobeltec
kicked the concept up another notch in Visual Navigation Suite 6.5, permitting
you to drape the blends over a 3D model of the sea bottom and coast, then
move your point of view around in that model. The feature requires a powerful
computer and an excellent screen but seems capable of delivering to the
navigator a remarkable amount of information. A good screenshot doesn’t
do this form of charting justice. Our gaming children will probably understand
this sort of visualization easily, but we need the video.
I
want to emphasize that these new forms of charting are in no way necessary.
If you’re shopping for a plotter or mapping program, you’d
be wise to focus on the more mundane, but important, issues of chart presentation
speed and user interface (see “Q&A,” this story). On the
other hand, the pace of technology cannot be ignored and may actually
be moving a lot faster than we realize. At Pop!Tech Ray Kurzweil, inventor
of voice recognition and big thinker extraordinaire, made a convincing
and startling case for an exponential rate of technological change. He
argues that innovation is at the knuckle of a steep upward curve that’s
difficult for us humans to comprehend. To put it into perspective, Kurzweil
claims that all the astounding changes we saw in the last century would
have happened in 20 years at the current rate of change. And viewed from
this current pace, uncomfortably fast as it may seem, the far-out ideas
that now sensibly seem another century away may in fact be working systems
in something like 14 years! Deduction: We ain’t seen nothin’
yet.
