plotting all the navaids current positions, obstructions long before the

It's difficult to envision a time when all navaids have AIS
transponders installed, don't think it will ever happen except for the
very biggest/most important. Look at how many unlighted navaids we
have now, which is very low tech/low expense by comparison.

If you have a good quality color radar with all the bells and
whistles, it is not that difficult to get the information you need.
My Furuno for instance has the ability to overlay the chart and radar
image on top of each other, and keep it aligned with your heading.
