Please dont let my comments block your plans, but please
consider that using ICONs and drawing things on maps may 
have a nice future application for conveying traffic information 
to APRS users, but -currently- less than 3% of APRS mobiles 
are actually using a PC display whereas 85% of all APRS 
mobiles that "receive and display" APRS data while mobile 
use the D7 or D700.

That is why the present APRS Traffic monitoring system
was designed very specifically for optimizing the display
of this informaotn on the front panel of this radio and its
head's up display under the nose of the driver.

Investing a lot of time in making a slick display for PC's
is laudable, but please also make sure that it displays
on the D7 and D700 radios too where almost all the
drivers are watching...

Again, dont take these comments as intended to stiffle
innovation, but just dont overlook the obvious immediate
useage...

de Wb4APR, Bob

Use APRS area objects (line objects are part of that), or else use
this:
