I've thought about offering that sort of service, but the user interface
might get complicated. I'm afraid I've only got a limited amount of time to
spend supporting non-paying stuff these days. If enough people were
interested in paying maybe $5/month for access to a professionally developed
and maintained APRS/AVL site with lots of cool features, I might consider
Seems like there's not a lot of development going on out there. I have high
hopes for OpenAPRS.net, but while it does a good job of displaying the Napa,
CA area it's really hit-or-miss when it comes to making it do anything else.
Enter N1VG-1 (in Firefox) and nothing happens. Type K6TZ-10 (in IE) and
Looks cool, but it's not quite there yet. I hope they get it working better
one of these days.
I wrote a parser service a while back that'd pipe the APRS-IS stream into an
Oracle Spatial database, and it did an excellent job with spatial queries.
You could return all stations within Santa Barbara County, stations within
.25 miles of Interstate 40 in Oklahoma and Texas only, stations more than 40
miles from a digi, or whatever. Very quick, very stable, and very scalable
- and there's absolutely no way I could afford the Oracle licensing if it
wasn't a pay service.
Maybe one of the open source (or more affordable commercial) databases can
match the spatial capabilities now, but I'd still be more comfortable
managing a high-traffic, multi-gigabyte database in Oracle than anything
And then there's the issue of maps. I'm not sure what Google's terms are
these days, but I know they've got limits. If you want to serve high
quality map data to large numbers of users, chances are you're going to be
paying someone for it.
Anyway, I'm getting off topic. Yeah, I'm working on some cool stuff. For
now a lot of it's going to be focused on features specific to my hardware -
telemetry and control, remote configuration, and so on - and I'll do what I
can to make it useful to the APRS community at large, but I'm a bit
constrained right now.
