I've added support for a bunch more APRS data. Please check it out and
let me know how it goes.
Any ideas where else I could announce this to get some knowledgable
people to look at? Not places like eHam.com... I've posted it on
#hamradio on irc.freenode.net...
I applied to make this a sourceforge.net project, haven't heard back
from SF yet though.
NAME
Ham::APRS::Parser - Perl module for parsing APRS packets into a
consistant and easy to work with format
SYNOPSIS
use Ham::APRS::Parser;
my $aprsPacket =
parseAPRSPacket("EA1EKE-8>TR3UTW,EC1H-12,EA1A-3*,qAo,EA1URO-10:`|@+
,>/>"9f}");
while( my ($k, $v) = each %$aprsPacket ) {
print "key: $k, value: $v\n";
}
DESCRIPTION
Insert plaintext aprs packets from APRS-IS, get back a reference to a
hash containing the APRS data in a consistant and easy to process
format.
The above code will yield the following hash:
%$aprsPacket = {
'AMBIGUITY' => 0,
'COMMENT' => '"9f',
'COURSE' => 234,
'FROM' => 'EA1EKE-8',
'LAT' => '42.5911666666667',
'LON' => '-6.6025',
'MICE_CURRENTNESS' => 'CURRENT',
'MICE_MSG' => 'En Route',
'PATH' => 'EC1H-12,EA1A-3*,qAo,EA1URO-10',
'SPEED' => '75.932',
'TO' => 'TR3UTW'
};
Be careful, because Mic-E packets use the TO field as data, not a real
callsign. Also Mic-E packets may contain non-printing chars, although
the output should be 100% printable.
The module tries to be fast by using dispatch tables and not using
regular expressions unecessarily.
I wrote this module because I wanted to translate APRS packets into
KML files for displaying on Google Earth. Unfortunately Google Earth
can't handle the tens (or hundreds) of thousands of APRS stations all
at once. I will keep working on ways to get around this.
Other neat applications might be an advanced, highly intellegent
digipeater. Or a free open source findu.com replacement using Google
Maps.
Currently the module should mostly reliably return these fields from
position reports, Mic-E position reports, and compressed position
reports:
* TIME_FORMAT
* TIME
* GPS_FIX
* NMEA_SRC
* COMP_ORIG
* ALTITUDE
* COURSE
* LAT
* LON
* SYMBOL
* MESSAGING
* MICE_MSG
* MICE_CURRENTNESS
* MICE_DEVICE
* FROM
* PATH
* TO
* COMMENT
* AMBIGUITY
* SPEED
* RANGE
...
