What is APRS? Where to get APRS Featured APRS app: Xastir Westchester County Maps APRS digipeaters covering Westchester County) APRS on the Internet A first: the MS Walk on 4/20/97 How the maps are made
Applications of APRS include vehicle tracking during public service events, use in the National Weather Service SKYWARN program, and just chatting with others (via keyboard).
To learn more about APRS, start at: http://aprs.org
Most of currently available version of APRS software are shareware programs that you can use for free but that encourage you to register (pay the shareware fee to the authors). Unregistered versions nag you each time you start them to register, primarily by preventing you from saving your configuration. This means you have to reenter your callsign and two or three other pieces of information each time you start the program. This is called Nagware.
Note that the various APRS versions are written by different people so if you are considering one or the other for your PC, you should try them both for a while first and decide which you want to spend your money on (or spend no money and use Xastir:-).
If you are into Linux (or want to run Cygwin under Windows), check out Xastir. Xastir is totally free (GPL) software and is perhaps the most sophisticated version, supporting a variety of local on-disk and Internet map sources and other features, including:
You can find pre-packaged Xastir and pre-req software here for Red Hat Linux. But if the files look a little out of date, please check the official Xastir site for updates.
A collection of shapefile maps for Xastir is currently a work in progress. Contact me if you are interested. I hope to have them packaged Real Soon Now and am working on using maps from Westchester County GIS.
NOTE: You will need 15M of free disk space for the DOS maps

Several additional local APRS digipeaters running aprsdigi have been added since then: W2AEE-1 covering the Northwest corner of the County; WB2ZII-14 near Peekskill and WB2ZII-15 near Yorktown Heights.
APRS automatic vehicle location and telemetry is used in many parts of the country for tracking resources during public service events and emergency responses. The WECA MIC-E gateway couples the excellent coverage of the WB2ZII 2 meter voice repeater system with the mapping capabilities of the several APRS programs now available for DOS, Mac, Windows, Linux, and Palm. In addition to personally-owned APRS trackers, WECA has packaged several Kenwood TM-D700 trackers that are used for a variety of public service events. These have callsigns like WB2ZII-1, WB2ZII-2 through WB2ZII-5 or so.
These maps have been made obsolete by Xastir and UIView's mapping capabilities.
