What kind of data can be transmitted by APRS?

Automatic Packet Reporting System (APRS) is a versatile digital packet protocol used by amateur radio operators. It is most famous for transmitting live GPS position data to map the locations of vehicles, hikers, and high-altitude balloons. However, APRS is much more than just a tracking system. It is highly capable of transmitting local weather station telemetry directly to maps and databases. It also allows operators to send and receive short, tactical text messages to one another. Therefore, all the choices listed are correct.
