There are several solutions to your request. Obviously, YAAC will be promoted here (since I wrote it for exactly this kind of work), although there are other Linux/Unix APRS programs. However, a 10" monitor is probably going to be too small for a bicycle event if you are at the Net Control station and need to be able to see the entire course in detail. I typically use a laptop computer connected to a 40" flat screen for those events, but I have AC power available at those events. Other events I know of that have indoor Net Control locations use projectors as monitors. Now, if you're using APRS in a support vehicle, then the 10" screen is probably enough.
Now using a USB-connected SDR (such as the RTL SDR dongle) instead of a conventional amateur radio rig requires a bit more. A program called rtl_fm can configure such a stick to demodulate FM radio (such as 2M ham transmitters), and couple its output into Direwolf as the software modem/TNC for AX.25 packets. YAAC then connects to Direwolf to provide the graphical views of the received APRS packets.
Here's a link with directions for setting things up with the SDR and Direwolf:
Hope this helps.

Previously posted on Facebook-APRS. It was suggested that I post here.
Looking for a APRS receive/decode/display map solution for a upcoming
race event. Most solutions revolve around an IGate. I would like to do
with a SDR, Raspberry Pi and 10" monitor. Suggestions Please. Note:
Internet unavailable. There are two digipeaters in the surroundings
hills that will cover the race course. Thx, Chuck N7CHS
