On a Debian 8 "Jessie" on a single CPU ARM "pi like" Pocket CHIP device
(https://getchip.com/pages/chip) takes 2 minutes 20 seconds to call up an old
Cloudmade map of my state Illinois. Has a 279mb footprint in the 3gb available
storage.I wish a solution along those lines could be pursued in the future. A
simple drop-in mapset along the lines of APRS droid with the 2.3gb offline
mapset that's available.If one doesn't have the skills to reduce map data, it
at least gives them a starting point. The Tiger and Cloudmade sets got me
started 9 years ago.
I had help from the group to reduce geo.pdfs and even though startup is cpu
intense, an old quad core laptop is pretty decent. I display the Cloudmade or
Tiger along withthe geo.tiffs and it's a pretty decent display. Kurt KC9LDH

Cool project.
This looks great for disaster/emergency situations. A bit of overkill for
standalone APRS operator, maybe.
I suspect the whole Pi question will come down to IO performance, which it
doesn't have. A NUC is already decently low power and it has very
respectable performance, CPU and IO. If you want to go lower power than
that, look at something like an Nvidia Jetson TK1 - 4+1 ARM cores, GPU,
SATA, mini-PCIe, gig ethernet.
