I'm aware of of the Netrom, BPQ, ROSE packet type nodes. I'm just trying
to get my head around what I see on the map as a Node.

True.

The answer to my question on askgeeves
What is a Node?

(1) In networks, a processing location. A node can be a computer or some
other device, such as a printer. Every node has a unique network
address, sometimes called a Data Link Control (DLC) address or Media
Access Control (MAC) address.

(2) In tree structures, a point where two or more lines meet. 

Which, if (1) is taken literally, every APRS station is a node. :-/
But would (2) any make more sense?

I've come to the conclusion that a Node in APRS could be any of the
packet nodes above, multiple (or single) frequency, or a cross port APRS
UIdigi, or an "access point" to a network, like IRLP or similar.
