Proportional Pathing

Issue #80 resolved
David Armbruster created an issue

This suggestion is probably somewhat related to the option to use a manually set path. Having a way to do a decaying path (e.g. path hop and rate tuning) would be tremendously useful for me.

Existing APRS options rarely offer a way to explicitly do proportional pathing. Bob, WB4APR, has written about it here:

Although to be honest it would be more useful in a mobile setting than fixed. Perhaps this suggestion is more appropriate for an iOS app rather than for laptop/desktop such as QTH. Yet having a status once an hour with wider digipeat with the bulk being local would still be useful.

    I’ve been thinking about how to implement proportional pathing. My difficulty is that I was intending to implement a beaconing algorithm for mobile operation similar to SmartBeaconing or GeniusBeaconing. Both of these algorithms vary the rate of beaconing in response to changes in speed, acceleration, turning, etc. The proportional pathing spec seems to be defined in terms of fixed rate beacons, i.e. every minute.

    So, for example, if you had SmartBeaconing’s slow rate set to 10 minutes and you were stationary, what would you expect the path to be? Then, when you started moving again, and the rate sped up to, say, every 2 minutes, what would the path look like then? Generally, the faster beacon rate means that the packets contain important positional updates. Would the proportional pathing operate independently of the beaconing algorithm?

    The article on "The Human Touch in Data Annotation" is a must-read for anyone interested in the field of automation. The author does an excellent job of explaining why human involvement is still necessary in the age of automation, especially when it comes to data annotation. The use of words like "precision," "accuracy," and "nuance" perfectly captures the experience of using human touch in data annotation. Overall, this article is informative and well-written, and I highly recommend it to anyone interested in the topic
