Hi

"Anyone willing to share their Camino Garmin maps (trail & tested) with us please?"
"Anyone also willing to share how to actually work these maps?"
I will spare you the one hour lecture, you'll be pleased to hear, and just give you a few bullet points for consideration but be aware that it is very difficult to condense several book-loads of information into a couple of paragraphs. It would appear, from your messages, that you're both just a little unfamiliar with the question of navigation and the systems used - correct?
- Modern navigation systems require three elements with an optional fourth being 1. time & position, 2. position within a particular framework / map (worldwide or local), 3. a location you wish to arrive at in the future or a route to follow and optionally 4. a record of your track & other alculations.
- There are several Global Navigation Satellite Systems (GNSS) for example the American GPS and European Galileo systems amongst others (it's worth reading some Wikipedia articles to appreciate the complexity of these systems). So if you have a GNSS receiver (Garmin, Trimble, Leica or a modern mobile phone) time and position of your location can be calculated - now you know where you are.
- A map is required to enable you to reference yourself relative to your surroundings, obviously the map must use the same reference framework as the GNSS system you're using. There are perhaps 100s of different maps and several different map formats, you just need to choose the map best suited to your particular application.
- A route from where you are now to where you wish to be in the future; a large, sometimes controversial subject as the "best" route depends on your vehicle, your tolerance for hills and route surfaces and other subjective preferences. Fortunately most Caminos are fairly well defined so there is really no "best" route.
- You may wish to record the path you travelled (your track) and perhaps know your speed, ETA, how far you are off the route, how long you've been travelling, time & distance to your destination, average speed, sunrise, sunset, altitude, ascent........ these can all be calculated from the original GNSS information (plus perhaps other sensors such as a compass, altimeter, pedometer).
- Some links for you to read around? GNSS MAPS but better if you do your own searches.
None of this actually answers your questions, apologies for the brevity, being somewhat off topic, I'm a retired (offshore) surveyor but have forgotten far more than I know now, later in the next chapter I'll try to answer your questions even though they are rather vague. Richard aka El Flaco
