Hi
In the scenario I was referring to (digital map displayed on GPS used to navigate at night) even the most skilled night time, compass bearing, paper navigator would come a distant second. Scenario - 20m wide spaced traverses back and forward across a ~30 ha square area making sure you didn't cross the same path twice if possible..(and marking waypoints as you go for various reasons for an accurate record of observations (~ 5m accuracy achieved) - try that with a "paper map and compass" and be as accurate). I wasn't referring to hiking across some wide area from point A to point B - very much easier.
In my example I am using air photos not maps ..so I can see trees, fencelines ect - much better than even a 25K scale paper "map" in many cases...though I generally have a paper copy so maybe that is irrelevant :)
As I said - WHY...meaning why would you use a less effective method (what you are suggesting) for all scenarios. Wasn't saying it wasn't possible to navigate "at night" with a compass and map - obviously this has been done before many many times.
Also many digital maps are just scans of paper maps - nothing hidden - its just not paper. You are referring to GIS mapping - still digital mapping but a bit more complicated for the uninitiated.
Again - use what combination of navigation aids best suit your requirements and this includes taking into account your level of knowledge on how to use them. The old paper map (even without a compass - e.g. just cruising the tourist
routes) is possibly the easiest way for many punters. Crossing over to using digital maps/gps often requires a bit of a learning curve. I think this is more the problem than just the "digital map" itself...and why we get these threads every 6 months or so.
Cheers
