Dividers or Calipers for distance and time when planning a route.
Quote from BenHM3 on 25.11.2024, 20:29Hi Guido,
Navigators on a ship have a tool like a compass for drawing circles, but it has no pencil or pen. Just 2 points. One can set them a fixed distance, then put one point on the map, and swing the other around to find a fixed distance along the route. https://en.wikipedia.org/wiki/Calipers#/media/File:DividerCalipers.jpg
My idea for scenic is some kind of tool that would behave like ruler, for a fixed distance or time. Then one could swing it around from one point to find that distance or time away.
So I could have a ruler for 250miles (full tank of gas) or 2 hours (time for rest stops) then figure out where gas or rest stops might occur along a planned route.
Thanks Guido for Considering,
Ben

"Calipers" are the wrong analogy in digital interfaces. Maybe we select the tool and a cross or some other precision marker appears. Around it is a circle, the radius is equal to the time or distance we've selected. The circle's border equates to how far/fast the paths beneath it would allow you to get. The moment the cross touches a route we've already selected, BOOP, it reveals how far/fast you can get along that path.
If we've selected 2oo miles (the range of 1 tank), we can see the distance along that path we can expect to go. (If it's a high-speed route, maybe that's 200 miles. If it's a lo-speed route, maybe 225-250? If it's unpaved, 150-175? You don't have to invent that, we can set our best estimates.)
If we've selected 2 hours, the distance covered might be 140 miles on a high speed road, 90 miles in a city, and 50 on an unpaved road.
These are all just random thoughts I had on how the tool might be used by us. I'm aware that there are some real complexities on displaying a live-calculated radius, especially the distance-tool which can be so influenced by altitude changes. But maybe we can fake it, because even an approximation-tool would be helpful.

Thank you for your suggestion.
If I understand correctly, in the automotive navigation, what you are looking for, is referred to as Isochrone & Isodistance calculation. Here is a web-page with more information on that if you like: https://valhalla.github.io/valhalla/api/isochrone/api-reference/
The Scenic 4 map provider technically has this possibility.
A feature similar to this is already added to the feature request list. I'll add a link to this forum post to the list, so that I can reference it once I have time to look into this. This will take a while though, as I'm still working on getting Scenic 4 features back to Scenic 3 level.
If you have any further thoughts on this, please post another reply and I'll look into once I start working on this.
Thanks again and best regard,
Guido
