to specify a route; it calculated all major roads around you into a point cloud and then fit a convex hull around it, so you could instantly see your range in all directions. Performance is critical on that, however. We had big performance issues on ours (had to do cloud computing), although I've since come up with lots of ways I could have made the program orders of magnitude
climatology data to estimate the likely weather at that point in time. We also had a driver profile that affected how aggressively the driver drove, although you had to manually configure the profile, it didn't gather it from real-world driving data.
One of my favorite things (which we were still refining at the time the company went under) was a mode where you didn't have
dropping down into a canyon with hotter weather. Head, tail and crosswinds were also taken into account, including an adjustment to account for wind fluctuation (crosswinds were modeled by a vehicle-specific reduction in drag coefficient). Recent rain / snow affected your rolling drag. We also had a mode where people could plan trips in the future, and it would use
I'm particularly interested in whether you take weather forecasts into account. In our calculator we automatically collected GFS forecast data - and then to interpolate between weather stations, the program also included an altitude adjustment, since you might have two low altitude stations but you could be passing over a mountain pass and have colder / windier weather, or
upper left, sometimes tiny Xs in the upper right, and sometimes (for example, the question mark icon) no close icon at all.
I'm still really curious as to what's going on under the hood. Many ages ago (back when Roadsters were just starting to hit the streets) I wrote a range calculator for a company I was running (which later went bankrupt :Þ), so I have a bit of a background in this.
Wow, that was amazingly responsive of you! Elevation data now looks good - thanks for that. And actually I was wrong about speed limits, they seem to be getting it right. Nice that your program remembered my settings too (I had closed the tab); you've done some really nice work. The only weirdness to me is the close icons, they're inconsistent - sometimes giant Xs in the
Hi - I'm just trying out A Better Routeplanner - neat tool there. But can you verify, does it actually have altitude data for Iceland? I don't see any way to see a breakdown of what the tool thinks is happening along the way. Also, I'm kind of interested in the nitty gritty of what it takes into account (for example, weather forecasts?) and how the vehicle profiles are built.
