Add new quest to determine the tracktype

[ENT8R]

This PR adds a new quest for determining the surface quality of a track. It fixes #487.

[westnordost]

Actually, I made an icon specifically for that, it's the tractor.

[westnordost]

A few points:

1. Whoa, how did you scale those, with MSPaint? Looking especially at tracktype 2,3 and 4 it really does not look so pleasant
2. On the pictures, the very much most important part of this quest:

• track1 shows too much sky and too little of the track. I cannot really identify the surface
• track2 looks kind of less smooth than 3, where should be the tangible difference between these?
• track4 is bad, it should have the same appearance (minus the track) than the other pictures, not this red-brownish heathlands

Uhh? I actually correlate this icon used here much more with "track/way surface" than a tractor. A tractor may be about agriculture, so a quest about plants on a field or whatever. (I know, not a quest we want.)

And if you considered to use the tractor for that, what did you want to do with this icon?

[ENT8R]

This was my tool/website which did this 😄 I fear this needs some adjustment...

I also thought that this icon would fit a little bit better...

Regarding the images: I will look for some better ones that will fit your proposals.

#279

[ENT8R]

Mmh... Alright. I find this still a little bit confusing.

[rugk]

Mhh ok. Considering the asked question, maybe the icon should try to represent quality somehow? Some +/- signs, 👍/👎 or so (in a simplified way) or so on a street, maybe?

[goldfndr]

Rather than quality, I suggest firmness.

[ENT8R]

track2 looks kind of less smooth than 3, where should be the tangible difference between these?

Maybe this is just because of the bad quality of the images, but I think grade2 is something like gravel and grade3 is sand or something softer...

[ENT8R]

track1 shows too much sky and too little of the track. I cannot really identify the surface

maybe this one is better?
Or is there too much forest?

Maybe it would be better if it had been photographed from an even lower position (i.e. frog perspective, but not looking up, but just straight on the road). Then you can also see more details of the surface itself.

BTW I also just noticed the question is a bit odd. "What is the quality?" -> "Soft".
An answer for the quality would be "Good" or "bad" or so. I would not expect "soft" as an answer. Maybe change the question to "What is the stability?", or, as it has been suggested "...firmness". Yeah, maybe firmness is the best.

[westnordost]

It would be ideal to have the different photos more or less show the same scene and in the same perspective but only have the track types differ. If on one photo, there is a forest but on the others, there are just meadows and shrubbery, people might be confused that this photo should be selected for tracks in a forest.
The perspective is fine, IMO. As said, it should be the similar to the other photos.

[ENT8R]

I changed the icon to the tractor now because the ways are mainly used by them. So it makes kinda sense to show it...
I also changed some images and rescaled all of them, so I would think that this PR is ready for another review...

[rugk]

because the ways are mainly used by them.

Only the bad ones, i.e. the ones with the bad quality. As this quest also can be answered with good quality/asks about the type in general, this argument makes no sense.

[ENT8R]

Well but for example the ways are allowed for (in German) "Land- und Forstwirtschaftliche Fahrzeuge" which implicites tractors... And I know also some tracks with a good surface quality like asphalt which can be used by tractors... I don't know which icon is the better one...

[westnordost]

Here would be some more pictures that might fit: #133 (comment)

[ENT8R]

I replaced the images of grade1, grade2 and grade4 with some of the images made by @BjornRasmussen in #133 (comment)
At least for me the difference between all of them is now pretty clear.
If you want to you can share your opinion!

[BjornRasmussen]

Nice use of the images!

[ENT8R]

Nice use of the images!

I'm not really sure if you released all images under the under the CC BY 4.0 license or only the images used for the path surface quest... Because I only found this comment where you stated that 6 images can be used but 2 of the images I used were mentioned earlier above and not in that comment. Would it be possible that you maybe release https://drive.google.com/file/d/1VzhiJin8IUIMFnQzOLeyDurttyeVPnbuXA/view and https://drive.google.com/file/d/1RJn5CW_AijVCWWtQ_cKHXmGFksTZ2ua9SQ/view under the same license too?

[BjornRasmussen]

Sure.
I release the following images into the pubic domain:
https://drive.google.com/file/d/1VzhiJin8IUIMFnQzOLeyDurttyeVPnbuXA/view
https://drive.google.com/file/d/1RJn5CW_AijVCWWtQ_cKHXmGFksTZ2ua9SQ/view

[westnordost]

The pics are really good now!

[rugk]

Maybe you can exclude tracks already tagged with "surface=asphalt" (if that is a thing/happens for "highway=track"), as there the track type value is quite obvious, it's level 1 and one would not need to ask a surveyor about that.

As for the images, yes, they show what we want, but what catches my eye first are actually the differences between the images regarding whether there are trees at the left/right. 😢
Maybe they can be edited away 😉
(And I still liked the original quest icon more than the 🚜)
