Openstreetmap-carto: Render conveyor belts (man_made=goods_conveyor)

[kopiersperre]

man_made=goods_conveyor is used nearly 1000 times. Conveyor belts are relevant for bulk materials (coal, iron ore, copper ore, lime, wheat, corn) at open-pit mines, port terminals and industrial plants.

As alternative sometimes railway=monorail is used (example: http://www.openstreetmap.org/relation/62366#map=14/51.3573/10.5061) which then could be abandoned.

We don't have much industrial or port infrastructure rendered. Do we want to? If we do, is this the best place to start?

[imagico]

Considering how many variants of this kind of feature exist having a clear wiki page would be important.

I am also not sure if it makes sense to render this and not man_made=pipeline - see #640

I have also seen them mis-tagged as aerialway=x

I'm sure we should render both, particularly the large conveying structures on open pit mining sites (if they are mapped with this tag)

[kopiersperre]

@mboeringa May you give me an exmple for aerialway=x?

[mboeringa]

@mboeringa May you give me an example for aerialway=x?

@kopiersperre, here is what I think is a classical example of this kind of mis-tagging:

https://www.openstreetmap.org/#map=17/50.09801/8.65217

Clearly this feature in the middle of an industrial power station must be (also looking at the aerial in ID) a conveyor belt, no aerialway makes this kind of abrupt direction changes.

Of course, with the man_made=goods_conveyor not being included on the main man_made=x Wiki page (http://wiki.openstreetmap.org/wiki/Key:man_made), but only on a less accessible proposal page (http://wiki.openstreetmap.org/wiki/Proposed_features/Goods_conveyor), the chances of mis-tagging are bigger.

[pnorman]

I like the idea of rendering more industrial features, an feature space where we don't do much and there's normally room on the map. But the tagging needs more consistency, better documentation, and wider usage. It may also be best to start with other industrial features like man_made=pipeline.

[turnsole80]

Is there any thoughts on re-looking at this issue? Rendering industrial objects could be quite handy

[kocio-pl]

I'm not aware of any. It's probably most probable if you take care of it.

[turnsole80]

I can do that :)

I want to clean up some of the tagging first. But this is a good an issue as any for me to cut my teeth on

[kocio-pl]

Cool, so I reopen the issue. I'm not sure that such design is the easiest - we have special tags for what we think is good for novice osm-carto developers, but it's always better to do what really interests you.

man_made=goods_conveyor is now used 3500 times and has a wiki page. Usage chart:

However, as mentioned above, we should probably render man_made=pipeline first (or at the same time).

[pnorman]

I think the answer to this being the place to start is no. It makes no sense to render this in isolation.

[EwenH]

Take a look at this long conveyor belt in Western Australia. This belt extends the bicycle route by over 10km however you wouldn't know about why the diversion is in place if you are looking at OSM. Having the conveyor belt rendered explains why the railway exists, why the industrial is next to the railway line and how the ore is shipped. We are not telling the full story otherwise.

[jeisenbe]

Used >4200 times, added to Key:man_made and Map Features as "de facto" after discussion on the Tagging list.

There is an open PR (#4070) to render man_made=pipeline features, which was considered a prerequisite.

If that PR is approved, we might consider rendering goods_conveyor, if someone can develop an intuitive rendering which can be understood next to aerialways, railways, pipelines etc -

Are there any examples of digital or print maps which show this feature?

[jragusa]

Why not a similar pattern than aerialway=goods with closer rectangles

[jeisenbe]

That might work, but it would need to be clearly different than other aerialways.

[jragusa]

Starting point:
https://www.openstreetmap.org/way/627540810 at z18
dash/line-dasharray: 6,6;

dash/line-dasharray: 24,6;

dash/line-dasharray: 24,25;

aerialway=goods pattern for comparison
https://www.openstreetmap.org/way/191254475

[jeisenbe]

line-dasharray: 6,6 is the best of those 3, but the color is a bit strong. Is it #707070?

Aerialways are dark gray because they are transportation features which are open to the public, but this is an industrial feature.

Try #808080 or #999999 perhaps?

[jragusa]

Yes it's the #707070 but actually the correct value displayed above is line-dasharray: 12,6, my apologies.

line-dasharray: 6,6

line-dasharray: 12,6 + #808080

line-dasharray: 12,6 + #999999

[jeisenbe]

#999999 seems to be an improvement. It will need testing next to other features with a similar color, like service railways for example.

line-dasharray: 12,6 appears to work, but feel free to try some other variants.

[jragusa]

line-dasharray: 12,6 + #999999 along service railways

https://www.openstreetmap.org/way/163719139
https://www.openstreetmap.org/way/163719140

feel free to try some other variants

The four patterns showed above are the main alternatives to get a distinct pattern than those of aerialway=goods. Then we can adjust finely line-dasharray if neccessary.

[jeisenbe]

I would recommend opening a "draft" PR and working more on it there
