Visualizing unpaved roads

[Steve Jarrell]

Re: Unpaved roads vs color contrast and permanently closed roads motorcyclists

In my area I ride a combination of paved and unpaved roads when I'm on my smaller motorcycle (Husqvarna Svartpilen 401), however I like to avoid the unpaved sections if possible when I'm on my larger touring bike (Honda Goldwing). It's really nice to be able to quickly visualize that route and see if it has unpaved sections, and if so how many there are and how long they are.

The Kurvinger.de route planner solved this issue using OpenStreetMaps both on the map itself and in their elevation view. In the following screenshot the blue sections are paved and the brown are unpaved.

It would be GREAT if MRA could implement this feature in the future!

Steve open the route in the here-map and see the unsaved roads are grey

@hans-van-de-ven-mra-master Unfortunately that's not the case with many unpaved roads and the Here maps (at least in my area). Even if they were shown in a slightly different color, once I've made my route the route line covers up the different color that indicates that it is a dirt road, so if I go back to the route in the future I have no idea it goes over an unpaved road just by looking at it.

Take a look at the screenshots below that illustrate what I'm talking about. Technologically it is possible to show unpaved roads very clearly as routes are being created and afterwards using OpenStreetMaps. Whether that's a feature that's worth investing development time in or not is another question entirely.

Thanks for your help! I sincerely appreciate it!

@steve-jarrell

Mm, ok, that is something that is not in the OSM map that MRA use.
I will ask the developers

[Steve Jarrell]

@hans-van-de-ven-mra-master Thank you very much. I'm sure it's a feature that any on and off road adventure rider would find to be extremely useful.

Best regards,

@steve-jarrell I agree, more shopuld be done for off-road riders or dirty-raod riders !

@steve-jarrell @steve-jarrell Steve,
I think that will be a tough one for every developer : I have been looking at the stretch you mention, and in none of the map materials which are available in MRA Gold (and there are a lot of them), I nowhere notice any difference between paved and unpaved. I specifically mention the stretch of road one the crossing of Sky Valley Road and Old CCC road. South of that crossing and North of it should be differently colored if I understand you correctly. In none of the maps there is any difference between both.

So I think not any developer will be able to show you any difference at that particular spot : it all depends on the map material the developer has available. You may edit the OpenStreetMap material there, however...

[Steve Jarrell]

@sudolea I'm not sure I understand. Just because we're not seeing the data on MRA's maps doesn't mean that it's not available from the source.

Kurviger uses OpenSource Maps as does MRA. It's obvious that the data is available in OSM and that it can be presented graphically. I export a .gpx file from MRA to Kurviger and I can see the off road portions of my trip perfectly.

I found the same issue with POIs that I posted about a couple of days ago. Kurviger and MRA both use OSM for POIs, and yet Kurviger shows MANY more pertinent POIs than MRA does.

Since OSM is open source, if there's a reason that data is available to Kurviger that's not available to MRA I don't know what it could possibly be.

As I said previously it seems like the data that's needed is there to implement this feature, however whether or not it's worth the development time to make use of it or not is another issue.

Best regards,

Steve

@sudolea I haven't looked at the source data provided by OSM, but my guess is the "surface" tag as defined here is what is being used by Kurviger to determine which roads are unpaved.

Best regards,

Steve

[sudolea]

@steve-jarrell Interesting. I went and looked it up in OSM (had to log in and start editing before I saw it). Indeed, the "surface" property is different (gravel vs. asphalt). So it would (in principle) be available indeed. I missed that one

[Steve Jarrell]

@steve-jarrell I just looked quickly at this same area directly in OSM. If I use the "Standard" layer I can't see that this section of the road is unpaved. However, if I use the "CyclOSM" layer I can it clearly.

My guess is that Kurviger is using the unpaved road data from the CyclOSM layer to depict unpaved roads on their standard maps. I don't know whether that's possible for MRA's developers to do or not, but I think it's worth consideration.

Best regards,

Steve

@sudolea Thanks for the update. I have just started using the OSM editor to add some local information so I may need to reach out for some help!

Thanks!

Steve

[sudolea]

@steve-jarrell Steve, I myself have also already edited some OSM map data; most of the times I don't feel very confident about my edits. However, there is an option to ask people who are more familiar with editing the map material to audit your changes before they get "live"...

[Steve Jarrell]

@sudolea Thanks. Yes, I saw and checked that option. It's not real intuitive. It will tell you there's a potential problem, but it doesn't give you hardly any indication of what the problem is or how to resolve it. I guess I'll have to watch a few more of the videos and read more of the manual. I'll figure out the basics.... somehow..... someday.

Thanks!

Steve
