brouter-web leaping around, legend is huge #59

Is there an easy video guide to using this router? It's behaving weirdly (on a Mac, in Chrome, with latest MacOS and Chrome version). It won't cancel routes, when i try to size up or down the map it leaps wildly from a street to a country, the 'legend' section on the left has decided to take up half the screen. It's not at all user-friendly.

Can it be related to available web technologies on Mac ? Similar and worse issues are experienced in Android browsers, as BRouter-web functional compatibility with Android browsers is in progress yet.

Good point, poutnik; I also have trouble with my country's Ordnance Survey maps, which can be scrolled back to see how the maps looked in 1650 or 1847 or whenever you like.

But a little more GUI help would be nice. This would be a lovely routing aid for things like my planned cycle across the Esker Riada (the neolithic roads across Ireland on gravel ridges) from Dublin to Galway, if I could get it to work. It would be handy dandy to be able to make a circle of say 10km around my home and then plan a series of cycles radiating out from the centre and save and refine them, if it were a little more user-friendly.

And is there any way to make the legend a little more discreet? Damn thing is taking up half my screen! Preferences that could be changed would be nice (well, maybe they're there already & I'm just too stupid to find them.)

And what is this? I know my childhood was a bit all-over-the-place, but gee…!

Not to mention this - target island? say what? (The context is that I was experimenting with a cycle route along the cycle-walking path by the river; for some reason Brouter is gulping and spitting at this.)

It's also doing something that maddens me in Google Maps - I drag the line, it decides for me that no, the nice riverside cycle lane isn't suitable and I should cycle on the road with the trucks. I drag it again to try to re-educate it. It has now added half a kilometre on to the route. So a route that Strava says is 16.6km is now 18.7km according to Brouter.

To the target island - the destination point is either too far from the OSM routable way network, or at the wa network, but not reachable according to used BRouter profile routing policy.

Routing is not based on neural network learning. It is based on OSM ways data and the BRouter routing profile you use ( standard or custom ). If you are not satified with the route generated for you, you have 3 choices>

  • Use different routing profile
  • Drag a route toward a way you want to go through, it will ad a viapoint there.
  • Modify paramaters of the profiles.

For that, maybe brouter-web could be a bit more userfriendly and displays some generic-error instead. Because basically this errors means "cannot find a way to go from the start to the end", regardless island.

way is any line-like structure in OpenStreetMaps
network is any connections of line-like structures via points called noded.
routable is such a OSM way with tag haigway=*, with meaning generalized road ( from motorways to pedestrian paths ), that is by law and by the profile policy allowed for the vehicle/pedestrian to go through.

So routable way network is connection of all OSM highways that are in current routing mode allowed to use.

neural network learning - forget it - it is not used in context of BRouter engine backend nor BRouter-web fronend GUI.
( If interested, it is way of human or machine learning by providing example cases in learning phase and then deciding the cases based on what was learned. )

In fact not, The target island error is more specific. The other option is a forbidden bottleneck on the road.

Yes indeed, I cannot actually reproduce it locally. Could you share (or @Tamhlacht) any url reproducing this issue?

poutnikl commented Dec 22, 2016

@bagage Not handy. which of them ?
The island one you can achieve in rural areas to place destination far enough from any road/track/path.
The denied bottleneck - the exact error wording I do not remember - try to make BRouter to route you via forbidden way ( e.g. motorway on bike, or a car through path ). eventually cut off via nogo areas all other ways that are usable.

Like schema
placed nogo circle - allowed way - start - allowed way - not allowed way - allowed way - destination - allowed way - placed nogo circle

Is there any way to make the big legend take up less space? It’s not fulfilling any very useful function most of the time, but it’s covering nearly half of the screen.

#56 is dealing about that yes, but it's not finished yet because none of us are web developers expert unfortunately. For now there is no way to reduce the legend width. But it should not take that much space, only 400px width:

2 hints - in the bottom right coner one can copy permalink to provide the link to the scenario.
Data link above the left botom text field provided OSM tages for suggested route segments.

The Black Point icon with a hing Draw no-go area ( circle ).
The icon with magnifying glass means textual search ( 3rd part online resource ) , either name, either coordinates. the latter is picky, not all coord. formats are accepted.
Permalink serves rather for hoovering over and copying the link to clipboard. then paste to link where you want. Following the link provides BRouter-web with chosen map, region, zoom, start, destination, used(standard) profile + optionally viapoints.

It uses OSM or other online world-wide place database, so it finds what result is provided.

this link is the state of the BRouter-web screen. You can share the state of the screens by sharing the link. After the copy, use it as any other URL link, in the browser address field, or share it as any link anywhere you are used to share links.

for the route itself, you need to download the GPX files, containing the route.

Brouter IS a downloadable Android program, usable standalone, or as the 3rd party offline routing engine
in Androind GPS applications OSMAnd, LocusMap or OruxMaps.

For the help and discussion, the better place then the issues is the Google group "osm-android-bikerouting", common for BRouter application and BRouter-web.

Even though. Github Issues are to be considered as feature request and bug tracker. Issue discussion are rather for issue or new idea/feature clarifications, suggestings of workarounds or issue fixes.

GPX provided by BRouter-web is not Android specific and can be used in any GPX aware application in multiple platforms.

what is essential is the very specific features and abilities of BRouter for the bicycle routing, unseen anywhere else. See e.g. https://github.com/poutnikl/Brouter-profiles/wiki

I access the Brouter Google group personally via maillist interface only.

If I got it well you ask about the map zooming in/out. I have noticed in past that on some machines/browser/mouse(?)/mouse driver(?) combinations, zooming by the mouse scrolling is too sensitive. In such a case is preferred zooming via zoom in/zoom out icons. I am not aware of a way to address it, as it is local environment dependent.

I have supposed you got the mouse behaviour experience may differ between various webpages, so you should not be surprised Google Maps and Brouter-web may behave differently. I remember once it behaved like zooming fine on one my computer and zooming like zrazy on the other. But as I am not the author, I cannot change anything on it. I can only advice to use zooming icons instead.

You need to register at GG as the member of the group and the configure it to use the email gateway to receive and send the posts. You may want to create a dedicated Gmail account for this or similar cases, not to expose your eventual personal email.

Hm, that is very strange, related probably to similar mobile browser issues. But just guessing.
( I suppose you do not confuse them with eventual browser feature to zoom a general page.)

Edit: Until today I have thought desktop browsers work fine.
