How to fix it please?
Is there any one to help pls? Thanks
i need to make route in indoor map leaflet from point A to B
how can i do this
we managed that by editing the routing file directly
more details please?
When the routing engine prepares a route, it generates a json file containing the routing instructions. You can see the details here. https://www.liedman.net/leaflet-routing-machine/api/#routingoptions. We used the map, drew a line representing the route to be taken including the route through the buildings. and then we added the waypoints manually.
we dont have maps in indoor its just an image
that contains details about places
you mean i draw line from point a and point b on that image and then aded waypoint manually
We used the map as the foundation, and used the leaflet tools to draw the line along the route that we wanted the user to follow. This route went through a harbour area, and major buildings, steps etc. To use the routing engine you will have to have it map based, but you can overlay any image as a base layer of course.
is there any example related to overlay anyimage ?
guys please help here

hi, I am a university student. for a project I created a small web app using leaflet and leaflet routing machine. I have a problem due to lack of experience in the sector.
I have this warning:
"You are using OSRM's demo server. Please note that it is NOT SUITABLE FOR PRODUCTION USE.
Refer to the demo server's usage policy: https://github.com/Project-OSRM/osrm-backend/wiki/Api-usage-policy

To change, set the serviceUrl option.

Please do not report issues with this server to neither Leaflet Routing Machine or OSRM - it's for
demo only, and will sometimes not be available, or work in unexpected ways.

Please set up your own OSRM server, or use a paid service provider for production."

to make the app usable, do i have to change the serviceUrl option?
how do it?

Hi there. I am new to leaflet, and just found the Routing Machine. Routing Machine does much of what I am looking to do, but I do not need routing via roads. I would like to route direct straight line waypoint to waypoint as would be done for aviation or nautical routes. Is this easily accomplished with the Routing Machine?

Is anyone here using GeoJSON Path Finder?
Specifically, I've got Leaflet Routing Machine working just fine with OSMR; plugging in a network geojson is good (I can display the network in Leaflet), but calling pathFinder.findPath() returns null.
I want more than one route between two waypoints but couldn't find any way.
do you have any suggestions?

Hello there ! its me again

so, i have my polyline now simplyfied and clean,

but there is some error in my itinerary,

To construct my itinerary i encode a polyline with a lot of coordinates, and for reduce them i take from the instruction only steps that have a modifier element
but sometimes it is not working like expected


on the capture, you can see the purple line, its my itinerary, and the red is the generated route
how can i do that ?

( its a simple example, but i have more complexe sometimes, its really weird, i dont know how is generate the route i have sometimes my route going into an impass and come back ??? )

prohibited direction is authorized but it doesn't seem to be taken into account.

I want to use Leaflet Routing Machine to draw a route - but to draw it slowly (so you can see the drive move across the country). Is there any built in magic that might make that easier for me?
Does anyone know analogs in PHP for translating route hints into a text description?

@perliedman hi, how to leaflet-routing-machine and GPS navigator real time ? can you help me.
Mauro Spivak
Hey there! I'm using LRM to create new routes as well as reading existing routes. Thereof, when I want to create a new route, I pass an empty array to the plan.waypoints option. However, if getWaypoints() right after initializing returns two "null" waypoints.
So to get around this, I decided that the first two stops added would be replacing the existing null ones. But this makes my waypointspliced event waaay too complex to handle and it made me think I'm doing something else wrong. @perliedman am I?
Kind regards, can you calculate the route by car, motorcycle or walking? Thank you
also, in apache cordova the biodecoding doesn't work, maybe you can check it? or show how it should be configured?
Is there a way to include the reversed route with the original route ? I mean, for example. to add a button beside that of "reverse route" to display both the original and the reversed route, and to sum them as a single route, as I am looping the route , one time from Start to End , the other from End to Start. I need to send the JSON or any form of data of the two ways to database in one shot. Note that not always the two ways are the same. Also, I need to modify each route independently. I mean, I can add some waypoints (vias) to the original route but not to the reversed route and vise versa. Can you help me with this ? Thank you
Good day! L.Routing.control draws those points that were not set, the line is drawn on other roads, is there any solution to this problem. Thank you in advance @perliedman

Hi !
I have a question for you because I cannot find the info in the doc, it's possible to configure a number of tiles to load? When I move around in my map, the leaflet-routing-machine trait disappears.
Thank you for your help !
I have some problems with my map and I don't know if it's possible. I have a route with multiple waypoints and you can drag new waypoints to the map. Is it possible to diferenciate this new waypoints from the others with the createMarker? @perliedman

Hi, it is possible to load the itinerary/plan without pass any waypoint as this example: https://cykelbanor.se/#bl=Karta

nvm I just found it is a different control and make it work, thanks.

Hello, I have created a kind of itinerary, but I would like to know if it is possible to remove the markers to just keep the path? Thanks a lot
