Open Source Routing Machine (OSRM) VS Openstreetmap

then called the Open Streetmap api described here using Power query: https://github.com/Project-OSRM/osrm-backend/blob/master/docs/http.md

OSRM: A super fast and easy to use routing engine that runs on OSM data. You only need to run 5 lines of code to (1) download a .pbf from Geofabrik, (2-5) download the OSRM docker image and pre-process the OSM data. There are also 3 profiles predefined that you can use: car, bike, foot (e.g. foot.lua). It basically hosts a local server. I find the easiest way is to combine it with the osrm R package. I have seen you also need to adjust for the elevation. I think I have seen some custom LUA profiles that also account for DTM derived elevation changes as an additional weight.

I am trying (and failing) to setup an OSRM instance with docker compose. The issue I've encountered is with setting up osrm-backend. According to the Github and Docker Hub pages, the process is as follows:

I am creating Rust bindings to https://github.com/Project-OSRM/osrm-backend using autocxx. This allows for fast routing on openstreetmap data. They have a nodejs server, but I'm going to write a Rust one with these new bindings. I am finding that many of the config classes in C++ are't Plain-Old-Data structures, so are opaque structs, so I have to write getters and setters in C++.

Have you tried the OSRM bike config? (The one you find in https://github.com/Project-OSRM/osrm-backend/blob/master/pro...)

This is a 30 second exercise on OSRM, or any other service that provides directions.

As for the rules for routing algorithms, OSMR's foot profile looks like good place to start. You could copy the file into something like for_women.lua and extend it with rules for e.g. street lighting and any other features of interest. Of course, it would be best to reach out to the other devs first.

I'm trying to calculate walking distances using OSM and OSRM but this results in distance matrices that violate triangle inequality. This is a pretty bad issue for the spatial models I'm building. I was wondering whether there are alternatives to OSRM that guarantee that triangle inequality is respected. Mostly, I really don't care about the routing algorithm looking at red lights, whether streets are one or two way streets, private roads, etc. I just need the distance along pathways between points.

I wouldn't compare osm-website and osm-carto at all. The commit logs are very different.

openstreetmap-website: https://github.com/openstreetmap/openstreetmap-website/commi... . Numerous commits most days.

openstreetmap-carto: https://github.com/gravitystorm/openstreetmap-carto/commits . So far in 2024; one small regression fixed, one niche bit of tagging added to an existing style, some largely pointless code style tidying. That's it.

Contributing is simple:

1. When you see a trail or any other feature that doesn't appear on the map, take a picture.

2. When you get home, visit https://www.openstreetmap.org and start drawing.

The website has satellite images overlayed wirh map data, so it's easy to see what you are doing.

You can look at your pictures to remind yourself of what was missing.

If you have recorded your ride,you can also upload your GPX trace to OpenStreetMap to make it easier to trace features that don't show up clearly on satellite images.

What impressed me was that it looks like openstreetmap shows the bridge as down already.

Through the Fast Forward program, we give free services and support to open source projects and the nonprofits that support them. We support many of the world’s top programming languages (like Python, Rust, Ruby, and the wonderful Scratch), foundational technologies (cURL, the Linux kernel, Kubernetes, OpenStreetMap), and projects that make the internet better and more fun for everyone (Inkscape, Mastodon, Electronic Frontier Foundation, Terms of Service; Didn’t Read).

Way overdue. OpenStreetMap's website at openstreetmap.org is its calling card, and for the past few years the default style shown (called Carto) has all but stagnated in development. Accepted features like highway=busway (introduced three years ago) are not rendered there because the maintainers can no longer be bothered, or dislike the tag personally despite broad community backing.

What worries me for this new effort is that Paul Norman is one of the two remaining Carto sometimes-active maintainers who refuse to merge contributed PRs or even provide alternative minimal support for features like highway=busway, leading to awkward gaps on the baseline map shown on openstreetmap.org.

I would love to be surprised in a positive way about this new effort, but I'm not holding my hopes up. Thankfully OpenStreetMap can be thoroughly useful in apps like OsmAnd and OrganicMaps, and the tile-based Tracestrack Topo layer on openstreetmap.org is getting quite decent:

https://www.hotosm.org/tools-and-data runs software that's used for example after an earthquake. The tasking manager specifically is a reactjs app plus postgresql with plenty of open issues. HOTOSM has full-time staff, I'm not sure if the developers are full-time, but it's more organized than a volunteer project.

https://github.com/openstreetmap/openstreetmap-website/ is Ruby on Rails (easy installable with a docker setup). The maintainers have trouble even reviewing incoming PRs so an experienced person who can triage, test, review is currently needed.

If you're in the US then https://en.wikipedia.org/wiki/Code_for_America might be worth having a look at.

https://summerofcode.withgoogle.com/ will soon annouce vetted organizations who do open source. (last year https://summerofcode.withgoogle.com/programs/2023/organizati...). Project are paid, the process is long though, all summer. https://developers.google.com/open-source/gsoc/timeline

Portlandians: Are Barns Rd and Barnes Rd the same thing? Looks like a nice spot if so: https://www.openstreetmap.org/#map=18/45.50901/-122.77468

That building is now a SFX agency: https://hellohinge.com/ (No relation to the dating app)

Also curious if the TEKsystems employment agency next door took its name from Tektronix.

Yes, https://www.openstreetmap.org has quite inconsistent detail as it relies on people mapping stuff.

And help is welcome, anyone can join and help with mapping!

It's shown on OpenStreetMap, but not as a street: https://www.openstreetmap.org/#map=16/51.3682/1.0330
