Nominatim VS Openstreetmap

You can simply use geopy API to get longitude and latitude from address. geopy includes geocoder classes for the OpenStreetMap Nominatim, Google Geocoding API (V3), and many other geocoding services. The full list is available on the Geocoders doc section. Geocoder classes are located in geopy.geocoders. Here…

I have had a lot of "fun" with this feature in the past. It has earned a permanent place in my setup script:

ALTER SYSTEM SET jit=off;

Basically a performance blackhole for more complex queries. Most OSM related projects disable it straight away as it only creates headaches.

https://github.com/osm-search/Nominatim/pull/2559

Because osm.org and OsmAnd use different search engines. On osm.org it uses the Nominatim geocoder which is good at parsing addresses the way we are used to writing them. It is also running on a server with a lot of storage and memory resources. OsmAnd is built for offline use so it can't use Nominatim and has much more limited computing resources available to it. It is searching through the map files locally on your phone and however they have chosen to implement that search algorithm seems to perform poorly on addresses.

Ako skupa s adresama imaš i njihove lokacije možeš i koristiti gotov geocoder (e.g. Nominatim je free i koristi OSM podatke, možeš i deployati svoju instancu), pa iz rezultata naći geometrijski najbližu adresu koju imaš.

Then implement a use case. We are going to use Geocoding use case with Nominatim provider. But you can, of course, use a different provider. Copy the example code into your server.js file and make a few changes, so we can send the information we will receive from the user:

There are reasons why this tech was developed: because GPS can take a long time to sync up to the satellites, because GPS often doesn't work indoors, because your phone can keep a local cache of locations, and so you have the ability to find places by name or address (Geocoding) using nominatim ( https://nominatim.org )

and nominatim which does the geocoding/reverse geocoding: https://nominatim.org/

Then it depends on how the location data is conveyed in the group chat. If it's a text message you need to parse it and possibly use a mapping service to do geocoding. Eg. convert "22 Main Street" or "upper Brooklyn" into GPS coordinates. Besides Google Maps API you can maybe use OpenStreetMaps via Nominatim. If it's something more like "we just passed John's house" then you need to figure out how to write some logic to determine a location from that. Or maybe they just used the WhatsApp location share feature, then you probably don't need mapping at all.

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

> 9450 S. W. Barns Rd

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
