Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Answer: How To Get Latitude & Longitude of a Address using python
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…

Btreefs generates executable code at runtime to unpack btree nodes
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.

[Help] searching address
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.

Kako riješiti različite verzije istih adresa ulica?
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.

Let's build a Google Maps clone with React, Leaflet, and OneSDK
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:

MicroG Qs
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 )

Digital prepping must haves?
and nominatim which does the geocoding/reverse geocoding: https://nominatim.org/
- Bulk/batch geocoding for cheap?

How do I go about with this project idea
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.

pelias VS photon - a user suggested alternative
2 projects | 15 Nov 2023
Photon by Komoot is also using Elasticsearch for validating addresses and locations.

Autocomplete address from google places and mapbox seem to be extremely expensive. Is there any other good alternatives?
Alternatively, you could run your own Photon API: https://github.com/komoot/photon

The New GraphHopper Maps Route Planner
Open Source. The routing server is open source too and geocoding too.
- What is the easiest way to deploy OSM on the premise? like nominatim.openstreetmap.org, but offline version.
-
GraphHopper Routing Engine - Open Source Route Planning
To fully self-host a route planner (e.g. a "Google Maps" equivalent) you need GraphHopper for the routing and two other parts: you also need some visualization aka "maps" (e.g. with OpenMapTiles) and you need the address search (e.g. with Photon).

Question about privacy with Waze vs GMaps
There exists photon, but I don't know if it's used in any libre mapping app.

PSA: Use Acastus-Photon for better search for maps apps like OsmAnd
Acastus-Photon is an Android app that allows you to search up any address or point of interest on OpenStreetMaps and open it in OsmAnd or any other maps app. It relies on photon as it's open-source backend server (provides elasticsearch for OSM), so you can either use a public instance or self-host. This allows you to have search functionality as powerful as Google Maps whilst being able to use solely open-source software instead.
- OsmAnd~ address finding is terrible, copy and pasting lat and long is inconvenient, any alternatives that also respect your privacy?
What are some alternatives?
