to measure distances and convert between our parameters I'm using TurfJS, for which binding is even more trivial:

Project mention: Am I thinking about geolocation/DB storage correctly? | /r/reactnative | 2023-06-19

Hey all, I'm currently using Expo's location plugin. This gives the user's latitude and longitude, which I'm storing in a Firebase Firestore document. I want to have a functionality where a user can select a distance radius (say, nearest kilometer, nearest 10 KM, and a global option which shows all) compared to the user's current location and show all available data within it. There's a library called geolib which can calculate the metered distance between two points. This is great, however I'm having trouble trying to think about how to query for these objects. I don't want to query ALL the documents and then filter down the documents based on their location on the FE, which means I'd probably need to query the backend for this specific data. This is where I'm running into some trouble. I'd basically have to have a firebase compound filter where I'm calculating the distance between the user's current location and +10 miles on the FE. Can somebody shed some light on this approach? I'm thinking: 1. Get users point 2. Calculate an arbitrary point that is essentially 10km away from users point (mathmatically?) 3. Query Firebase Firestore backend for results within that latitude/longitude. It just seems really complicated, and I'm wondering if I'm doing something wrong.

  Tools for editing Shapefile, GeoJSON, TopoJSON and CSV files

Project mention: Show HN: Geojson-shave, a tool for reducing the size of GeoJSON files | news.ycombinator.com | 2024-04-03

Have you thought about adding a simplification algorithm such as Ramer-Doublas-Peucker [0] or Visvalingam–Whyatt [1]? I've used https://mapshaper.org/ to do GeoJSON path simplification before and those seem to work very well. For applications which want to maintain path accuracy while reducing the number of waypoints that may be more effective than truncating the decimal places

Project mention: Overpass API x Python : how to fetch and analyze? | /r/openstreetmap | 2023-05-24

no suggestions on how to deal with the file size, but I image the issue with method #1 is that Overpass/OSM JSON is not GeoJSON. You'd want to find or create a python implementation of osmtogeojson https://github.com/tyrasd/osmtogeojson (this is what overpass-turbo uses to generate the GeoJSON you're downloading form it)
