I have been working on a project that has multiple repos, all of which have to convert between multiple map coordinate types, so I made an NPM module that allows you to parse and convert between Decimal Degrees, Degrees-Minutes, and Degrees-Minutes-Seconds coordinate types. Niche? Yes. Useful? Also yes (I hope)!

I've recently been working with real-time geoJSON data at a rate of 50+ queries per second. SaaS solutions can be prohibitively expensive at this rate, thus, I created go-reverse-geo. Data is pulled from geonames.org and is stored in MongoDB (a requirement of my current project). It is very much a work-in-progress (I wrote it this morning). Hope someone finds it useful. https://paranoia.dev/vivi/go-reverse-geo

Hi HN, I made a web game to practice country locations a while ago and HN liked it, so I thought I'd post my updated version as well. As for how the game works and feels, I'd really recommend you checking it out for yourself, it's free, no signup, no ads. The tech stack is Vue + ts + Tailwind/Daisy for the looks. The learning algorithm is a slight modification of the ts version of FSRS. If you have anything to add, it's open source as well (https://github.com/koljapluemer/learn-worldmap), although not well documented yet. In the end it's just a little sideproject,…

I figured this might be useful to folks. It's a simple PHP server that requires a single-table database (It's fairly "agnostic," but all my uses are in MySQL). I won't publish any of the servers that I've set up for my apps, because someone is bound to write an application that drives my bandwidth into the stratosphere. I could definitely take it further, but this gives me all I need for my purposes. Here's an app I wrote, that uses it: https://apps.apple.com/us/app/we-are-never-alone/id650482602...

Hi HN, I built a little tool to help me get better at remembering country locations on the map: https://learn-worldmap.netlify.app/ It's made from plain HTML/CSS/JS, and not intended to make any money or anything. Just thought that maybe someone else may enjoy it. Also of course happy about any feedback! Cheerz.

I wrote a tool in Python that finds the school district associated with any given street address in the United States. Here’s how it works: An address corresponds to a single point on the map. The U.S Census Bureau has a geocoder that converts an address to latitude and longitude coordinates. School district boundaries can be represented as polygons on the map. The National Center for Education Statistics (NECS) has geographic data on school district boundaries. Once we determine which polygon the point resides in, we know the school district.
