Open Source GIS – An Interactive Infographic

In plain words

Open Source GIS is an interactive infographic tool designed for developers and GIS professionals. Launched in 2020, it provides a visual guide to open-source geographic information systems technologies and their relationships. The tool helps users explore and understand the open-source GIS ecosystem, making it easier to navigate the various available options and how they connect to one another.

  OpenFreeMap – Open-Source Map Hosting2024 · openfreemap.org · ▲848

  Hi HN, After 9 years of running my own OpenStreetMap tile server infra for MapHub (https://news.ycombinator.com/item?id=11389989), I've open-sourced it and launched OpenFreeMap. You can either self-host or use our public instance. Everything is open-source, including the full production setup — there’s no 'open-core' model here. Check out the repo (https://github.com/hyperknot/openfreemap). The map data comes from OpenStreetMap. I also provide weekly full planet downloads both in Btrfs and MBTiles formats. I aim to cover the running costs of the public…

  Every mountain, building and tree shadow mapped for any date and time2024 · shademap.app · ▲685

  I've been working on this project for about 4 years. It began as terrain only because world wide elevation data was publicly available. I then added buildings from OpenStreetMap (crowd sourced) and more recently from Overture Maps data. Some computer vision/machine learning advancements [1] in the past few years have made it possible to estimate tree canopy heights using satellite imagery alone making it possible to finally add trees to the map. The data isn't perfect, but it's within +/- 3 meters of so. Good enough to give a general idea for any location on Earth. Happy to answer…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Linux sysadmin course, eight years on▲780

  Almost eight years ago I launched an online “Linux sysadmin course for newbies” here at HN. It was a side-project that went well, but never generated enough money to allow me to fully commit to leaving the Day Job. After surviving the Big C, and getting made redundant I thought I might improve and relaunch it commercially – but my doctors are a pessimistic bunch, so it looked like I didn’t have the time. Instead, I rejigged/relaunched it via a Reddit forum this February as free and open - and have now gathered a team of helpers to ensure that it keeps going each month even after I can’t…
