Products that do what Global Ground Station Database – 650 Satellite Ground Stations Mapped does
Hi HN, I've been working on a project to address a challenge I faced in the space industry: finding reliable and comprehensive information about satellite ground stations. It often involved piecing together data from scattered sources, which was time-consuming and inefficient. So, I built the Global Ground Station Database (www.find-gs.com). It's a free, searchable directory of over 650 ground stations worldwide, with locations mapped and key details included. The database is built with [Python + React]. We're focused on data accuracy and completeness, and we're constantly adding new…

A web platform I've written to make it easy for people to share goespatial time series data and display it on animated heatmaps. There's also a social media component that allows you to write comments, follow, share and like data sets that you want to engage with. You can also download the CSV data and embed animations into your own websites. People uploading datasets can also choose to make money by accepting donations. Please check out the home page for more details: https://mapipedia.com Here are some samples of things created with the platform (press the play button to start…

Hello HN! My name is Rémy and I recently published an astronomy dashboard where everything is open source: the code of the website, the framework it is based on and the library that computes astronomical data. For the last few years, I have been developing the Ruby library Astronoby (https://github.com/rhannequin/astronoby) with as much dedication and perseverance I could while I don't have any scientific academic background. My end goal was to use this library and build a website that not only provides as much data as possible, but let anyone access and understand how it…

I have created a single map that lets you easily browse all bus, tram, metro, ferry and train routes. I’ve loaded some data from Europe, Israel and India. It's called BuzMap: Here is an update, there is a previous outline linked at the bottom State of the BuzMap - http://buz-map.com I have done significant work over the last 3 months to get BuzMap further towards a usable product and at least prove the scalability of the architecture and I hope a glimpse of where we can go with this.. I have what I think is a viable user interaction model. Upon touching or hovering over a section…

Hey there, I'm an OpenStreetMap enthusiast and I was curious what kind of impact the app I am using has (I use StreetComplete[1], an easy-to-use Android app to add missing information). I couldn't find data for all my questions and some were not up to date, but I found a few starting points on how to do it myself[2][3]. Soon I realized that many more interesting questions about OpenStreetMap in general could be answered with the data and I created a website (https://piebro.github.io/openstreetmap-statistics/) to show them. Since I want the data to be up to date, I added a…

When Google forced the switch from UA to GA4, I found myself struggling to understand my magazine's performance metrics (I occasionally edit a magazine along with my full-time job). So I built a dashboard that pulls GA4 data and presents it in a clean, intuitive interface focused on metrics that actually matter. It made the job of pulling reports and usage stats very simple for my website and greatly improved my daily productivity. At this stage, it was running on localhost on my machine and during this project, I ended up learning React (coming from a pure C/C++ world). I showed it to…

This was my recent weekend project, aimed at teaching me JavaScript, a bit of HTML5, and (mostly) WebGL. The orbital data are from NASA JPL. I was inspired in part by this Flash app: http://www.dynamicdiagrams.com/wp-content/uploads/2011/04/orrery_2011_bce.swf, but wanted to do something in 3D. Coming from the games-dev world, this is my first introduction to web coding. The UI is jquery. I mostly used http://learningwebgl.com/blog for the 3D stuff. Being WebGL, it will work mostly on Chrome, Firefox 4 Beta. Forget about IE. I needed to figure out how to render text to the WebGL canvas - I…

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

Hello HN! These last few months I've been working on my first open source project: an embedded database written in pure-go. That took me some months, as I had to learn how to deal with such large packages. Until then, all packages I had made were quite small an did not require much. I usually did not have to worry about things like allocation optimization and instance pools until This project. It started when I wanted to make a port of a tool to a TUI environment. I'm actually used to working with TUIs in golang, so that was my language of choice. The tool I wanted to port is written in…

I've been building a bunch of US geography tools/games/visualizations and thought folks on HN might like this one. There are also drive-time and bike-time tools available on the same page. For folks interested, all of the data comes from OpenStreetMap and the US Census at the moment - OSM for routing and points interest and the US Census for population data. Anonymous users can use it 5x/day. I put up a waitlist page to gauge interest in a paid version but there's no way for the public to make an account - feel free to bypass the limits in an incognito tab. The site is US-only…

Tokyo Trains▲13Semi inspired by the 3d Shinjuku station that was posted again recently, I noticed it was missing a large portion of the "complex" where "complex" is defined loosly has how far you can walk without stepping outside. So I asked Claude to make a 3d map of all Tokyo Trains, no libraries, and let you zoom into stations, and the first version with both map and the Shinjuku complex was ready in about 3 hours. It spent another 7 or so in various nit picky things I asked for to get to the current version. I know these will only get better but I think the thing I find most interesting is no libraries…

Hey HN, This started as a personal curiosity and Claude helped me build it out. The Quiet Map reads 98 broadband seismometers from around the world every hour. Ground vibration in the 4–14 Hz band is usually done by human activity - traffic, trains, footsteps etc. Each station is compared against its own history at the same hour of day, and the map names the place currently furthest below its own normal: the quietest place on Earth right now. Hope you enjoy it and would love your feedback!

Hey HN. I made a micro site one recent evening to see upcoming (and recent past) timezone transitions. At my job, we have some timezone specific code where we often see spikes in metrics due to random timezone shifts around the world. Just for fun, I wanted a way to easily see where and what this timezone shift might have been, so built this mini site to do so. Its fully clientside and works by making use of the Internationalization API, so if you need an API for this you're coming to the wrong place, but feel free to yoink the code. Its just one fat index.html file. Served off my VPS via…

For the last 6-months, we've been working on a way to offer free access to content that is normally found online. We are now live and broadcasting data to all of North America, Europe, North Africa, and the Middle East (it's an MVP, so a very tiny channel). By October we will be on 7 different satellites and will have full global coverage. The link and video below offers a quick overview on the components and process necessary to receive Outernet's signal. The video in the link shows the user's equipment and system in action. If you already have a Ku-band dish and receiver, you can see our…

Hi HN, Since I was a kid, I have always been fascinated by the flight display screens at the airport wondering where I can fly direct if I had an open ticket There are more than 38 million commercial flights per year departing from +3,200 airports and served by +580 airlines! So much data that can be summarized and made accessible to everyone in an easy and convenient interface. Today, I’m releasing Direct flights, a tool to explore all non-stop flights from any airport: https://direct-flights.com/ # How it's made? The frontend is built on React - using a server-side rendering…
