UpToWhere
The idea came to me after spotting the sea peeking through mountains on a drive near Barcelona. It left me wondering what else was visible from different locations. Some of the features I later added include 3D maps, sun path calculation, adjustable elevation (calculate from a drone/plane POV), and mountain detection. To celebrate the launch, the first 100 HN users can get 1 month of free premium access with the code: UTWfirst100. I’d love your feedback, questions, and suggestions. What would you use this for? What features would you like to see?

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

I really like Stellarium and SkySafari but I felt like these are primarily geared towards exploring the sky but not so much "here are the long list of things I want to see, when can I see them tonight and where". There's also not really a great option I've found that combines sky object planning + location weather details while still being free so I built this. The UI's heavily inspired by NINAs sky atlas + Robinhood. Right now you can: View the altitude chart of objects and 3D view Create lists of objects of interest View the annual max/min daily altitude of an object to find the best…

I made a web app to generate 3D models of real places on earth from land cover and elevation data. Click anywhere on the map to get a polygon, and then click "generate". It should work at most scales, but if your watershed or region selection is too large, the result can be less exciting because it's so flat. As a warning, the 3D models can sometimes be too much for my phone. It's nicer on desktop. I'm still working better on mobile support. The land cover data I'm using gives a cool effect, but at some point I'd like to add in global imagery and clouds. The backend is a Python thread…
Tiny FOSS Compass and Navigation App (<2MB)Jan 2026 · github.com · ▲137Hey HN, This is a follow-up to our original Show HN post, where I launched the first version of MBCompass. https://news.ycombinator.com/item?id=44155741 Since then, I've added several features based on user feedback and community input... I just released v1.1.9 of MBCompass - Minimal, FOSS compass and navigation app. New in this version: - Theme toggling (Dark/Light) controlled via settings - Fix current location arrow visibility - Compass accuracy alerts - Sensor status indicator - Explicit button for showing the GPS current location - Smooth transitions and many more..…

Talanoa▲346Hi 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…
