Coverage Critic Map – Combined Coverage Map for US Cell Networks
Hi HN! I built a map that shows cell coverage from the major US networks. It draws primarily on data from the FCC, but that's supplemented/calibrated with a bunch of crowdsourced data from the DIMO project (dimo.zone). My goal is to make comparisons between networks super easy--one click to toggle between networks or technologies. I'm never sure how much to trust networks' self-published maps. I'm still in the early days of incorporating the crowdsourced data, but I'm hoping all the on-the-ground data can lead to a map that's more reliable than network operators' maps (those are largely…

A website that heatmaps your city based on your housing preferences2025 · theretowhere.com · ▲321For the past few months, I've been working on a website that answers two different questions: - Where in my city have the best travel times to all the things and people I care about? - Given a listing, how far is it from all the things and people I care about? Personally this was fueled by my own frustrations when I was apartment hunting in NYC. I was frustrating to have to juggle so many Google Maps tabs when I was evaluating a listing, and it was also annoying to not have full confidence that I was even searching in the right places. I wanted to be close to work, a Trader Joe's, and a…

- TTText to 3D simulation on a map (does history pretty well)2025 · mused.com · ▲72
Simulate anything on a map from a text prompt -- and conduct risk analysis against LiveUA map's global realtime data points from social media and news sources. I trained a GPT-2-size model on historical incident data used to predict things that will go wrong. As historian Benjamin Breen mentions, the leading language models are good historians, so the application will simulate historical events pretty well also. I include a Multi-Agent RL Urban Mobility model in progress displayed on the map as small white cubes representing traffic and pedestrians. Around SF, it uses real census data and…
- SHSelf-Hosted Maps Stack2022 · maps.ellenhp.me · ▲213
Over the past week I built a project to let people self-host an entire maps stack so they don't have to send data to the big G. Right now it includes a base map, geocoder and directions server. Currently only bicycle directions are supported, and I'm only hosting tiles for Seattle because I'm unemployed and can't afford to host data for the whole planet. Check it out! https://maps.ellenhp.me/ https://github.com/ellenhp/headway Ultimately I'd like to really focus on transit routing (not implemented) but I'll probably throw a driving mode in there too.
