PowerOutage.us is an ongoing project created to track, record, and aggregate power outages across the United States. This site has tracked some major events, including hurricanes, grid failures, and other weather events. You can view some detailed information about them here.

Data is updated site wide approximately every ten minutes.
They have a REST API but there is no free tier.
Most people find this website because they are disturbed by an unusual unidentified low-frequency sound that scientists now call the Worldwide Hum. The classic description is that The Hum sounds like a car or truck engine idling outside your home or down the block. Some people describe it as a low rumbling or droning sound. It is typically perceived louder at night than during the day, and louder indoors than outdoors. The sound can usually be masked by background noise, such as a fan or keeping the radio on. We estimate that 2-4% of the global population can experience this phenomenon under certain conditions.
The typical characteristics of the World Hum are that sufferers hear it wherever they go, and that other people in the same place and time cannot hear it. This may be a type of otoacoustic phenomenon generated internally in the brain and auditory organs, through mechanisms which are not yet fully understood, but for which this project tries to find answers and possible remedies.
The entire dataset can be downloaded as a CSV file. There is also a project whitepaper for people to gather more data for analysis.
We offer several resources here relating to over-the-air (OTA) broadcast services (TV, FM, and others). We have a variety of online tools, downloadable content, reference information, and discussion forums to help users learn, understand, and make informed decisions about the OTA services available to them.
The Signal Analysis Tool lets you enter a location by address or by coordinate, and optionally the height of an antenna above ground. It then runs 3D propagation models for the exact location and height and generates a "radar plot" report that summarizes the signal strength and direction of all the channels in the area.
A collection of several hundred online tools for OSINT.
A project that uses your browser's Web USB API, an RTL-SDR dongle and antenna, and some vanilla JS code to implement an ADSB tracker without a dedicated server. Doesn't use a web design framework so you can check it out and throw a web server (like http.server) on it, and there you go.
Headway is a maps stack in a box that makes it easy to take your location data into your own hands. With just a few commands you can bring up your own fully functional maps server. This includes a frontend, basemap, geocoder and routing engine. Over 200 different cities are currently supported.
Headway is currently capable of showing a map, searching for points of interest and addresses within an OpenStreetMap extract and providing directions between any two places within that extract. Supported modes include driving, cycling and walking. Transit directions are a work-in-progress.
Many aircraft broadcast information about how accurate their navigation system, which is almost always GPS, is at any given moment. The GPSJam map aggregates that data over 24 hours in time bins it into a hexagonal map. Green hexagons show where more than 98% of all aircraft who flew through that area reported good navigation accuracy. Yellow hexagons show where between 2% and 10% of aircraft reported low navigation accuracy. Red hexagons show where more than 10% of aircraft reported low navigation accuracy.
Data is pulled from ADSB Exchange.
Open Infrastructure Map is a view of the world's infrastructure mapped in the OpenStreetMap database. This data isn't exposed on the default OSM map, so I built Open Infrastructure Map to visualise it. If you want to edit the data and you're new to OpenStreetMap, check out learnOSM.
If you already have some OSM experience and want to start tagging infrastructure things, take a look at the tagging guidelines for power and telecoms.
Sometimes called pregnancy resource centers or crisis pregnancy centers (CPCs), fake clinics do NOT provide comprehensive reproductive health care—or much of any "health care" at all! Instead, they use phony ads to trick pregnant people into making an appointment, promising “free ultrasounds” or “pregnancy support.” Once inside, people are lied to, shamed, and pressured about their reproductive health decisions, often delaying their procedure or pushing them past the deadline for a legal abortion altogether.
Fake clinics are often made to look like medical facilities, yet they don't practice medicine (outside of an occasional ultrasound or STI test), nor do they use medical facts or standardized ethics. More and more, these predatory places are funded by taxpayer dollars, impacting poor women and people of color the hardest.
skies-adsb is a virtual plane spotting progressive web app / virtual aquarium (with aircraft instead of fish) / interactive real-time simulation. Aircraft are tracked via unfiltered ADS-B transponder data in real-time and rendered in 3D. The ADS-B data source is meant to be a RTL-SDR receiver connected to a Raspberry Pi running on your home network. Flight status data is provided by the FlightAware AeroAPI v2. The aircraft photos are provided by Planespotters.net.
Scripts and stuff for manipulating the json files generated by FlightAware's version of dump1090. Mostly command line and ncurses.
A small set of Python functions to draw pretty maps from OpenStreetMap data. Based on osmnx, matplotlib and shapely libraries.
A cross-platform, user-friendly free software application for social network analysis and visualization. Draw social networks with a few clicks on a virtual canvas, load field data from a file in a supported format. Edit actors and ties through point-and-click, analyse graph and social network properties, produce beautiful HTML reports and embed visualization layouts to the network.
Seems to be a general-purpose mapping server of some kind.
Waarzitje.nu is a basic application for submitting and retrieving live location updates. Originally focused on OsmAnd, but basically any application that supports REST could use it.
The back-end (REST API) of this application is made with Go, the front-end mapping interface is made with modern Vue 3 and TypeScript. Because of its modular setup, it is possible to run only the back-end, only the front-end or a combination of both.
Map Maker is a powerful but easy-to-use Web application for creating custom maps. You can upload your data, customize how the data is visualized, then export the map or share it with others for editing. Bulk import, filtering, geocoding, custom icons.
A wholly unnecessary replacement for Dump1090's web interface for tracking ADS-B equipped aircraft.
The OpenAQ Community harmonizes disparate air quality data from across the world so that citizens and organizations can fight air inequality more efficiently. The data is captured from multiple sources and made accessible to all through our open-source platform.

tfviz analyzes Terraform deployment files and generates maps which depict what it's going to do in production. Right now it only works with AWS environments.
