Sdr Heatmaps

RTL-SDR heatmaps and some web visualisation tools

SDR Heatmaps

This repo will host high resolution radio heatmaps that can be easily viewed in a browser.

The key is to use the Deep Zoom technology to generate tiles which would display only the visible parts of an image. It's similar to how Google Maps allows us to view all the world in a browser.


  1. Fork this repo and make a local clone
  2. Copy your high resolution heatmap in the highrez directory
  3. Edit maps.json and follow the example which is already in place
  4. Run to generate the tiles, the .dzi images and .html files
  5. Commit, push and submit pull request :)

If you can help identify some of the signals here let us know so we extend the description.
