Radiation map

[pragamichele]

Merges a Geiger counter data log with a GPS track and produces a map of the route coloured by dose rate, a time chart, and an exportable image.

Single page, no installation, no server: everything runs in the browser and your files are never uploaded anywhere.
Why

Cheap Geiger counters record when they measured, not where. Phones record where you went but not the radiation. This tool aligns the two recordings on their timestamps and reconstructs a georeferenced survey — no extra hardware.

How to use it
Record with the counter's data log enabled (1 second recommended).
Track your route with any GPX app — GPSLogger, OpenTracks, OsmAnd. Set the distance filter to zero, otherwise the phone stops logging points while you stand still.
Download the data log as CSV.
Open the page, load both files, press Auto for the time alignment, then Generate map.
