Thermal detections in Noord-Holland
Events are grouped by what the satellites can and cannot currently say. A quiet observation is not a safety assessment, and an unconfirmed one is not an all-clear.

Where the measurements are
Drawn server-side from the public event read model. Every mark is a measurement: nothing here is interpolated, smoothed or inferred.
What each mark means
- VIIRS (NASA)375 m—
No detections stored for this frame.
- Meteosat (EUMETSAT)≈2 km—
Measures how much energy is radiated, which is what sizes the glow. Its individual pixel positions are not stored, so no Meteosat footprint is drawn — inferring one from the sharper layer would put a detection pixel on ground nobody measured.
- True geographic scale, corrected for latitude. Frame is about 246 km across.
- At this scale both sensor footprints are smaller than a pixel, so no true-scale square is drawn. Two squares clamped to the same legible minimum would show a 1:1 ratio for a 5:1 fact.
- The glow means “an event, roughly here”. Its area follows the measured power and its radius is capped, because an uncapped one would assert a burnt extent nobody measured. The number carries the magnitude.
- Grey is what a later pass has superseded. Colour means the most recent sharp measurement, and it never fades with the clock — only newer knowledge demotes it.
- At country scale each event is one glow. Individual 375 m detections resolve on the event page, where they are larger than a pixel.

Tracked events without measurable activity in the latest observation
No satellite detection does not mean an area is safe. Cloud, sensor timing and heat below a sensor’s threshold can hide activity.
