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 the fire radiates, 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 fire pixel on ground nobody measured.

  • True geographic scale, corrected for latitude. Frame is about 3209 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  • Grey is what a later pass has superseded.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 fire is one glow. Individual 375 m detections resolve on the event page, where they are larger than a pixel.
