First look
On entry the Bali demo opens on the map: the terrain in three dimensions with satellite imagery, and over it what matters — the concentration layer of one species, coloured by the scale; the wind field that pushes it; and the markers of the sources and receptors.
Reading the map
Section titled “Reading the map”- The markers are dark glass boxes with a symbol. On a receptor, the symbol’s colour is its alert level at this instant: green all clear, amber warning, red alert, purple critical. A source always wears the brand blue: it has no level, only a position. Zooming in opens the marker to show name and value.
- The legend (the Legend panel, open on entry) says which species is being viewed, in which unit, and which concentration each colour of the layer stands for.
- The top bar says what is being viewed: the species, the scenario, the source group, the receptor — and VIEWING, with a chip stating whether the instant shown is PAST, PRESENT or FORECAST.
The timebar
Section titled “The timebar”At the bottom, TIMELINE is a ruler of hours, six-hour marks and days, in the domain’s time zone
(not the browser’s; the zone appears beside the title, as UTC-4). The past already observed is
shaded; hours in which any receptor exceeds a level are tinted in that level’s colour. The pointer
is the instant the map draws.
On entry the view is following the now: the pointer advances minute by minute on its own. To look at another instant, drag the pointer or click the ruler — that stops the following — and the Go to the current time and follow it button resumes it.
Moving through time
Section titled “Moving through time”The Controls panel, from the right rail, has Play and Pause, one step forward or back, to the start or the end, and two map framings. Play animates the forecast: the layer moves with the modelled wind, and markers change colour as they cross a level.
What you see is always one moment of the forecast; time is one of the five dimensions the view can change.
