A runway is one line and two fractions
How Chronotopia stores a runway's whole history as one centreline with dated phases, grows it smoothly between them, and hatches the part that is only planned.
Places & history
How Chronotopia rebuilds places year by year, starting with the airports of Barcelona–El Prat, Ibiza and Palma de Mallorca: where the dates and the shapes of each stage come from, what the ≈ badge on so many of them means, and how planned works are shown without pretending they are built.
Also how the model itself is made, from the ground under each airport to its runways, the aircraft that fly in each year and a terminal modelled in the middle of its remodel, how the Sagrada Família is being built from Gaudí's own surfaces and checked against photographs, and what each part gets wrong.

Dating airport buildings from old aerial photos
How Chronotopia gives a year to thousands of buildings, aprons and taxiways that no document dates: aerial photos, the gaps between them, and what ≈ really means.
Laying an airport on real ground with the IGN terrain model
How Chronotopia turns Spain's 25 m terrain model into ground under El Prat and Ibiza: a levelled platform, a coast that meets the map, and buildings standing on it.
Introducing Chronotopia: El Prat and Ibiza, rebuilt year by year
Chronotopia rebuilds Barcelona–El Prat from 1916 and Ibiza from 1936 in 3D, one year at a time, with a source behind every event. What it shows and what it can't.
