Aerial imagery: Google Earth, and the imagery providers credited on screen in the film.
A course with no hills is a course with no feedback. Berlin’s boulevards are wide enough to run ten seconds a kilometre too fast without noticing, and nothing on the road says so until km 30.

| Berlin LoD2 city model (LoD2-DE Berlin, CityGML)Geoportal Berlin / Senatsverwaltung für Stadtentwicklung, Bauen und Wohnen · City | Buildings | LoD2 - modelled roof forms, no facade texture | Datenlizenz Deutschland - Zero - Version 2.0 (dl-de/zero-2-0)Zero-2-0 waives attribution as a legal condition; we credit Geoportal Berlin anyway.The source CityGML carries no ParameterizedTexture at all - the buildings are untextured by design, which is why facades are procedural and the orthophoto is projected top-down only. Six 1 km tiles cover the Phase 1 scene block. | Cleared | |
| Berlin true orthophoto 20 cm (truedop_2023)Geoportal Berlin · City | Imagery | 20cm/px | Datenlizenz Deutschland - Zero - Version 2.0 (dl-de/zero-2-0)Attribution is not a legal condition; we credit Geoportal Berlin anyway.This is the ground texture for every low pass: a true orthophoto, so building lean is already removed. It is projected top-down onto ground and roofs only; nadir imagery holds no facade data. The vintage is part of the layer rather than a detail of it. Berlin serves each flight as its own WMS layer, 2023 is the one every frame is drawn from, and it was chosen for the season: it is the only leaf-on flight, and the sun in the renders is solved against the light already baked into it. A later vintage is a different photograph of a different summer, so the credit names the year.

| ATKIS DGM1 - Digitales Geländemodell Berlin, 1 mGeoportal Berlin / Senatsverwaltung für Stadtentwicklung · City | Terrain | 1 m grid | Datenlizenz Deutschland - Zero - Version 2.0 (dl-de/zero-2-0)The reason a Berlin elevation profile is possible at all.This is a DGM, a bare-earth model, defined by its own abstract as excluding vegetation and buildings, where Copernicus GLO-30 is a DSM and carries every rooftop: sampled off that global model the same course reads 197 m of gain, most of it architecture. Sampled through the queryable layer c_dgm1, whose GetFeatureInfo returns a height in metres above NHN. Two things about the number that matter more than the source. Unsmoothed, even this bare-earth series sums to 115 m of gain at 50 m spacing, because at that spacing it is a picture of kerbs and ramps rather than of the ground, which is why the published 35.9 m is quoted with its 1 km smoothing window and its 200 m spacing. And a bare-earth model reads the ground UNDER a bridge, not the deck a runner is on, so canal and Spree crossings sit up to 5 m low in the raw series.
