City illustration, map data & height estimates

The home illustration follows calculated SunCalc sun and moon positions. Its three hill layers use west-to-east maximum surface heights sampled from the reviewed Copernicus grid. The vertical scale is exaggerated for an illustration; houses and Tram28 are decorative, not a surveyed panorama, service status or route. Illustration source and method. Motion can be paused, and reduced-motion preferences are respected.

Map data © OpenStreetMap contributors, under the Open Database Licence. The Protomaps basemap is served by Lisbonline and drawn with MapLibre GL JS (software and data notices); public venue pins retain their source and checked date in the map data.

Sunrise and sunset are build-time astronomical estimates for the fixed Lisbon city centre, calculated with SunCalc 2.0.1 and shown in Lisbon time, including daylight saving. Buildings, hills and cloud cover change what you see. Calculator licence · Solar table and methodology

Height estimates are produced using Copernicus WorldDEM-30 © DLR e.V. 2010-2014 and © Airbus Defence and Space GmbH 2014-2018 provided under COPERNICUS by the European Union and ESA; all rights reserved.

GLO-30 public 2021 data, accessed 16 October 2026, sampled from the native point grid and rounded to whole metres. This is a surface model, including buildings and vegetation, not a street-level ground survey. Net endpoint height changes do not describe every hill, stair or accessible route.
