The 800 px regional cartograms were rendered from that same database. Administrative levels and feature completeness vary by country; land boundaries do not assert sovereignty.

JSON layout: code, lon, lat, n, h (row-major elevation grid in decimetres); b [render_height,render_min_height,rings], a [layer,class,subclass,rings], l [layer,class,bridge_or_tunnel,polyline]. A ring/polyline alternates easting and southing in metres from the district centre. Only building parts with visible geometry are included. Tagged heights and map-source defaults coexist.
Synthetic: communications, edge points of presence, window and roof treatments, vegetation, vehicles, reconstructed landmark profiles. The scene is not a digital survey and does not show real visitor addresses.
