• Aerial imagery: © Geodetický a kartografický ústav Bratislava (GKÚ), Národné lesnícke centrum (NLC), CC BY 4.0. Official WMS and reuse terms. Downloaded geographic crops of the published 2023–2025 orthophoto cycle; no retouching. Used on terrain and simplified roofs.
• Elevation: Mapterhorn Terrarium tiles, Slovakia DMR 5.0 © ÚGKK SR. Provider attribution and source licenses. Decoded numeric elevations and resampled onto a 4 m grid. Vertical relief is not exaggerated.

The source manifest records URLs, acquisition times, checksums, image dimensions and geographic bounds. Inputs were retrieved on 22 September 2026. Coordinates use a WGS84 ECEF tangent plane centred on 18.325° E, 49.124° N.

Modifications: cropping and polygon clipping; projection to local metres; terrain interpolation; footprint extrusion; estimated road widths, bridge decks and building heights where source measurements are absent; deterministic tree inference from aerial imagery. Facades are illustrative and roofs simplified. This is a navigable visualization, not a surveyed architectural model.
