TERRAIN AND BUILDING LIMITS
Terrain: Mapterhorn elevation tiles via Arnis, using parent resolution where needed.
https://mapterhorn.com/
Land cover: ESA WorldCover 2021 via Arnis.
https://esa-worldcover.org/en
Building footprints come from mapped OSM features. Building heights use OSM
tags where available and Arnis rule-based estimates otherwise. Materials and
forms are a generated representation, not a measured architectural survey.
Terrain is an elevation model, not a surveyed flood datum or clearance measure.
Do not use this world to certify safe flood levels or engineering dimensions.
Structural validation proves file/chunk integrity, not geographic accuracy.
