ORIGIN AND ORIGINALITY
----------------------

Tera's city view was inspired by the interaction model of two prior works —
Levels.fyi Atlas, and Nutlope's NYC AI Atlas (https://github.com/Nutlope/
nyc-ai-atlas), which itself credits Levels.fyi. What was taken is the *idea*:
a left-hand chapter legend, animated camera flights into map areas, clickable
place labels, and ambient motion in the scene.

No code, geometry, or asset from either work is present here. Tera's renderer,
its terrain system, its block-lattice building placement, and every coordinate
in every city pack were written from scratch. The two projects do not even
share a subject: the NYC atlas renders hand-traced Manhattan on flat ground,
and Tera's premise is relief — a city you cannot read without its section.

Stating this plainly matters, because at the time of writing the NYC AI Atlas
repository carries no LICENSE file. Absent a licence grant, the default is that
no rights are given, so nothing from it could have been reused even had we
wanted to. Attribution here is courtesy toward a good idea, not a licence
obligation.


GEOGRAPHIC DATA
---------------

All geography in src/cities/ is original expression, traced by hand.

It is deliberately NOT derived from OpenStreetMap. OSM data — including
coordinates returned by Nominatim geocoding — is licensed under the Open
Database License (ODbL), whose share-alike terms would attach to any derivative
database and cannot be reconciled with the permissive licence above.

Where real elevation data is used in future, it will come from USGS/SRTM
sources, which are United States government works in the public domain.


TRADEMARKS
----------

This repository contains no third-party logos, wordmarks, or brand assets.

Organisation logos displayed by applications built on Tera are fetched at
runtime and are never redistributed as part of this project. All trademarks,
service marks, and trade names are the property of their respective owners.
Any use is nominative — to identify the organisation referred to — and does not
imply affiliation with or endorsement by the trademark holder.

Build tooling (Vite, TypeScript, esbuild) is a development dependency only and

AIRCRAFT DATA
-------------

The flight sources shipped in this repository are a simulator (original work)
and clients for open community ADS-B feeds. No commercial aviation data
provider's data is included or redistributed, and no client for a provider
whose terms prohibit such use is present.
