LSE is the third of the three, beside lumbridge-compute and lumbridge-bench: a 3D engine for walkable places. This first commit is the outside of the world — San Francisco — plus the seams the inside will attach to. The engine renders a City and a list of Markers and knows nothing else. It does not know markers are usually companies and it will never learn that "rejected" is red; that mapping lives in an adapter. Which is what lets one renderer serve a private map, a public one, and a self-hoster with no Lumbridge account, none of them a fork of the others. Three things were designed around the licence rather than discovered after it, because each one is a promise Apache 2.0 makes that is easy to break by accident. No trademarks in the repo — logos are fetched at runtime, and public/logos/ is gitignored. No OpenStreetMap-derived coordinates, which is why every coastline in cities/sf.ts was traced by hand: Nominatim output is ODbL, share-alike, and would attach to the whole pack. And no FlightRadar24 client — their terms forbid scraping and redistribution, so flights are an interface with a simulator and open community ADS-B behind it. The privacy constraint and the licence constraint turned out to want the same thing. Geocoded company positions and pipeline status both stay behind Workie's API; the open repo holds the city and the renderer. The tempting shortcut — commit an sf-companies.json — breaks both at once. Ported out of Workie, where a 3D city engine had no business living. Workie's /live is deleted rather than deprecated. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

ORIGIN AND ORIGINALITY
|
|
----------------------
|
|
|
|
LSE'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. LSE'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 LSE'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 LSE 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

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.
