# Provenance and licences

The visual vocabulary was studied from LemoLab / Lemomo's
[LiDAR Survey style guide](https://github.com/lemomo-ai/lemo-opuscar/tree/main/styles/lidar-survey),
at source revision `3961ddb3d24d8876e0e2754f7790d66908acee51`.
Its documentation describes fixed survey returns, classification peeling,
scan-to-surface transitions, hairline measurements and continuous spatial camera
movement. This package adapts those general principles. The upstream MIT licence
is retained in [UPSTREAM-LICENSE.txt](UPSTREAM-LICENSE.txt).

The reference film remains in the upstream library. Its location, narration,
claims, data, tracings, score, frames and renderer are not redistributed here.

The independent page, Canvas study and preview artwork are original code and
synthetic geometry by Codex Film Studio. They illustrate material and motion,
not a real survey or a validated data-processing pipeline. New production data,
measurements, media and review records belong in external project folders.

Page fonts are self-hosted under SIL Open Font License 1.1: Barlow Condensed Light
by the Barlow Project Authors and IBM Plex Mono by IBM. Files and licence notices
are in `showcase/fonts/`, obtained from the Google Fonts repository. Chinese
characters use the reader's installed fonts; no remote font service is called.
