Store art and trailer

These files are on the store page, not in the app. dav3studios made them from the app's own scenes. The material of others in those scenes is credited under the table.

What Files Made by Licence How it was made
EpochWise store art and screenshots. The covers, hero, mini landscape, icon, trailer cover, transparent logo and spatialized icon show Halley's Comet over the ridge at Battle in April 1066, rendered from the app's own halley_1066 scene (tools/store/store_art.py), with the title in Atkinson Hyperlegible Bold (SIL OFL 1.1, in the app). The 8 screenshots in store/art/screenshots/ are the app's own autoshots at 2560 x 1440 (tools/store/store_shots.sh). The terrain of the scenes is survey data of the Environment Agency, Ordnance Survey (OGL v3) and IGN (Licence Ouverte 2.0), credited on the credits page (docs/store/credits_page.md). For the store only, not in the app. store/art/*.png dav3studios made by dav3studios, with the third-party material below tools/store/store_art.py
EpochWise store trailer: recorded with Godot's Movie Maker from the app's own scenes (tools/store/trailer.gd), with the app's own narration voice and music and the CC0 sounds of the scenes. Every sound under CC BY is left out. The terrain and the sounds of others in it are credited on the credits page (docs/store/credits_page.md). For the store only, not in the app. store/art/trailer_*.mp4 dav3studios made by dav3studios, with the third-party material below tools/store/make_trailer.py
The Data Use Checkup pictures and the crop preview of the universal basic asset store/art/duc/*.png, store/art/review/* dav3studios made by dav3studios, with the third-party material below tools/store/duc_shots.sh

Third-party material in the store art and the trailer

The store art and the trailer show the app's own scenes, so they hold the same third-party material as those scenes. These rows credit it with its licence. The trailer leaves out every sound whose licence asks for credit (CC BY).

Our own work

Everything else in the app is our own work: the code, the scenes, the reconstructions, the narration and voice clips (made with the computer voice Kokoro-82M, no person recorded them) and the music (made by a computer program). dav3studios made them.
