The Most guide follows the inner main-loop outline to exclude the pit lane. The derived geometry of each of these five circuits retains its stated CC BY-SA licence. It is distributed as machine-readable points in data.json. These licences concern the adapted geometry, separately from the game code, music and rendering. Layouts are game adaptations of the cited data snapshots. Their widths, start positions, scenery, weather and driving scale are not surveyed replicas. Names identify the geographic inspiration; no affiliation or endorsement is implied. 0.9.0: 11 additional arcade layouts were authored for RaceBang. Olomouc is a fictional route inspired by the city tourism map. Kittilä and Poznań deliberately add fictional grade-separated crossings. Reference URLs are preserved in data.json and design/extra-circuits.cjs. Public course titles use towns and countries. Surroundings, seasons and runoff are game interpretations, not surveyed site plans. 0.20.0: Olomouc replaces the earlier original loop with a fictional race route along connected streets of the actual centre. Street coordinates and oriented building footprints: © OpenStreetMap contributors, Open Database Licence (ODbL) 1.0. https://www.openstreetmap.org/copyright — https://opendatacommons.org/licenses/odbl/1-0/ . The derived Olomouc database is distributed in data.json (track key cz-olomouc) under ODbL 1.0. Streets were simplified, uniformly scaled, widened and fitted with tangent circular corners. Rectangular building footprints may be reduced to clear the racing corridor; they retain their mapped centres and orientation. Additional visual reference: City of Olomouc, https://tourism.olomouc.eu/wp-content/uploads/2022/05/mapa-a4-2023.pdf . No city map raster is redistributed. This database licence is separate from the game code and original rendering. 0.21.0: Recommended racing lines in driving-lines.json are derived from simulated clean laps on the attributed circuit geometry. Their mapped geometry retains the applicable licences described above. The Olomouc portion is an ODbL derivative database, © OpenStreetMap contributors. Driving controls, timing search and guide rendering are original RaceBang code. Next version, Monaco surroundings (2026-10-31): building footprints and side-street paths © OpenStreetMap contributors, ODbL 1.0. https://www.openstreetmap.org/copyright https://opendatacommons.org/licenses/odbl/1-0/ Source: https://api.openstreetmap.org/api/0.6/map?bbox=7.413,43.728,7.441,43.746 The derived database in monaco-map.js includes OSM feature IDs, original longitude/latitude coordinates, projected points and the affine projection controls. It is offered under ODbL 1.0. The projection fits the existing arcade course. Decorative footprints are selected to avoid the original driving corridor and physical structures. The racing geometry, collision model, lap timing and saved results are unchanged. Original landmark artwork, boats, people, effects and rendering code are separate from this database. No photographs, logos or map tiles are redistributed.
