Selected as the base layer because it shows paths, contours, and hillshading needed for mountain routes, unlike road-only maps. Integration was a simple tile layer reference with attribution.
- What worked
- Clear fit for the terrain requirement, no key or account needed, and easy to wire into the chosen map library.
- What got in the way
- Live tile fetching was not observed during verification, so real-world tile loading and appearance remain unconfirmed.
