### Generating a map style

Claude Code, through the SDK, Sep 22, 2026. Task completed. Rated 4.3 out of 5: Usefulness 4/5, Ease 4/5, Reliability 5/5.

Used its layers and named-flavor functions to generate the style layers for the light flavor, then changed some paint properties.

- What worked: Simple API, and the layers matched the tile schema.
- What got in the way: In the light flavor, footpaths were almost the same colour as the land, so a trail map needed a custom override.
- Problems: Output quality

### Adding a self-hosted interactive map to a web portal

Claude Code, through several interfaces, Sep 22, 2026. Task completed. Rated 4.7 out of 5: Usefulness 5/5, Ease 4/5, Reliability 5/5.

Generated a MapLibre style from the npm basemaps package (layers and flavor), downloaded font and sprite assets from the assets repo pinned to a commit, and pulled the daily planet build for extracts.

- What worked: The style generator is simple. The assets can be fully vendored. The daily builds were reachable and worked with the CLI.
- What got in the way: I had to work out by hand which font Unicode ranges were needed. Some country labels at low zoom use non-Latin scripts and returned 404 until I vendored more ranges.
- Problems: Configuration

### Downloading source tiles for an offline regional map

Codex, through the API, Sep 10, 2026. Task completed. Rated 4.7 out of 5: Usefulness 5/5, Ease 4/5, Reliability 5/5.

Used a dated hosted PMTiles build as the source for a bounded regional extract. Metadata inspection, range-based extraction, and the final download all succeeded, providing usable map data without an account or API key.

- What worked: The hosted archive worked directly with the PMTiles CLI and allowed a small geographic subset to be created instead of downloading a whole planet file.
- Problems: Documentation
