Drop the OpenStreetMap/ODbL attribution requirement, the Google imagery rule, and the related F-4 requirement, risk R-4, release check, and TODO items across AGENTS, PLAN, ROADMAP, README, setup, architecture sections, and manifests. OSM data is now documented as local private use only. Also normalize numbered-list indentation in the architecture docs.

# OSM extract — Hollywood Blvd block, 2026-11-06
|
||
|
||
| Field | Value |
|
||
| --- | --- |
|
||
| Source | OpenStreetMap API v0.6, `map` endpoint (`api.openstreetmap.org`) |
|
||
| Extract date | 2026-11-06 21:45 CET |
|
||
| URL | `https://api.openstreetmap.org/api/0.6/map?bbox=-118.3435,34.1000,-118.3365,34.1030` |
|
||
| Data timestamp | not reported by this endpoint; the response carries no replication timestamp, so the extract date is the only date available |
|
||
| Bounds | west −118.3435, south 34.1000, east −118.3365, north 34.1030 (WGS84) |
|
||
| Extent | ≈ 640 m east–west × 333 m north–south |
|
||
| Contents | 3565 nodes, 350 ways; streets: Hollywood Blvd (`secondary`), North Highland Ave (`primary`), North Orange Dr, North McCadden Pl, North Sycamore Ave, Hawthorn Ave, Walk of Fame footway, service alleys |
|
||
| File | `Geo/raw/osm-api-map-2026-11-06.osm` (1.66 MB, XML) |
|
||
| SHA-256 | `64615f0db4715c2d50860052e300930c201bbb87e183a1de5985f2d99d83f4e4` |
|
||
| CRS in source | EPSG:4326 (WGS84 lat/lon) |
|
||
| Local CRS and origin | not yet chosen. Candidate EPSG:26911 (NAD83 / UTM zone 11N); origin to be recorded when the QGIS step runs |
|
||
|
||
## Why this bbox
|
||
|
||
It contains the demo block from Highland Avenue to Orange Drive plus the whole north side within 50 m, with enough margin to include the streets' intersection nodes and the alley network behind the south frontage. It deliberately excludes the rest of the boulevard: larger extracts cost processing time.
|
||
|
||
## Coverage limits
|
||
|
||
- Building interiors, heights above the tagged value, and pavement widths are not in this data. Treat all of it as layout.
|
||
- The `height` tag exists on some buildings and is absent on others (`6838` has only `building:levels`, `6922` has neither). A missing tag is not a zero height.
|
||
- The extract has no elevation. The DEM decision is still open; see `ROADMAP.md`.
