550x350 m clipped to the block, already in the project CRS, 984 KB, committed
through LFS. Verified against the service's own point query and the earlier
probe: 115.911/119.422/117.593 m, agreement within 6 cm.
Adds Geo/scripts/dem_stats.py, a stdlib tiled-TIFF reader, because GDAL cannot
run on the host and the exported raster is tiled rather than strip-organised.
QGIS stable is 4.2.3 on the current KDE runtime; the stale 3.28.9 lts install
stays flagged for removal. PROJ 9.9.0 from that flatpak turns the recorded
origin into E 376515.389 / N 3774224.083 (NAD83 UTM 11N), with six control
points whose projected spans reproduce the OSM footprint measurements. Engine
decision recorded: 5.8.4 is downloading, 5.2.0 stays only as a fallback.
New Geo/scripts/street_profile.py measures the 279.4 m block centreline, the
three signalised crossings (20.9-25.9 m across), sidewalk centrelines at 12.6 m
and 13.6 m, and per-building setbacks of 13.0-15.8 m. Derived sidewalk widths
of ~4.0 m south and ~5.3 m north cross-check against the mapped centrelines.
Geo/manifests/local-origin.md fixes EPSG:26911 and the Highland intersection
node as origin, defines the axes and the x100 metre-to-centimetre rule, and
leaves the projected pair blank because PROJ is not installed here.
Records the lane-count discrepancy (4 tagged lanes over a 20.9 m carriageway).
Inventory the sibling security-game project and copy only the evidence: nine
licensed photos with their sidecar provenance into Art/reference/hollywood/,
now LFS-tracked. Add the block-wide OSM extract with a manifest, resolve the
demo bounds (Orange Dr -118.341434 .. Highland Ave -118.338718, 279 m) and the
south/north building sets, and add Geo/scripts/block_report.py to reproduce it.
The sibling docs place the El Capitan Theatre west of 6840; OSM geometry and
the house numbering put it east. Recorded with the two unresolved measurement
conflicts rather than averaged.
