Adds Microwaveprop.Canopy module that reads 1° × 1° uint8 per-degree
canopy-height tiles (mirrors SRTM .hgt naming/layout, 30 m resolution).
Returns 0 m for areas with no tile on disk so the lookup is safe to
thread through the existing path-clearance pipeline before any data
lands.
Wires canopy into:
- PathTerrain.obstacle_top: per-sample blocker = ground +
max(building_m, canopy_m), so the rover ranks paths through forests
as obstructed even when no buildings sit on the line
- CandidateDetail profile: each sample now carries canopy_m alongside
building_m
- Rover-detail SVG: green "trees" polygon stacked on terrain, under
the red building polygon
- Path calculator elevation chart: green Tree Canopy dataset between
terrain and buildings
Data prep (download Potapov 2019 / Lang 2022 GeoTIFF, slice to per-degree
uint8 tiles, drop in /data/canopy/) is a separate one-shot operation —
without tiles, lookups return 0 and the existing behavior is unchanged.
Path calculator now queries Microsoft Building Footprints for the
tallest structure within 80m of each profile sample and renders a red
"Buildings" dataset on top of the terrain layer in the elevation chart.
Also normalize on-disk grid HRRR cells to include the legacy
:min_refractivity_gradient / :surface_refractivity / :ducting_detected
keys (mapped from :native_min_gradient and :duct_count). Path-calculator
crashed in prod with KeyError when a path's HRRR points came from the
new on-disk grid format instead of the DB profile shape.
Three improvements to the contact detail page:
* Track async hydration per source in `hydration_pending` so the
Terrain / Soundings / Atmospheric Profile sections render a loading
spinner while their task is in-flight instead of briefly flashing
"no data available" before the payload arrives.
* Propagation analysis summary now names the origin station by
callsign ("Path is terrain-obstructed at N mi from W5XD") instead
of the generic "station 1" placeholder.
* Elevation profile chart labels the 0-mi and max-mi ticks with the
matching callsign so it's obvious which end of the profile is
which station.
- Rename all .js files to .ts in assets/js/
- Add interfaces for hook state, data structures, and event payloads
- Add type annotations to function parameters and return types
- Create type declarations for vendor deps (Leaflet, Chart.js, Phoenix, topbar)
- Update tsconfig.json for strict TypeScript checking
- Update esbuild entry point to app.ts
