- Toggle button for Maidenhead grid overlay (on by default)
- Coverage candidates now at 0.25° resolution (~28 km) instead of
2°×1° Maidenhead grids, matching HRRR propagation grid density
- Coverage rectangles render as 0.25° cells for finer detail
- Grid overlay is separate from coverage coloring
- Extract scoring logic to Microwaveprop.Rover.Coverage for testability
- Two-phase computation: fast pass (distance + propagation) for all grids,
then SRTM terrain analysis for top 20 candidates only
- Cap search radius to 300 km to keep candidate count reasonable
- Run terrain analysis in Task with rescue/fallback for resilience
- Background Task doesn't block LiveView process
- 5 tests covering: ranked results, empty inputs, station details,
band range differences, field presence
Interactive map-based tool for planning rover operating positions.
Rovers enter stationary stations they want to work, then click the
map to evaluate candidate operating grids.
Features:
- Add stationary stations by callsign or grid square
- Click map to add operating positions (snaps to Maidenhead grid)
- Async SRTM terrain analysis: each stop computes terrain profile
to every station, shows CLEAR/BLOCKED verdict + diffraction loss
- Terrain lines on map: green=workable, red=blocked, dashed=marginal
- Propagation score and 18-hour forecast sparkline per stop
- Route summary: driving distance, unique grid-station pairs
- Band selector affects range limits and propagation scores
- Numbered waypoint markers with score-colored backgrounds
New files:
- Geo module (shared haversine/bearing, used by PathLive too)
- RoverLive with fullscreen map + sidebar
- RoverMap JS hook with grid overlay, station/stop markers, route line
- Nav links in header and map control panel
LiveView page for analyzing microwave propagation between two points.
Features:
- Source/destination input: callsign (via gridmap.org API) or Maidenhead grid
- Band selector for all 8 microwave bands (10-241 GHz)
- Leaflet map showing path line (reuses ContactMap hook)
- Terrain elevation cross-section (reuses ElevationProfile hook)
- Link summary: distance, bearing, terrain verdict
- Loss budget: FSPL + O2 + H2O + rain + diffraction
- Propagation score with 10-factor breakdown
- Current atmospheric conditions from path-integrated HRRR
New CallsignClient for gridmap.org location lookup.
Navigation links added to main navbar and map control panel.
Contact scoring now uses all HRRR profiles along the path instead of
just pos1. Aggregation strategy:
- Best along path for beneficial factors (refractivity, pressure)
- Worst along path for harmful factors (rain, wind)
- Average for neutral factors (temp, dewpoint, PWAT, BL depth)
Scorer.path_integrated_conditions/2 merges multiple profiles into a
single conditions map. Falls back gracefully to single-profile scoring
when only one profile is available.
Apply 5-point circular moving average to reach_km values before
rendering the boundary polygon. Eliminates sharp spikes caused by
isolated terrain anomalies in SRTM data.
Runs BackfillEnqueueWorker every 30 minutes to pick up contacts with
pending/queued/failed enrichment status and enqueue missing jobs.
Before enqueueing, reconciles terrain contacts stuck in "queued" by
checking the terrain_profiles FK directly.
When ASOS/RAOB/IEMRE APIs return empty data, store a stub record so
dedup checks (has_surface_observations?, has_sounding?, has_iemre_observation?)
see coverage and don't recreate the same jobs on future backfill runs.
Queued contacts just need reconciliation (check if data exists),
while pending contacts need actual HRRR fetches. Process pending
first so real work happens before reconciliation.
Backfill dashboard now has checkboxes to select which enrichment types
to process (HRRR, Weather, Terrain, IEMRE). Prevents weather jobs from
flooding the queue when only HRRR needs work.
The propagation grid stores profiles at 0.125° intervals, so contacts
up to 0.0625° from a grid point would miss with the old 0.05° tolerance.
This caused has_hrrr_profile? and find_nearest_hrrr to fail matching
against existing data, leaving contacts incorrectly stuck as pending.
enqueue_for_contact unconditionally marked contacts as :queued even
when no HRRR jobs were needed (profiles already exist). Workers never
updated contact status to :complete after storing profiles. Contacts
got stuck and were never re-processed.
- Mark :complete when no jobs generated (data already exists)
- Include :queued in backfill enrichable states for reconciliation
- libcluster with Kubernetes IP strategy for pod discovery
- RBAC for pod list/get, POD_IP from downward API, shared cookie
- LiveDashboard at /dashboard for all environments
- Fix score_pressure crash on nil pressure_mb (coastal HRRR points)
- Set 10-min timeout on grid score upsert transaction (was :infinity)
- Single DELETE for prune_old_scores instead of N queries in a loop
- Remove dead load_hrrr_refractivity that loaded 95k rows into nil map
- Pass selected_time to point_detail to skip latest_valid_time sub-query
- Batch station existence checks (1 query per path point, not per station)
- Batch solar index upserts via insert_all in chunks of 500
- Batch backfill_distances via single UPDATE FROM VALUES statement
- Add is_grid_point boolean + partial index to hrrr_profiles (replaces
non-sargable modular arithmetic filter on every weather map query)
- Add partial index on contacts(qso_timestamp) WHERE pos1 IS NOT NULL
- Move backfill enqueue to Oban worker so UI returns immediately
Removed n_live_tup > 0 filter that hid tables when pg_stats reports 0 rows
during VACUUM. Added dead tuple column with warning highlight to monitor
vacuum progress. Also includes Styler reformatting and unused dep cleanup.
ON CONFLICT now only replaces score/factors when the score actually changed,
avoiding dead tuple generation for the ~80% of grid points that don't change
between consecutive HRRR runs.
Migration sets aggressive autovacuum on propagation_scores: zero cost delay,
2000 cost limit, 1% scale factor. The table was at 72GB with 108M dead rows
because default autovacuum couldn't keep pace with 14M upserts per hour.
- Only deduplicate against active jobs (available/scheduled/executing/
retryable), not completed ones. Completed jobs no longer block new
inserts for the same args.
- Period reduced from 3600s to 300s
- Fixes contacts stuck in :queued with no actual Oban jobs
- Database triggers on contacts and oban_jobs fire pg_notify on
status/state changes
- RepoListener GenServer subscribes via Postgrex.Notifications and
broadcasts to PubSub
- Backfill dashboard subscribes to PubSub instead of 2-second polling
- Eliminates periodic SELECT queries, updates arrive instantly
- SolarIndexWorker accepts date arg for specific date fetch
- Contact show page enqueues solar fetch when data missing
- PubSub broadcast on solar data arrival, live-updates page
- Spinner shown while fetching
- Migration renames table, column, all indexes, and FK constraints
- Contact schema now references "contacts" table
- TerrainProfile foreign key renamed from qso_id to contact_id
- All code and tests updated to use contact_id
- Radio.ensure_positions!/1 computes pos1/pos2/distance from grids
- Called in contact show page mount and enqueue_for_contact
- Migration backfills positions for existing contacts missing them
- Migration corrects enrichment statuses based on actual data presence
- Backfill dashboard includes contacts with grids but no positions
- New fields: hrrr_status, weather_status, terrain_status, iemre_status
with values: pending, queued, processing, complete, failed, unavailable
- EnrichmentStatus module defines valid state transitions
- Migration backfills: queued=true → complete, false → pending
- Workers set status on transitions (queued on enqueue, complete on finish)
- Show page reads status from contact struct, not computed dynamically
- Backfill dashboard queries status fields for accurate progress counts
- Remove cron-scheduled ContactWeatherEnqueueWorker (enrichment only on
submission, page view, or manual backfill)
- Partial indexes on status != 'complete' for fast unprocessed lookups
