Changelog

2026-01-14

Talk page auto-preload

Change: Added automatic preload for new talk pages based on subject page category
Reason: Consistent talk page structure without manual setup
Result: Creating Talk:India auto-loads Country template; Talk:Koch Bihar auto-loads Growing Area template, etc.
Dependencies: Requires Template:Talk preload/* subpages to exist

Marker clustering

Change: Added Leaflet.markercluster with worst-status bubble-up
Reason: Overlapping pins at zoomed-out view
Result: Clusters show count + color of worst status inside

Hull boundaries

Change: Added Turf.js auto-generated convex/concave hulls for Growing Areas
Reason: Visual indication of area coverage without manual GeoJSON
Result: Dashed polygons appear at zoom 6-12, colored by worst status

Hull buffer

Change: Added 3km buffer around all hulls
Reason: Linear accession distributions created thin/weird shapes
Result: Capsule-shaped boundaries that look like proper areas

Labels removed

Change: Removed permanent region/area labels, kept hover tooltips only
Reason: Visual clutter with sparse/clustered data
Result: Cleaner map, area info on hover/click

Satellite layer

Change: Added Esri World Imagery as third base layer option
Reason: Useful for seeing actual terrain/cultivation areas
Result: 3-button toggle (basic/terrain/satellite)

CSV URL encoding fix

Change: Added encoding for dashes (-2D) and colons (-3A) in buildCSVUrl()
Reason: Accession IDs with dashes/colons broke SMW CSV export URLs
Result: Maps display pins correctly

Decisions

Auto-generated hulls vs manual GeoJSON (2026-01-13): Chose auto-generated — updates automatically as accessions added, dashed style communicates "approximate"

Interaction-only labels (2026-01-13): Removed permanent labels — too cluttered with sparse data, hover tooltips sufficient

3km hull buffer (2026-01-13): Prevents linear point distributions from creating thin unusable polygons

Talk page preload by category (2026-01-14): JS detects subject page category and loads appropriate template — scales automatically as new page types added
