Ho Ngoc Hai	d6ac7c316f	feat(industrial): drop non-VN OSM rows + gate sync with country polygon ... The OSM bbox sync was picking up `landuse=industrial` polygons that sit just across the borders in Laos, Thailand, Cambodia and southern China. After the bulk promote we ended up with 220 of those in the public catalog — Vientiane SEZ, Phnom Penh SEZ, Sihanoukville SEZ, several Thai industrial estates etc. Two-part fix: 1. `scripts/data/vn-country-polygon.ts` — a hand-traced ~30-vertex GeoJSON polygon that follows VN's land + sea border. The eastern edge is generous (110°E) so every coastal industrial zone (Vũng Áng / Formosa, Dung Quất, Nhơn Hội, Vũng Tàu / Long Sơn) sits comfortably inside; the western/northern edges trace the actual neighbour borders. Includes a pure-JS `isPointInVietnam(lng, lat)` ray-cast helper for the sync script (no extra dep). 2. `scripts/prune-non-vietnam-osm.ts` — one-shot cleaner. Uses PostGIS `ST_Within(location, polygon)` to delete every OSM row whose centroid falls outside. Verified the polygon doesn't reject genuine VN parks (Formosa Hà Tĩnh, Dung Quất, Nhơn Hội, KCN Đất Đỏ etc. all pass). 3. `sync-osm-industrial-parks.ts` `parseFeature()` now calls `isPointInVietnam` after computing the centroid and bails early on a miss, so the next monthly cron run won't re-import them. Run on dev: removed 220 rows. Final catalog 1,483 KCN, all inside the Vietnam mainland polygon. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-04-30 00:27:37 +07:00
Ho Ngoc Hai	c15bdcc6bf	fix(industrial): improve OSM review UX + public map visibility ... Four UX issues surfaced when reviewing the new OSM-sync pipeline against the actual 2,193 imports — fixed in this commit: 1. Admin queue surfaced noise first. `ListOsmPendingHandler` now sorts by `totalAreaHa DESC` (real KCN first, single-factory `landuse=industrial` polygons last) and accepts `minAreaHa` (default 50 ha) plus a `region` filter. The admin page exposes both as dropdowns — "Tất cả / ≥ 5 / ≥ 50 / ≥ 200 / ≥ 500 ha". Top-of-queue is now Bàu Bàng (2,597 ha) and Nhơn Trạch (2,535 ha). 2. Promote dialog said "KCN KCN Đại An" — duplicate prefix. Reworded to "Sắp promote: <name>" so the row name stands on its own. 3. Province was "Chưa xác định" on 2,107 of 2,193 OSM rows. The OSM tags lacked any addr:* hint, so the importer never had anything to write. Added `scripts/data/vn-province-centroids.ts` (63 provinces with capital-city coords) and a `nearestProvince(lat, lng)` fallback in `parseFeature()`. Shipped a one-shot backfill script `scripts/backfill-osm-provinces.ts` and ran it — every existing OSM row now has a province (Hồ Chí Minh: 408, Lạng Sơn: 232, Quảng Ninh: 220, Hà Nội: 172, Hải Phòng: 105, …). Admin can correct on promote if the nearest-centroid heuristic picked the wrong neighbour for a long-thin province. 4. Public map looked empty — only 20 curated parks visible. Added an opt-in toggle "Hiển thị KCN OSM" with a small legend above the map. When on, the bbox endpoint returns OSM raw rows too; markers render in amber (vs. green for curated) at slightly smaller radius and lower opacity, so the visual hierarchy stays clear. Refetch is wired through a ref so the toggle takes effect without remounting the map. Verified in browser preview: zoom-out shows clusters of 320 / 71 / etc. across the country with the toggle on, and just three small clusters (20 curated parks) when off.
