Дополнение к bbox: ?polygon=<GeoJSON> для произвольных полигонов
(ground stations coverage, custom AOI). Один из bbox/polygon —
взаимоисключающие; передача обоих → 400.
Repository:
- findActiveByPolygonGeoJson native query через PostGIS
ST_GeomFromGeoJSON(polygon) → ST_SetSRID(_, 4326). DB-side parsing,
не нужен jts-io-common.
GeoJsonPolygon validator (app-side, structural):
- Парсит JSON, проверяет {"type":"Polygon","coordinates":[[...]]}
- RFC 7946 closed-ring check: first point == last
- >= 4 points в каждом ring (3 вертекса + closing point)
- Поддержка holes (multiple rings)
- Coordinate range validation: lon ∈ [-180,180], lat ∈ [-90,90]
- DoS guards: MAX_JSON_BYTES = 1MB, MAX_POINTS = 50_000
- Canonical re-serialize (whitespace stripped) перед DB
Tests (13 в GeoJsonPolygonTest):
- Valid square + polygon with hole
- Reject empty/null/non-JSON/non-object/wrong-type/missing-coords
- Reject too-few points / unclosed ring
- Reject lon/lat out of range
- Reject malformed point [no lat]
- Reject too-large JSON
Total project tests: 161 → 174.
API now supports:
GET /api/v1/{dict}/records?bbox=west,south,east,north
GET /api/v1/{dict}/records?polygon={"type":"Polygon",...}
Альтум-задача (rect AOI) и геопортал (polygon AOI) разблокированы
от client-side full-fetch + filter.
