Новый ekb_geoportal_client.py — WFS-клиент муниципального геопортала ЕКБ (Geometa GeoServer, public). features_at_point (CQL INTERSECTS), features_in_bbox (CQL BBOX), zone_index_at (crosswalk координата→индекс ПЗЗ). EPSG:4326, OGC WFS GetFeature (не WMS — reproject-баг). Единый источник землепользование/КРТ/ППТ/ЗОУИТ для ЕКБ. 7 тестов. Foundation #1067 C7; wiring в C8/D9. Refs #1067. Co-authored-by: lekss361 <lekss361@gendsgn.local> Co-committed-by: lekss361 <lekss361@gendsgn.local>

"""ЕКБ муниципальный геопортал (ИСОГД / Geometa) — WFS-клиент (#1067 C7).
|
||||
|
||||
Геопортал Екатеринбурга (`геопортал.екатеринбург.рф`) — открытый GeoServer на ~1149 слоёв,
|
||||
без авторизации, нормальный TLS. Единый источник «что построят / землепользование» для ЕКБ:
|
||||
ПЗЗ-регламент, функц.зоны генплана, КРТ, ППТ/ПМТ, ЗОУИТ — то, чего НСПД (только геометрия +
|
||||
reg-номер) и городские документы по-отдельности не дают структурно.
|
||||
|
||||
Primary интерфейс — **стандартный OGC WFS GetFeature** (`/api/gis/ows/3/portal/wfs`):
|
||||
OGC-стандарт стабильнее reverse-engineered `urbanCard`-API и покрывает все слои одним вызовом.
|
||||
|
||||
⚠️ WMS GetFeatureInfo на этом GeoServer багует на reproject («too close to a pole») —
|
||||
использовать ТОЛЬКО WFS GetFeature.
|
||||
|
||||
CRS: WFS отдаёт `geoloc` (геометрия) в EPSG:4326 (lon/lat). В CQL `POINT(lon lat)` порядок
|
||||
X=lon, Y=lat. `geoloc_orig` (МСК-66) НЕ запрашиваем.
|
||||
|
||||
Источник разведки (live-verified 2026-06-06): vault
|
||||
research/EKB_Geoportal_WFS_Construction_Intel_Jun06.
|
||||
Рич ПЗЗ-карточка (3 списка ВРИ + предельные параметры) — отдельным дополнением через urbanCard
|
||||
(см. research/EKB_Geoportal_PZZ_Content_API_Jun06), здесь НЕ реализуется (follow-up).
