Use the Planif-Neige SOAP API at the InfoneigeWebService WSDL endpoint with GetPlanificationsForDate. Filter results by NomArr (borough name) and Etat values "2" or "3" for active operations, using zeep in Python or the soap package in Node.js.

Download the info-collectes GeoJSON for your collection type and perform a point-in-polygon lookup with your coordinates in [longitude, latitude] order. Extract the day from the MESSAGE_FR or MESSAGE_EN property using explicit day-name regex matching.

CKAN forbids CAST() on large datasets, returning a 403 authorization error. Use text comparison on coordinate fields for bounding box filters instead, remembering to swap min/max bounds for negative longitudes since text sort order is reversed.

No, snow removal data is only meaningful from October through April. Summer queries return stale or empty results, so you should guard API calls with a month check before requesting planifications.

Look up your borough's specific tax resource ID from the mapping table, then query with the civic number in AD_EMPLAC_CIV1 and a LIKE match on AD_EMPLAC_RUE. Filter CODE_DESCR_LONGUE to 'B00' for residential properties and compare VAL_IMPOSABLE across years.

All DataStore values are returned as text requiring explicit parsing, field names are case-sensitive and vary by dataset, some resources return HTTP 409, and collection GeoJSON files are download-only with no DataStore access. Borough names in filters must match exactly.
