Canada Large Fires by Year (NFDB)

cwfis/large-fires-by-year

Returns the largest wildfires of one year from the National Fire Database large-fire points of the Canadian Wildland Fire Information System (fires over 200 hectares, 1970 to 2024), largest first. Each feature is a point (longitude, latitude) with properties including NFDBFIREID, SRC_AGENCY, FIRE_ID, FIRENAME, YEAR, MONTH, DAY, REP_DATE (report date), OUT_DATE, SIZE_HA (final size in hectares), CAUSE (H human, N natural, U unknown), FIRE_TYPE and RESPONSE. Returns up to `count` features (1 to 25, default 10) as a GeoJSON FeatureCollection with numberMatched; a year with no records returns an empty `features` array.
