Hva dette ikke sier

Gjengitt ordrett fra seksjonens warnings-felt, slik API-et returnerer det. Vi oversetter dem ikke: en oversettelse ville vist noe annet enn det svaret ditt faktisk inneholder.

An estimate, not an air-quality or noise measurement: vessel-hours count distinct (ship, clock hour) pairs of AIS positions in 250 m cells whose centre lies within 500 m or 1 km of the address over the last 365 days, by AIS ship type (passenger 60-69, cargo 70-79, tanker 80-89, fishing 30, tug and service 31-32 and 50-59, other). AIS coverage depends on what has been collected from Kystdatahuset; small craft without AIS are not counted.
berth_nox_index_kg is indicative, from stated assumptions because the ship register has no engine power: hours at berth of ships of at least 5 000 GT at the nearest port within 2 km x auxiliary power (0.10 kW per GT for passenger and cruise ships, 0.02 kW per GT for others) x 10 g NOx per kWh (order of magnitude for IMO Tier II auxiliary engines; IMO Fourth GHG Study 2020, EMEP/EEA Guidebook 2023). Shore power is not known and not deducted. cruise_calls_365d counts calls by passenger ships of at least 10 000 GT or a ship type naming cruise.
Only addresses within 1 km of recorded AIS traffic have a record; no record means no vessel traffic was recorded within 1 km, which inland is the expected answer. validation compares AIS vessel-hours around each port with Kystverket's port-call register and is null until both are populated.
Straight-line EPSG:25833 distances from the address point to the feature; not travel distance. Source features are imported as published, with their own accuracy and update cadence; updated_at is our import time.

Hvorfor den ikke kan prøves her

Seksjonen er ikke en del av den offentlige demoprojeksjonen. Det er en lisens- og personvernavgjørelse, ikke et tegn på at dataene mangler: de serveres til kunder med tilgang til seksjonen.
