Valgusreostuse hinnang

GET /lightpollution

Hangi hinnanguline Bortle'i klass (1-9) mis tahes asukoha jaoks lähedalasuva rahvastiku tiheduse põhjal. See on hinnang, mitte satelliidi mõõtmine — see kasutab 100 km piires kaalutud rahvastikku taeva heleduse ligilähedaseks hindamiseks. Tagastab Bortle'i klassi, taevakvaliteedi hinnangu, hinnangulise palja silmaga nähtavate tähtede arvu, SQM (Sky Quality Meter) hinnangu ja virmaliste vaatlemise sobivuse. Täpne suurte linnade ja kõrvaliste piirkondade jaoks; vähem täpne eeslinnades. Kasulik astronoomiarakendustele, virmaliste turismile, astrofotograafia planeerimisele ja pimeda taeva teadlikkusele.
