Field notes
The page describes two modes: visitors can choose numbered candidate spots at parks or riverbanks and inspect a night-scene 3D view in advance, then use a camera overlay at the venue to check the expected burst area against buildings or trees. It says the visibility calculations use building heights and terrain from sources including Japan’s MLIT PLATEAU 3D city models. One Sumida River example lists a 2.54 km distance, 207° bearing, 4.2° elevation for a 5号 firework, and a 7.5-second sound delay.
