> Is There Shade? answers one question precisely: will a specific seat at a
> specific venue be in the sun or the shade at a specific date and time. We
> compute the sun's real astronomical position and run it against verified
> venue geometry (compass orientation, seating tiers, roofs and canopies),
> fused with live event schedules (MLB, TixBit) and hour-by-hour
> weather. Coverage: all 30 MLB ballparks, all 30 NFL stadiums, major college
> football and soccer stadiums, and 200+ outdoor amphitheaters. We also cast
> real building shadows over satellite imagery for any point in the US
> ("Anywhere" mode), including 115 major landmarks.

## Method
Astronomical sun position (no estimates), venue orientations verified against
satellite imagery, USGS 3DEP lidar, and MLB Stats API azimuth data, roof and
tree geometry from USGS 3DEP aerial lidar with Overture/OSM fallback, weather
from NWS/Open-Meteo. Shade fractions are modeled per section per 15-minute
step across an event. The shadow model is audited against real satellite
imagery. Full write-up: https://isthereshade.com/methodology/
