버스·기차·자동차에서 어느 쪽 창가에 햇빛이 들지 궁금한가요? 선택의창은 출발 시각과 이동 경로를 바탕으로 태양 위치와 햇빛 노출을 계산해 좌석 방향 선택을 돕습니다. ■ 출발 전에 햇빛 방향 비교 출발지와 도착지를 입력하고 자동차·대중교통 경로를 확인하세요. 경로의 진행 방향과 시간에 따른 왼쪽·오른쪽 햇빛 노출을 비교할 수 있습니다. ■ 출퇴근과 장거리 여행에 매일 타는 버스, 기차 여행, 가족과 함께하는 자동차 이동 전에 참고하세요. ■ 계산 결과의 범위 태양 고도와 방위각을 기기에서 계산합니다. 날씨, 건물 그늘, 창문 차광과 차량 안의 실제 조건은 반영하지 않습니다. 결과는 참고용이며 특정 좌석이 항상 그늘이라고 보장하지 않습니다. 로그인 없이 바로 사용할 수 있습니다. 위치는 출발지 지정에만 쓰이고 백그라운드에서 추적하지 않습니다.
Shade Compass

See where the shade is falling right now, on a map. Shade Compass draws the shadows cast by nearby buildings, and the clock dial lets you spin through any hour between sunrise and sunset to see how those shadows move. FEATURES Building shadow layer on the map Shadows cast by the buildings around you are drawn over the map, so you can see which side of the street is shaded and which way around is the cooler walk. A clock dial for any hour Turn the dial to change the time and the shadows move with it. Check now whether the spot you are meeting at will be shaded at three in the afternoon. The dial covers today's sunrise through sunset. Sun and shade direction The sun's azimuth and altitude for your current location, along with the direction the shade falls. Computed on your device The sun's position is worked out on the device, with no server involved. Your location is used only for that calculation and is never sent off the device. No account or sign-up is needed. GOOD FOR Taking the cooler side of the street on a hot afternoon Choosing when and where to walk with kids or pets Picking a spot to meet outdoors Planning a route that keeps you out of direct sun PLEASE NOTE Shadows are estimated from OpenStreetMap building data and the position of the sun. Where building height data is missing or inaccurate the result can differ from what you see outside, and things that are not on the map, such as trees and awnings, are not accounted for. Treat it as a guide. Map data (c) OpenStreetMap contributors A banner ad is shown at the bottom of the screen. There are no in-app purchases or subscriptions.
