The Crowdsourced Wind Maps project provides wind zone contour lines showing how the wind funnels into channels and around headlands, to improve marine navigation for all types of vessels. Data from internet-connected wind sensors is merged with the worldwide meteorological data forecast. There are never enough weather stations, but this project uses data from users who move around. This innovative solution archives incoming data, allowing the generation of wind maps showing how the wind is flowing even when there is no live data in a particular location.
