| An overlay with high-res wind zones will be added to the free SailTimer chartplotter app shown above, and will be made available under free license to other apps and weather platforms.
But what happens if there is no-one sharing data in the particular location you want to view? That is the usual problem with crowdsourced data, but there is a great solution in this case… When a user shares wind data in a particular location, we archive that data and match it up with the marine weather forecast for that precise location. Then in future if you need to see a high-res wind map, we can search back to any previous data for that location with the same wind direction in the forecast. Even in a location with only one boat sharing data, that boat can cover an entire coastline and a lot of wind conditions over the course of one season.
You don't even need an internet connection out in the boat to see these high-res wind zones. GRIB and marine weather forecasts project hour by hour, so before leaving your normal wifi or internet connection you can get the most recent wind map of crowdsourced data merged with the marine weather forecast for the next hours or days. Then if the forecast is from a certain direction, you'll know what the wind will be actually doing in a certain anchorage or how it will be funneling down a certain channel.
