Lights at Sea is an interactive map which shows the place of lighthouses approximately the world. The map uses unlike colored flashing markers to demonstrate the lite characteristics of each lighthouse shown on the map.
Individual lighthouses tin accept unique lite characteristics as well as then that mariners are able to position them as well as purpose them equally an aide to navigation. These lite characteristics are created yesteryear using unlike colored lights, frequencies as well as lite patterns. On OpenStreetMap these lite characteristics are recorded using the tags 'seamark:light:sequence' as well as 'seamark:light:colour'. Lights at Sea uses these tags to demonstrate the color of lights as well as the lite sequences used yesteryear the private lighthouses.
The arrive at of lite emitted yesteryear a lighthouse is measured yesteryear how many nautical miles away it tin survive seen. In OSM the arrive at of a lighthouse tin survive assigned using the tag 'seamark:light:range'. I assume that the size of the lighthouse round out markers on the Light at Sea map is beingness used to dot each lighthouse's range.
One matter that is real hitting on the map is the huge release of lighthouses inwards Europe compared to the United States. Kingdom of Norway inwards item seems to accept an inordinate release of lighthouses. According to Wikipedia in that place are genuinely less than 155 operational lighthouses inwards Norway. OpenStreetMap, however, seems to accept plotted many to a greater extent than lighthouses than that on the Norwegian coastline. This is presumably the travel of Slartibartfast.
One matter non shown on the private map is the 'daymark' patterns used on private lighthouses. Just equally lighthouses tin accept private lite characteristics to aide maritime navigation they tin likewise accept unique 'daymarks' which enable mariners to position private lighthouses during the day. Daymarks oftentimes consist of large colored painted stripes, diamonds or other patterns.
