Septima Skyggekort is an interactive map which visualizes the shadows cast past times Denmark's buildings at whatever lx minutes of the 24-hour interval in addition to for whatever 24-hour interval of the year.
The map was created using the OpenLayers mapping library using peak information from Styrelsen for DataForsyning og Effektivisering, earth information agency of the Danish government. The peak information appears to come upwards from a Lidar survey of the whole of Denmark. This agency that you lot tin strength out role the map to persuasion the length in addition to positions of shadows for whatever edifice in addition to for whatever tree inwards the whole country. Just role the ii slider controls on the map to conduct the 24-hour interval of the twelvemonth in addition to the fourth dimension of the 24-hour interval you lot wishing to come across visualized on the map.
Norway's The Shadow Visualization Demo is roughly other impressive demonstration which shows dynamic shadows on an interactive map. This map uses digital terrain model information in addition to edifice peak information from OpenStreetMap. Because the map knows the peak of the terrain this map non exclusively shows the shadows of buildings simply the shadows cast past times hills in addition to mountains equally well.
Again you lot tin strength out role the slide controls to conduct whatever fourth dimension of 24-hour interval in addition to whatever 24-hour interval of the year.
In New York you lot tin strength out role the New York Times' Mapping the Shadows of New York City interactive map to visualize the shadows cast past times the city's famous heaven scrapers (and all of its other buildings equally well.)

They too claim that the total of fourth dimension a place spends inwards shadow during daylight hours tin strength out touching on everything from storey rental prices to the menstruum of human foot traffic on the city's streets.
The map uses edifice peak information provided past times the city. With the tending of the Tandon School of Engineering at New York University the NYT used this peak information to calculate the full release of minutes that a given betoken spends inwards shadow over the course of report of a day.
If you lot are interested inwards creating your ain shadow map hence you lot mightiness last interested inwards SunCalc.js, a javascript library for calculating the put of the sun.
