In conjunction with my previous post I have discovered a great free desktop application, for tracking the sun’s movememnt through the day at any location throughout the world. Thanks to a blog post on David Tejada’s site. You can now use the ‘The photographer’s Ephemeris‘ Tool to see very comprehensive information about the Sun and Moon’s position overlaid on a satellite image map. If used  with the Elevation of Obstacle Calculator you can determine the precise distance of shadow fall from an object with the sun behind.
