Re: Sundials and Google Maps

[Phil Walker]

Hi Brad,

Here is a photo of one of my dials I bought from Helios, Wiesbaden, Germany,  
an (almost) universal equatorial dial incorporating a map projection on the 
dialplate.

Here is the page in my website: 
http://www.sundial.pwp.blueyonder.co.uk/JACKTILE.HTM. The photo is at the 
bottom of  the page.

Cheers,
Phil Walker

  I've incorporated Google Maps into an Oughtred dial. As you know, the 
Oughtred dial can be drawn on any azimuthal map projection (Oughtred himself 
chose the Stereographic). Since the dial is drawn on a map, it's possible to 
drawn Earth features such as countries as part of the dial. What I've done (and 
I'm pretty sure this is new) is incorporate the ability to download and use 
Google Maps in the dial. The technique works with geographic dials as well.
  I tried to send an example to the SML but the image is 90KB+ so will not pass 
the size filter. I'd be happy to send the diagram to whomever is interested.
  Brad
