I have a vertical pole in an open area of my back yard. Is it
possible to layout a sundial with its shadow? Is there a program to
do this or would it have to be done
by marking points over a years time? Also what would the lines look
like--the classic analemma or something else?
Thanks for the help,
Vince
Hello Vince,
You don't mention the size (height and diameter) of the pole. If you
can use the tip of the pole, or conveniently place an indicator
(nodus), you can easily construct a "normal" horizontal dial, or
perhaps an "hours until sunset" dial. Either of these dials only need
straight lines, and can be designed using readily available software.
Check the NASS website under Links.
Good luck with your project.
