Hi Bill,
In the field of gnonomics the Longyearbyen sun dial
<http://sun.nessy-edv.at/> is a highly relevant and admirable project.
As a match to my enquiry it is irrelevant: The continuous spider grid is
missing. However, up to now it is - as I said - the /closes/t hit.
As a match I would require the properties
- horizontal
- polar gnomon
- wide gnomon
- calculated for beyond the arctic or antarctic circle
-spider mesh

Why is the Longyearbyen sundial irrelevant to your project?

Hi all,
When studying the wide polar gnomon one inevitably encounters edge
changes to be respected. My special focus is on a horizontal dial
for a location with midnight sun. Around midnight the scale needs
two overlapping sections. I have designed a solution based on a
uniformly convoluted spider scale (see attached jpg (203 kB)).
My question: *Is a comparable dial existing anywhere?* My web
research produced only nil returns. The closest but not relevant
hit is the Longyearbyen sun dial
<http://sun.nessy-edv.at/images/extras/dialabove.jpg>.
Kind regards
