Hello Fer, It's very nice to tou, giving me such a speedy response ! The latitude is 47°29'16" N and the longitude is 7°14'37"E. It is located in south Alsace, not so far from you. My problem with you attached file is that it couln't be opened by my Navigator. What kind of *.gif is it ?
If possible you can send me you image in *.jpg Many thanks ! alain MORY fer j. de vries a écrit: > > Hello Alain, > > At what latitude and longitude the tower is? > In this picture you see the pattern for an east facing vertical dial at > latitude 52 degrees for local sun time, on a vertical cylinder. > The diameter is 435 cm, the gnomon is 25 cm. > What is about the dimension of the height and width of the dial? > What must be shown on the dial? > The software is present to draw all kind of lines for such a dial, however I > didn't test the program in all details. > It runs just like my zonwvlak program. > > Best, Fer. > > Fer J. de Vries > [EMAIL PROTECTED] > http://www.iae.nl/users/ferdv/ > Eindhoven, Netherlands > lat. 51:30 N long. 5:30 E > > ----- Original Message ----- > From: Alain MORY <[EMAIL PROTECTED]> > To: <sundial@rrz.uni-koeln.de> > Sent: Wednesday, April 26, 2000 10:02 PM > Subject: sundial on a tower > > > Good morning sundiallists ! > > > > Here I am again, with my ugly problem !
