History ?[edit]
According to the article, currently:
- The first known instrument for directly producing a drawing of a site was developed by Johann Richter, also known as Johannes Praetorius[1], a Nuremberg mathematician, in 1610.[2] This circular table, called a tabula praetoriana, mensula praetoriana or Pretorian table, used a simple alidade and allowed a piece of paper to be slipped under the alidade for drawing.
However, according to this page [1], both the idea and the name go back at least 50 years earlier than this. Jheald (talk) 15:53, 30 April 2008 (UTC)
- Interesting - I had the opportunity to do further investigation at the library and found your comments to be true. I have updated the section. --Michael Daly (talk) 19:12, 6 November 2008 (UTC)
- Further to above:
- US Coast and Geodetic Survey (1869) Plane Table & its use in topographical surveying, Page 3, Van Nostrand.
- Praetorius is described as inventing the plane table in 1537, with the first published description not appearing until 1625 by Leonhard Zubler who ascribes the invention to a stone mason, Eberhart.
