Box 4400 Fredericton, N.B. Canada E3B 5A3 Price: $10.00 Preface and Acknowledgements In February, 1985, Mr Bernhard Kauter, a licensed surveyor practicing in the Nidau district in the canton of Bern was the featured speaker at a series of presentations of a one-day seminar entitled "Land Information and the Land Surveyor". The seminar, sponsored jointly by the L.I. committee of C.I.S. and by C.I.S. branches, was presented at Fredericton on Feb. 12, at Toronto on Feb 14, at Calgary on Feb. 17, at Edmonton on Feb. 19, at Victoria on Feb. 21. At each seminar, Bernhard described the Swiss cadastre and his role as the District Surveyor in the maintaining of it. At most of the presentations there was time for only a few questions before the lunch break. In the afternoon, after a panel, or a speaker, addressed some aspect of land information of particular interest to the Branch, there was general discussion. Bernhard's text, edited and complemented with partial copies of the many maps he displayed, is presented in Part I. In Part II, the input from the panelists, along with an edited transcript of the discussion at each branch, is presented. Although the same or similar questions about Bernhard's presentation were asked on different occasions, no attempt has been made to avoid redundancy. The discussions were intentionally informal, consequently not all of those who asked questions or made comments were recorded and in some instances the taped record was inaudible. To all who remain anonymous or whose words were lost to posterity, my apologies. To Ed Kennedy, then President of C.I.S., for pressing me to do something with the L.I. committee; to Branch officers and committees for their whole-hearted cooperation and especially to: Rejean Castonguay and Doug Morgan, Fredericton Branch; Dave Lever, Toronto Branch and Lorraine Petzold, Association of Ontario Land Surveyors; Stephen Nichol, Calgary Branch; Ric Beaumont and Ted Smith, Edmonton Branch; Gary Sawayama, Victoria Branch to my graduate students, Dave Coleman, Sylvie Laroche, Walter Mayr, David Pullar, Matthias Uhlenbruck, Michal Lodin and Albert Yeung for their assistance in preparing the transcripts; to Prof. Alphonse Miserez of Lauzon University for liaison with the Swiss Association of Surveyors to the Swiss Association of Surveyors for answering my request for someone in private practice to explain the Swiss system to us in Canada; to Monique Kauter for her patience and good humour in listening to Bernhard and I talk shop as we travelled between seminars and, finally; to Bernhard Kauter for preparing a very clear description of both the Swiss cadastre and the role of the District Surveyor in maintaining it, for bringing a display of some 25 maps to Canada and for taking two weeks away from his practice to present these seminars, my sincere thanks.
