A CANADIAN GRID SYSTEM IN 3 DEGREES TRANSVERSE MERCATOR ZONES

Abstract

All geodetic networks that rest previously fixed control are best computed in plane coordinates. Under this category fall a great deal of firstorder triangulation and, of course, the whole volume of lower-order work- all the way down to the last monuments from which detail surveys originate. A geodetic grid must be designed to meet first-order accuracy and should be established on federal rather than provinical level. Its use requires precomputed tables based on some conformal map projection, preferably the Transverse Mercator (Gauss-Kruger) projection. Congruent projection zones, simple scale factor, free choice of central meridian for local plane coordinates in cities and metropolitan areasall these features of the Transverse Mercator find no parallel in any other map projection. Following a brief introduction to the subject, a set of tables for a proposed Canadian grid system is presented.
