GPS or GNSS are essential
among practitioners in land
surveying and related geospatial
engineering fields. GPS surveying
has many advantages, offering
a longer operation range and
does not require a direct line of
site. It is an alternative, often a
compliment to other methods in
land surveying. However, many
practitioners do not feel well prepared to apply GNSS
technologies, either because the concepts seem too
complicated or they might have limited exposures to the
fundamentals. GPS for Land Surveyors, 4th edition, is an
excellent reference for students, professionals or anyone
who has interest in GNSS technologies
The original geodetic surveys of Canada were computed
on the Bessel 1841 ellipsoid. In 1880, when the U.S.
Coast & Geodetic Survey chose to adopt the ellipsoid
that had been published by Colonel A. R. Clarke of the
British Royal Engineers
in 1866 for North America,
it was only logical for Canada to adopt the same
ellipsoid.
