paper it will be impossible for me to lay before Mr.
Butler such plans of the Province as will exhibit the
vacant crown lands with any degree of accuracy and
this deficiency of information will be the more apparent
as Upper Canada has been carefully surveyed and very
excellent compilations made therefrom".
Ten years later, in 1848 little progress had been made and
Baillie was quite desperate about the system. In a letter to Privy
Council he had this to say
"...the present system, if system it can be called, of
surveying isolated lots of land by separate and often ill
connected surveys, has presented to my mind only a
complete mass of confusion, but having repeatedly
represented the evil effects which must at some future
period inevitably ensure, I felt that I had done my
duty".
2.1 The "20 Chain" Map Series
It was nearly one hundred years later (1944) in the Brief on
"Forestry and Post-war Reconstitution in New Brunswick"
(Burchill 1944) that the need for a province-wide map series
was recommended and acted upon. It had this to say:
"WHAT MUST BE DONE
To take advantage of the "opportunity" and remedy the
faults of the "present situation," action is necessary by
both government and industry. The plan of action
which we recommend includes certain projects which
should be carried out as soon as men and equipment
are available.
Among these are:
1. Aerial photographs and maps of the whole
province..."
Soon after the report was published, the project to map the
whole territory was begun, and 10 years later, for the first time
in history, the province had a series of maps at the scale of
1 inch = 20 chains.
2.2 The Orthophoto Series
Toward the end of the 1960's, the series of post-war maps
could no longer meet the New Brunswick needs. It had to be
revised. Even though the best technology of the day had been
used, its accuracy no longer corresponded with current needs.
This was partly because of the imprecise control survey network
and the rather unsophisticated methods of mechanical
adjustment and compilation of topographic features.
From 1960 to 1963, the primary control survey network was
densified (Hamilton 1974), and from 1969 to 1972, a secondary
control survey network was established. Aerotriangulation,
adjustment, and photogrammetric methods had developed
considerably. A decision was made, therefore, to produce a
new base map series instead of revising the series of post-war
maps.
After reflecting on the matter for several years, in 1971, the
decision was made to go ahead with an orthophotographic base
map at the scale of 1:10 000. Three versions were produced:
1) the planimetric maps, to which were added certain themes
such as hydrography through the use of photogrammetry,
symbols representing monuments, etc.;
2) the hypsographic maps with 5 metre contour lines; and
3) the property maps.
It should not be surprising that the orthophoto was chosen as the
basic map. One need simply to remember that, toward the end
of the 1960's, Canadian social democracy had reached its peak,
It was probably the first time in Canada that insistence was so
firm on the importance of acquiring a tool, being the
orthophoto, that the public could understand, a tool that would
enable us to communicate with it, as well as encourage the
public to participate in and contribute to the decision-making
process. It was the backdrop against which the link between the
public and spatial information was established. Implementation
of the orthophoto meant more than recognizing the public's
right to spatial information; it meant giving it the tools of access
to information, offering it directly products that everyone could
comprehend. The orthophoto's success was extraordinary
(Castonguay 1984).
Although the public was enchanted by the orthophoto, in the
1980's in most cases Canadian administrators of geomatics
programs shrank back from the social viewpoint and encouraged
a return to standard map making.
During the 1970's and early 1980's, the digital representation
became more and more popular. Digital topographical
conventional maps were sold with the promise that revision
would be economical and that it would help us to handle all
kinds of spatial questions. The orthophoto, even though
digitally produced, did not lend itself well to revision. The
decision was therefore to produce a new base map series.
2.3 The Digital Topographic Base Series
In 1983, New Brunswick embarked on a program to create a
digital topographic base according to a standard equivalent to
the production of maps at the scale of 1:10 000. The data base
is to be completed in 1994. But now, in some regions (Figure
2-1), this data base is already 10 years old. Unless the data is
updated, the investment of over $10 million will lose more and
more of its value.
