ABSTRACT
In 1970, New Brunswick began production of a series of orthophoto graphic maps at a scale of 1:10 000. Those series were
completed in 1983. Orthophoto maps, produced in three series (planimetric, topographic and cadastral) were very popular then and
remain so, even though the maps are becoming somewhat outdated.
In 1983, New Brunswick undertook the creation of a digital topographic data base to 1:10 000 standards. This data base, including
a digital elevation model (DEM), will be completed in 1994.
Orthoimages continue to be an attractive solution in the management of New Brunswick's land mass. There is a new enthusiasm
for the soft orthoimage, and a number of projects are under way involving collaboration between the universities, the geomatics
industry and the New Brunswick Geographic Information Corporation. This paper looks at one of the projects recently initiated.
Moreover, there is a possibility that the provincial data base revision will be done on the basis of orthoimages. Soft orthoimages
could also complement the digital topographic data base in the year 2000.
RESUME
En 1970, le Nouveau-Brunswick se langait dans la création d'une série de cartes orthophotographiques au 1:10 000. Cette série
fut completée en 1983. L'orthophoto, produite en trois séries, c'est-à-dire sous forme planimétrique, topographique et cadastrale
fut et demeure encore trés populaire méme si les cartes commencent à étre un peu dépassées.
En 1983, le Nouveau-Brunswick entreprenait la création d'une base de données topographiques numériques selon les normes du
1:10 000. Cette base de données, laquelle inclut un modèle numérique de terrain (MNT), sera achevée en 1994.
Les orthoimages demeurent une solution attrayante dans la gestion du territoire au Nouveau-Brunwick. L'orthoimage électronique
crée un nouvel engouement et plusieurs projets de collaboration entre les universités, l'industrie de la géomatique et la Corporation
d'information géographique du Nouveau-Brunswick sont en cours. Cet exposé décrit un des projets récemment entrepris. Notons
que la révision de la base de données pronvinciale pourrait possiblement étre effectuée à partir d'orthoimages. Ces dernières
pourraient aussi étre un complément à la base de données topographiques numériques.

Brunswick have been mapped and remapped, and for each
series of maps, new technologies were used. Today, urban
maps are mostly hard copy and they are aging rapidly. As well
we are approaching the completion of the third resource series.
We are asking questions about what our infostructure needs and In New Brunswick the need for an infostructure for the

about the economical way of meeting these needs. On the one
hand, we have invested over $10 million in a soft 1:10 000
infostructure we would like to preserve; and on the other, we
are facing the demand from the new "generation": the video
generation and the image management generation. The soft
colour orthoimagery (SCO) represents perhaps an economically
Justifiable product because it can be used to protect the last
decade's investment, and in fact, provide management tools for
the future.

the establishment of the colony. However, it is under Thomas
Baillie (1824-1851) the Surveyor-General of New Brunswick,
that it was most stressed. This is illustrated when in 1838, the
lieutenant governor, John Harvey, requested Baillie to show
maps of the province to Charles Butler, a member of Lord
Durham's commission charged with increasing the general
prosperity and wealth of the colonies. Baillies reply was
