Centre for Topographic Information Sherbrooke, Natural Resources Canada

Data Center Description
The Centre for Topographic Information was created in 1988 as part of
Geomatics Canada within Natural Resources Canada's Earth Sciences
Sector. It provides the digital representation of the Canadian
landmass and, in specific terms, it establishes, updates, and
distributes data from the National Topographic Data Base (NTDB). It
also distributes other related products for fees such as the Canadian
Digital Elevation Data (CDED), Vector Map Level 0 (VMap0) data, the
Arc Digitized Raster Graphics (ADRG) product, the Administrative
Boundaries and the Updated Road Network (URN). Also, Toporama and the
CGDI Data Alignment Layer are two products that CTIS distributes for

CTIS as played a key role in the technological changes that have
transformed the Canadian topographic information community. Nearly a
hundred CTIS specialists have contributed significantly to the
conversion of maps into digital topographic data leading a revolution
in mapping that has opened new horizons in many fields of business.

In a constant effort to provide excellence in digital topographic
data, the CTIS recently reengineered its activities and is now better
equipped to continually improve and enrich topographic and toponymic
data on Canada.
