There are two generic types of highway shields: Trans-Canada Highways and Province Highways. Each type has three layers, each of them optimized for a specific zoom level display.
These layers contain fixed-point shields. When one of the layers is added to a map window, the shields display on top of the appropriate Highways layers. The text specifying each route number is drawn from an autolabel on the associated Shields layer.
Each type of shield is contained in separate tables, organized by Census Division (in
Census Division-tiled packs) or by province (in province-tiled maps).
Note: To support
the independent use of Highway Shields, a lookup table—
StreetProCanHighwayShieldRefer.tab—has been included in StreetPro Canada
2010.03 and above. It lists, for each shield code, a description of the highway type
and the associated MapInfo Pro symbol definition.
