Abstract: This dataset contain the 1:20,000 scale contour elevation text converted from the Provincial Digital Base Mapping Project. These contours require the use of elevation text to properly interpret the elevation value of a specific contour. There are two major types of contours, index contours and intermediate contours. Index contours are identified every 5th contour line. For Alberta, the index contour intervals occur every 50 metres in relatively flat terrain and every 100 metres in mountainous terrain. Intermediate contours are contour lines that occur between the index contours. For Alberta, the intermediate contour intervals are every 10 metres in relatively flat terrain and every 20 metres in mountainous terrain. Where elevation change is sudden, intermediate contours may be deleted and only index contours are shown. The elevation text is associated with the index contours. Currently, no contour information exists for Banff, Jasper and Wood Buffalo National Parks and also for the extreme north east portion of the province. See the Completeness Report in this metadata record for details regarding coverage.

Abstract:
This dataset contain the 1:20,000 scale contour elevation text converted from the Provincial Digital Base
Mapping Project. These contours require the use of elevation text to properly interpret the elevation value
of a specific contour. There are two major types of contours, index contours and intermediate contours.
Index contours are identified every 5th contour line. For Alberta, the index contour intervals occur every
50 metres in relatively flat terrain and every 100 metres in mountainous terrain. Intermediate contours are
contour lines that occur between the index contours. For Alberta, the intermediate contour intervals are
every 10 metres in relatively flat terrain and every 20 metres in mountainous terrain. Where elevation
change is sudden, intermediate contours may be deleted and only index contours are shown. The elevation text
is associated with the index contours. Currently, no contour information exists for Banff, Jasper and Wood
Buffalo National Parks and also for the extreme north east portion of the province. See the Completeness
Report in this metadata record for details regarding coverage.
Purpose:
The Contour dataset provides users with representation of elevations on the landscape for a majority of the
province. See the Completeness Report in this metadata record for details regarding coverage. A contour is a
line that provides the user with a measure of elevation above mean sea level. Each contour line represents
the same elevation value along its entire length. The contour annotation is the text that defines the
elevation of the contour line.

Contour arcs are a cartographic product and they do not have any elevation values attributed to the
spatial features. These contours require the use of elevation text to properly interpret the
elevation value of a specific contour. Index contours are identified every 5th contour line. For
Alberta, the index contour intervals occur every 50 metres in relatively flat terrain and every 100
metres in mountainous terrain. Currently, no contour information exists for Banff, Jasper and Wood
Buffalo National Parks and also for the Extreme north east portion of the province.
