Abstract:
The Base Features Access Powerline spatial layer is the authoritative source of powerline data for the
province of Alberta. It is a part of the Access data collection which also includes railways, roads,
cutlines and trails, and industrial facilities.
Purpose:
This layer provides a representation of the high-voltage power line (greater than 69 kV) corridors in the
province of Alberta.

Measure description:
Lineal features representing powerline arcs are continuous throughout their length and attribute
classification. Lineal powerline arcs which cross or intersect other powerline arcs within the same
coverage are precisely joined at that point, forming a node at the junction. Nodes do not exist at the
junctions of features in other coverages. Topology rules have been applied and validated to exclude
errors such as duplicates, overshoots, undershoots, and overlaps in any of these features.

Measure description:
It is acknowledged that the positional accuracy of the data is dependent on the inherent accuracy and
resolution of the imagery used, sufficient care and control of procedures used for feature
interpretation and digitizing have been used to attain the "Positional Accuracy" identified below. All
features visible in the imagery and listed in the specifications have been digitized, classified, and
integrated.

Statement:
Initially captured on paper maps as part of the Base Features 1:20,000 program in the early 1980s, this
data has been digitized and first became accessible as a digital product starting in 1998.
Specifications for capture of features outlined below.
Electrical Transmission Line:
- Through on screen digitizing, points are captured which follow the centre line of the transmission
corridor.
Updates performed by contract work are returned to Alberta Environment and Protected Areas staff for
review and audit. Approved data is loaded into repository.
