Abstract

Transmission Lines - Planning to Construction: a GIS Approach
Track: Electric Utilities
Authors: Archana Srivastava

This paper describes how GIS played an integral role for the siting and regulatory application of a transmission line project in Alberta, Canada. Transmission line siting included consideration of agricultural, residential, environmental data layers as well as existing transmission facilities and costs. Satellite imagery and GPS were used for data capture and field surveys. LiDAR derived raster data helped in the display and analysis work that was used for the selection of final routes. The regulatory application included the collection, reporting and cartographic representation of information from various sources. Datasets representing the extent, physiography, relief, drainage basins, geology, soils, natural environment were used to help describe the natural and human environments that would be affected by the construction of the transmission line.
