AbstractThe magnetic field of the Earth is influenced by the electromagnetic environment of the solar system. The disturbed interplanetary environment changes the conditions of the natural electromagnetic environment of our planet and affects normal operation of space and ground technological infrastructures, such as power grids and pipelines.Geomagnetic activity can be described by the sizes of the disturbances in the Earth magnetic field and how often they occur. Geomagnetic activity depends on the geographic location of the observing point. It is defined by the geometry of the Earths geomagnetic field and its interaction with both the charged particles produced by the Sun and the solar/interplanetary magnetic field fluctuations. Canadian territory covers three zones of geomagnetic activity: the polar cap (north of Cambridge Bay), the auroral zone (between Cambridge Bay and Meanook) and the subauroral zone (south of Meanook). The highest geomagnetic activity is observed in the auroral zone.
Summary(Plain Language Summary, not published)
The map was originally published online in the Atlas of Canada, 6th Edition as an interactive digital map derived from a shapefile and mapped online using MapServer, a platform for publishing spatial data to the web. In order to preserve the geographical content of this Edition during its publication from 1999 to 2009 all the maps have been converted from their online interactive form to a raster and made available in PDF and JPEG.
