Researchers are using remotely sensed data and satellite imagery to map glacier loss in Western Canada. Scientists use satellite images, like those produced by the long-running Landsat Earth observation satellites, to compare the size and extent of glaciers over time. By examining images from different years, they can track changes in glacier size, shape, and movement.
