Status of surficial geology mapping in the North / D.E. Kerr, A. Plouffe, J.E. Campbell, and I. McMartin. : M183-7/1-2022E-PDF

"The GEM program has facilitated the availability of new and converted surficial geology maps and associated digital datasets for large sectors of northern Canada, leading to about 70% of the north being mapped and digitally available. Development of the Surficial Data Model (SDM) and Canadian Geoscience Map (CGM) series have streamlined the publication process and created a common standard digital map format and geodatabase. Based on traditional and more recent remote predictive mapping methodologies, there are now three types of surficial geology CGM maps produced: Surficial Geology, Reconnaissance Surficial Geology, and Predictive Surficial Geology. The considerable number of new surficial geology maps published during GEM-1 and GEM-2, as well as upcoming map publications, has resulted in an increase of 12% map coverage north of 60˚, constituting a significant and lasting legacy of the GEM Program"--Abstract, page 1.
