AbstractThe Geological Survey of Canada (GSC) is a federal agency that operates collaboratively with multiple provincial and territorial agencies that have direct responsibility for natural resource and groundwater management. Three dimensional geological mapping has been embraced at the GSC in the past 20 years as data collection, analysis, interpolation, visualization, and presentation modes have evolved with the advent of increased computer processing capacity, graphic user interfaces, and 2-D and 3-D geographic information systems. Nevertheless, the fundamental requirements for 3-D geological mapping have not changed radically from traditional geological investigations for groundwater studies. Basin analysis concepts provide the cornerstone of 3-D mapping at the GSC. Within this framework the emphasis is on data collections and an understanding of the basin geological history. This knowledge base provides a framework for interpretation of disparate datasets and data correlation necessary for input to interpolation algorithms for the construction of 3-D models. Basin analysis has been adapted across the groundwater program as a common methodology for 3-D studies. Subsequent data processing, interpolation and visualization within GIS software remain discretionary depending upon geographic and geological complexity, study objectives and partnership requirements.
