Description

This data set illustrates the geoscience information of the Ottawa/Outaouais (Ontario/Québec) area including geological history, subsurface database, stratigraphy, bedrock, surficial and hydrogeology maps and reports.

The geoscience information is compiled digitally in the form of points, polylines and polygons. This information constitutes the geoscience database which is processed by Geographic Information Systems (GIS) in order to integrate different sources of information and produce derived documents.

Point data comes from engineering borehole logs, water-well records and seismic records. Linear and polygonal geoscience information are taken from surficial and bedrock geology maps. The database also contains hydrographic and topographic information.

The point database released on computer diskettes contains information on the area studied until 1977 and compiled by the Geological Survey of Canada (GSC). This database was updated by including Ontario and Québec water-well records and engineering reports compiled up to 1995. Since the water-well records belong to the provinces, these cannot be released by the GSC. The new information is also used to produce derived documents and maps.
