Urban Geology of the National Capital Area, Canada - Basemaps Urban Geology of Canada's National Capital Area is a pilot project aiming at developing approaches, methodologies and standards that can be applied to other major urban centres of the country, while providing the geoscience knowledge required for sound regional planning and environmental protection of the National Capital Area. This data set presents 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 point, linear and polygonal data. This information constitutes the geoscience database which will be processed by Geographic Information Systems (GIS) in order to integrate different sources of information and produce derived documents. Point data come 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. All point, line and polygonal data are georeferenced so different types of information can be overlaid and analyzed with a GIS. The digital information can be reproduced by GIS as maps at various scales or can be analyzed to produce regional maps from point data. It is also possible to combine point, line, and polygonal data to produce derived or thematic maps. 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. It is possible to produce a map showing potential landslide areas by linking various parameters such as areas of sensitive clays, topography, drift thickness, drainage, and proximity of water saturated sand deposits. 1994-01-01 2017-05-04 Natural Resources Canada NRCan.geogratis-geogratis.RNCan@canada.ca Form DescriptorsNature and EnvironmentScience and Technologygeologicalgeomorphologygeophysicalhistorical geologyhydrologypaleoecologyroad mapsroad networksstratigraphywater Download ZIP (shp,xls) through HTTPZIP http://ftp.geogratis.gc.ca/pub/nrcan_rncan/archive/vector/geology/NCR_urban_geology/GEOLGEN.shp.zip
