Description:

Abstract:

The Surficial Geology of Southern Ontario data set is a GIS based geological map that shows the distribution and characteristics of surficial units across Southern Ontario. It illustrates surficial deposit types, material types, geological features (e.g. drumlins, eskers) and general bedrock types and outcrops.

Purpose:

To provide a detailed overview of the surficial geology of southern Ontario and associated attributes available to the land-use planning, consulting, aggregate/industrial mineral industry and development community as well as government geoscientists, resource scientists, conservation authorities, land-use planners and academic researchers.

The geological compilation was digitized from paper maps using AutoCAD. The digital CAD files were then imported into ArcInfo v7 (UNIX Solaris OS) to create the polygon topology. These files were subsequently saved as ArcView 3.1 shape files. (Windows 95 and Windows NT OS).

Overview_Description:

Entity_and_Attribute_Overview:

The surficial geology of southern Ontario consists largely of varying types and thicknesses of deposits emplaced primarily during the Quaternary period. These surficial deposits overly a bedrock terrain consisting mainly of Phanerozoic sedimentary rocks that overlie older Precambrian rocks of the Canadian Shield. The data used in generating the map was derived from Quaternary maps, primarily at a scale of 1:50 000, completed by the OGS and Geological Survey of Canada (GSC) for most of southern Ontario over the past 40 years. A total of 124 maps, 36 of which belong to the GSC, were used to create the seamless coverage. These original, tiled maps existed as either digital vector or raster format. The raster images were rubber sheeted to a geographic base and digitized (head's up) according to standards established for the project. Polygonal, point and line information was captured as part of the automation process. Coverages created include; sgu_poly, sgu_point, sgu_line, sgu_mor, sgu_misc, ogs_pits and sgu_anno. Attribute tables were built and populated with various geological related information. The original maps contained legends of varying detail and terminology, therefore, a single, standard legend suitable for a 1:50 000 compilation was constructed. This legend, created using Microsoft ®Access Database software, was used to translate all original map units to the new standard legend. Each of the map attribute tables was joined to the translation table using a unique key. A series of additional attributes, for instance, primary material and genesis were extracted from each map sheet and included in this table. By capturing these attributes a variety of derivative maps can be produced. For instance, for aggregate resource assessment studies a map of gravel resources can be derived from the primary material attribute.
