Download OGS Earth (357MB)

OGS Earth is a set of data that can be viewed using Google Earth.  This dataset contains provincial scale image overlays including geophysics (magnetics), bedrock geology and surficial geology.  A shaded relief map created using NASA's Shuttle Radar Topography Mission data is provided as a base layer.  However, the shaded relief map has been resampled to reduce the file size.  An index map for mining assessment files is also included in this dataset, which provides links to locations at the GeologyOntario website where the actual assessment files can be downloaded.

Download OGS Earth 2 (565MB)

OGS Earth 2 is a set of data that can be viewed using Google Earth.  This dataset contains a set of data products useful for Land and Water Stewardship initiatives including surficial geology, bedrock topography and physiography. The resolution of image data in this dataset is generally better than that included on the original OGS Earth, however, this dataset only covers Southern Ontario (south of latitude 46 north). An index map for OGS publications is also included in this dataset, which provides links to locations at the GeologyOntario website where the actual publications can be downloaded.
