Lake Ontario Topo Bathymetric Digital Elevation Model

Data Format(s): Lake Ontario Topo Bathymetric DEM

Coordinate system: Grid CS = Universal Transverse Mercator; Map Proj = Transverse Mercator; Horiz. Datum = NAD83; Vert. Datum = CGD28 - CDN

Abstract:
This seamless topo-bathymetric DEM is designed to represent true ground and bathymetric elevation across two sections of the GTA along the western shoreline of Lake Ontario ((i) Hamilton in the west to Niagara-on-the-Lake in the east, and (ii) Scarborough in the west to Port Hope in the east). The Lake Ontario Topo-Bathymetric DEM was constructed from two source datasets: the 2002 GTA Ortho vector data (MNRF) and 2001 SHOALS bathymetric LiDAR (USACE JALBTCX). This product is suitable for applications such as: querying elevation values in a given area and as a reference or input dataset.
