![]() This data is primarily from historical hydrographic surveys that were carried out by the Canadian Hydrographic Survey (CHS). ![]() However, the database that was constructed during the IBCAO project holds bathymetric data of a high quality throughout most of the Canadian Arctic Archipelago, justifying a compilation resolution that is better than 2.5 x 2.5 km. The horizontal grid cell size is 2.5 x 2.5 km on a Polar Stereographic projection, which is adequate for regional visualization and analysis, but which may not be sufficient for certain geoscientific and oceanographic applications. IBCAO is a seamless bathymetric/topographic Digital Terrain Model (DTM) that incorporates three primary data sets: all available bathymetric data at the time of compilation the US Geological Survey GTOPO30 topographic data and the World Vector Shoreline for coastline representation. McCracken, M.Ĭurrently, the International Bathymetric Chart of the Arctic Ocean (IBCAO), contains the most up-to-date digital bathymetric model of the entire Canadian Arctic Archipelago. This model should prove to be a valuable tool for enhanced visualization and analyses of the floor of Mono Lake.Īn Integrated Bathymetric and Topographic Digital Terrain Model of the Canadian Arctic ArchipelagoĪlm, G. The model was created using a geographic information system (GIS) to incorporate these data with new observations and measurements made in the field. With the permission of Pelagos Corporation and DWP, these data are used to produce a digital model of the floor of Mono Lake. No digital models, including shaded-relief and perspective-view renderings, were made from the data collected during the survey. From these maps, the DWP hoped to predict consequences of the drop in lake level that resulted from their diversion of streams in the Mono Basin. The result of that survey was a series of maps at various scales and contour intervals. In 19, Pelagos Corporation of San Diego (now Racal Pelagos) undertook a bathymetric survey of Mono Lake in eastern California for the Los Angeles Department of Water and Power (DWP).
