NOAA Office for Coastal Management Coastal Digital Elevation Model: Lake Ontario

Description

These data were created as part of the National Oceanic and Atmospheric Administration Office for Coastal Management's efforts to create an online mapping viewer called the NOAA Lake Level Viewer. It depicts potential lake level rise and fall and its associated impacts on the nation's coastal areas. The purpose of the mapping viewer is to provide coastal managers and scientists with a preliminary look at lake level change, coastal flooding impacts, and exposed lakeshore. The viewer is a screening-level tool that uses nationally consistent data sets and analyses. Data and maps provided can be used at several scales to help gauge trends and prioritize actions for different scenarios. The NOAA Lake Level Viewer may be accessed at: https://coast.noaa.gov/llv. This metadata record describes the Lake Ontario digital elevation model (DEM), which is a part of a series of DEMs produced for the National Oceanic and Atmospheric Administration Office for Coastal Management's Lake Level Viewer described above. This DEM includes the best available lidar and US Army Corps of Engineer dredge survey data known to exist at the time of DEM creation that met project specifications. This DEM includes data for Cayuga, Jefferson, Monroe, Niagara, Orleans, Oswego, and Wayne Counties in New York. The DEM was produced from the following lidar data sets: 1. 2011 USACE NCMP Topobathy Lidar: MI/NY Great Lakes 2. 2007 USACE NCMP Topobathy Lidar: Lake Superior (Apostle Islands) and Lake Ontario (NY, WI) 3. 2001 USACE LRE Topobathy Lidar: Lake Ontario (NY) 4. 2000 Cayuga County, New York Lidar The DEM was produced from the following sonar data sets: 5. 2015 USACE Buffalo District, Irondequoit Bay Harbor, NY 6. 2015 USACE Buffalo District, Rochester Harbor, NY 7. 2014 USACE Buffalo District, Point Breeze, NY, Oak Orchard Harbor 8. 2014 USACE Buffalo District, Oswego Harbor, NY The DEM is referenced vertically to the North American Vertical Datum of 1988 (NAVD88) with vertical units of meters and horizontally to the North American Datum of 1983 (NAD83). The resolution of the DEM is approximately 3 meters.
