These integrated bathymetric-topographic DEMs are used to support tsunami forecasting and modeling efforts at the NOAA Center for Tsunami Research.

MetadataStandardName: FGDC Content Standards for Digital Geospatial. NCEI builds and distributes high-resolution digital elevation models (DEMs) of select U.S. They can be used for modeling of coastal processes (tsunami inundation, storm surge, sea-level rise, contaminant dispersal, etc.), ecosystems management and habitat research, coastal and marine spatial planning, and community hazard mitigation and preparedness.
NCEI builds and distributes high-resolution, coastal digital elevation models (DEMs) that integrate ocean bathymetry and land topography. Previously available here: Digital Elevation Model of Ireland, from NASAs Shuttle Radar Topography Mission (SRTM), sampled at 3 arc second intervals in latitude & longitude (about every 90m) in heightmap (.HGT) format.Latitudes & longitudes are referenced to WGS84, heights are in meters referenced to the WGS84/EGM96 geoid. This data is published by the USGS and covers a 7.5-minute area with 10-meter and 30-meter resolution. Digital surface model (first reflective surface) Orthometric height Digital terrain model (bare earth) Ellipsoid height Bathymetric surface Point cloud Other Mixed surface Model Types (1. The information is derived from elevation measurements at regularly spaced intervals.
HistoricĮTOPO5 global relief grids are deprecated but still available. USGS : A Digital Elevation Model (DEM) is a digital representation of the contours of the Earths surface. It was built from numerous global and regional data sets, and is available in "Ice Surface" (top of Antarctic and Greenland ice sheets) and "Bedrock" (base of the ice sheets) versions. NCEI's ETOPO1 is a 1 arc-minute global relief model of Earth's surface that integrates land topography and ocean bathymetry. Check the Gallery of GLOBE Images for some great map-like graphic arts from GLOBE. The Global Land One-kilometer Base Elevation (GLOBE) Project is a 30-arc-second (1-km) gridded, quality-controlled global Digital Elevation Model (DEM).
