Procedures, Data Sources and Analysis. For example when considering the isostatic equilibrium of continents, the density differences between all rock types can be neglected, but not between rock and ice. Downsampling of Topographic Data. Suitable color tables can be found here: This can be done using the following script which assumes input and output are gzip-compressed: Color Tables for Paraview. This grid was shifted 28 m vertically to be consistent with mean sea level before use in building ETOPO1.

ETOPO1 Global Relief Model

Thus, the conversion is trivial:. They were also used to clip some data sets to the coastline to eliminate anomalous values. In this case it makes sense to convert the ice sheets to a rock layer with an equivalent density, i. Document Actions Send this Print this. Using Topography in Etopo1.hrd. For example when considering the isostatic equilibrium of continents, the density differences between all rock etipo1.grd can be neglected, but not between rock and ice.

However, for some application neither dataset is suited. Exaggerated Topography in Paraview.

This can be done using the following script which assumes input and output are gzip-compressed: This integrated bathymetric-topographic grid was extracted at 15 arc-seconds for use in building ETOPO1. It was created by combining topographic data sets from U.

Personal tools Log in. This grid was shifted 28 m vertically to be consistent with mean sea level before use in building ETOPO1.

Measured and Estimated Seafloor Bathymetry This database is a 1 arc-minute global relief model with bathymetry derived from sea-surface satellite altimetry measurements and ocean soundings; topography is derived from GTOPO The database is managed by the Scientific Etopo1.gr on Antarctic Research.

This grid is not currently available to the public, though all of the multibeam swath sonar etopo.1grd data can be obtained from NCEI's multibeam bathymetry database.

ETOPO1 Data Sources

Thus, the conversion is trivial: The data have undergone extensive processing and are free of internal inconsistencies such as erratic points and crossing segments. Topography by Texture Mapping. ETOPO1 utilizes bathymetry extracted from an older version of ftopo1.grd estimated seafloor grid. A distinctive feature of ETOPO1 is the availability of two different datasets, one with polar ice sheets and one without.

Using Topography in Paraview. ETOPO1 was built in two versions: Color Tables for Paraview.

Climate Zones from Topography. This can be done using the following script which assumes input and output are gzip-compressed:. The Caspian Sea data were shifted vertically to mean sea level to be consistent with the other data sets. Procedures, Data Sources and Analysis.
