DAC data file and configure it for use as the official mean sea level surface by the rest of the library. To find a single geoid height, specify lat and lon as scalars. To find a p -by- q grid of geoid heights, specify lat and lon as p -by- q matrices. Referencing vector, returned as a three-element vector of the form [s nlat wlon] with these values: Trial Software Product Updates.

This stream must have the same format as the binary geoid height file described on this page: Do you want to open this version instead? The file must have the same format as the binary geoid height file described on this page: Specify longitude limits in the range [ ] or [0 ].
InvalidDataException – Thrown when the stream terminates unexpectedly before the required terrain data could be read. The output argument refvec is a referencing vector used to associate each geoid height with a latitude and longitude.
It is safe to we15mgh this method from multiple threads simultaneously. First, specify vectors of latitude and qw15mgh values. InvalidDataException – Thrown when the FileStream created from the fileName terminates unexpectedly before the required terrain data could be read. Other MathWorks country sites are not optimized for visits from your location. Create matrices that contain copies of the latitude and longitude vectors using ndgrid. At this resolution, N is a by matrix wd15mgh geoid heights spaced at 15 minute intervals.
To find a p -by- q grid of geoid heights, specify lat aw15mgh lon as p -by- q matrices. Specify latitude and longitude in degrees. For more information, see Geographic Interpretations of Geolocated Grids.
Sample factor, specified as a positive integer. Specify the latitude and ww15mggh limits in degrees. To return the entire grid of geoid heights, specify samplefactor as 1. Geoid height samples are located along latitude—longitude grid lines, as opposed to between the grid lines. ArgumentNullException – Thrown when fileName is null.
Further details can be found here: Grid of Geoid Heights within Limits. Longitude in degrees, specified as a scalar, vector, or matrix. The result is returned in meters. ArgumentNullException – Thrown when stream is null. Find geoid heights from EGM96 by specifying latitude and longitude values in degrees.
View the full grid ww51mgh geoid heights from EGM96 within specified latitude and longitude limits. To find several geoid heights, specify lat and lon as vectors of the same length.

The dimension of lon depends on the dimension of the geoid heights you want to find. Input Arguments collapse all lat — Latitude scalar vector matrix. Gets the interpolated height of sw15mgh terrain at the specified longitude and latitude.
Referencing vector, returned as a three-element vector of the form [s nlat wlon] with these values: Longitude limits, dw15mgh as a two-element vector of the form [westernLimit easternLimit].
You can visualize the geoid as the surface of the ocean without effects such as weather, waves, and land. All Examples Functions More.
