elevation

Elevation of site

Syntax

z = elevation(site)

z = elevation(site,Map=map)

Description

z = elevation(site) returns the ground or building surface elevation of antenna site in meters. Elevation is measured relative to mean sea level using earth gravitational model, EGM-96. If the site coincides with a building, elevation is measured at the top of the building. Otherwise, elevation is measured at the ground.

This function only supports antenna sites with a CoordinateSystem property value of 'geographic'.

z = elevation(site,Map=map) specifies the map to use when calculating the elevation of the site.

Examples

Elevation at Mount Washington

Compute and display the elevation at Mount Washington in meters.

mtwash = txsite('Name','Mt Washington','Latitude',44.2706, ...
       'Longitude',-71.3033);
z = elevation(mtwash)

z = 1.8704e+03

Input Arguments

site — Transmitter or receiver site

txsite or rxsite object | array of txsite or rxsite objects

Transmitter or receiver site, specified as a txsite or rxsite object or an array of txsite or rxsite objects.

map — Map for visualization or surface data

siteviewer object | string scalar | character vector

Map for visualization or surface data, specified as one of the following:

• A siteviewer object.¹

• A terrain name if the function is called with an output argument. Valid terrain names are "none", "gmted2010", or the name of the custom terrain data added using addCustomTerrain.

The default value is:

• The current siteviewer object or a new siteviewer object if none are open.

• "gmted2010" if called with an output.

Data Types: char | string

Output Arguments

z — Ground or building surface elevation of antenna site

M-by-1 matrix

Ground or building surface elevation of the antenna site, returned as an M-by-1 matrix with each element unit in meters. M is the number of sites in site.
