Distance between sites


d = distance(site1,site2) returns the distance in meters between site1 and site2.


d = distance(site1,site2,path) returns the distance using a specified path type, either Euclidean or geodesic.

d = distance(___,Name,Value) returns the distance with additional options specified by name-value pairs.

Create transmitter and receiver sites.

tx = txsite('Name','MathWorks','Latitude',42.3001,'Longitude',-71.3504);
rx = rxsite('Name','Fenway Park','Latitude',42.3467,'Longitude',-71.0972);

Get the Euclidean distance in km between the sites.

dme = distance(tx,rx)
dme = 2.1504e+04
dkm = dme / 1000
dkm = 21.5038

Get the geodesic distance between the two sites.

dmg = distance(tx,rx,'geodesic')
dmg = 2.1504e+04

Input Arguments

collapse all

Transmitter or receiver site, specified as a txsite or rxsite. You can use array inputs to specify multiple sites.

Measurement path type, specified as one of the following:

  • 'euclidean': Uses the shortest path through space that connects the antenna center positions of the site 1 and site 2.

  • 'geodesic': Uses the shortest path on the surface of the earth that connects the latitude and longitude locations of site 1 and site 2. This path uses Earth ellipsoid model WGS-84.

Data Types: char

Name-Value Pair Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: 'Map','siteviewer1'

Map for surface data, specified as a siteviewer object or a terrain name. Valid terrain names are 'none', 'gmted2010', or the name of the custom terrain data added using addCustomTerrain. The default value is the current Site Viewer or 'gmted2010', if none is open.

Data Types: char | string

Output Arguments

collapse all

Distance between sites, returned as M-by-N arrays in degrees. M is the number of sites in site 2 and N is the number of sites in site 1.
