height

Height of surface in tracking scenario

Description

example

h = height(surface,positions) returns the heights of the surface at the specified positions.

Examples

collapse all

Create a tracking scenario object.

scene = trackingScenario;

Specify the terrain as magic(4) and define the boundary of the terrain as a square.

terrain = magic(4)
terrain = 4×4

    16     2     3    13
     5    11    10     8
     9     7     6    12
     4    14    15     1

boundary = [0 100; 0 100];

Create the ground surface and add it to the scenario.

surface = groundSurface(scene,Terrain=terrain,Boundary=boundary)
surface = 
  GroundSurface with properties:

            Terrain: [4x4 double]
    ReferenceHeight: 0
           Boundary: [2x2 double]

Get the heights of the surface at the center and its four corners.

h0 = height(surface,[50 50]')
h0 = 8.5000
h1 = height(surface,[0 0]')
h1 = 16
h2 = height(surface,[100 0]')
h2 = 13
h3 = height(surface,[0 100]')
h3 = 4
h4 = height(surface,[100 100]')
h4 = 1

Input Arguments

collapse all

Ground surface, specified as a GroundSurface object.

Positions of the surface to query, specified as a 2-by-N matrix of real values or a 3-by-N matrix of real values, where N is the number of positions.

If the IsEarthCentered property of the tracking scenario is specified as:

  • false — Each column of a 2-by-N matrix represents the x- and y-coordinates of a position in meters. Each column of a 3-by-N matrix represents the x-, y-, and z-coordinates of a position in meters. Note that the z-coordinate is irrelevant for surface height querying.

  • true — Each column of the 2-by-N matrix represents the latitude and longitude of a position in degrees, in the geodetic frame. Each column of the 3-by-N matrix represents the latitude in degrees, longitude in degrees, and altitude in degrees of a position, in the geodetic frame. Note that the altitude is irrelevant for surface height querying.

Output Arguments

collapse all

Heights of queried positions, returned as an N-element vector of real values in meters, where N is the number of queried positions.
