Height of surface in tracking scenario
Obtain Height of Ground Surface
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
positions — Positions of surface to query
2-by-N matrix of real values | 3-by-N matrix of real values
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.
IsEarthCentered property of the tracking scenario is
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.
h — Heights of queried positions
N-element vector of real values
Heights of queried positions, returned as an N-element vector of real values in meters, where N is the number of queried positions.
