enu2geodetic

Local Cartesian ENU to geodetic

Syntax

  • [lat,lon,h] = enu2geodetic(xEast,yNorth,zUp,lat0,lon0,h0,spheroid)
  • [___] = enu2geodetic(___,angleUnit)

Description

[lat,lon,h] = enu2geodetic(xEast,yNorth,zUp,lat0,lon0,h0,spheroid)) returns geodetic coordinates corresponding to coordinates xEast, yNorth, zUp in a local east-north-up (ENU) Cartesian system. Any of the first six numeric input arguments can be scalar, even when the others are nonscalar; but all nonscalar numeric arguments must match in size.

[___] = enu2geodetic(___,angleUnit) adds angleUnit which specifies the units of inputs lat0, lon0, and outputs lat, lon.

Input Arguments

collapse all

x-coordinates of one or more points in the local ENU system, specified as a scalar value, vector, matrix, or N-D array. Values must be in units that match the LengthUnit property of the spheroid input.

Data Types: single | double

y-coordinates of one or more points in the local ENU system, specified as a scalar value, vector, matrix, or N-D array. Values must be in units that match the LengthUnit property of the spheroid input.

Data Types: single | double

z-coordinates of one or more points in the local ENU system, specified as a scalar value, vector, matrix, or N-D array. Values must be in units that match the LengthUnit property of the spheroid input.

Data Types: single | double

Geodetic latitude of local origin (reference) point(s), specified as a scalar value, vector, matrix, or N-D array. In many cases there is one origin (reference) point, and the value of lat0 is scalar, but it need not be. (It may refer to a moving platform, for example). Values must be in units that match the input argument angleUnit, if supplied, and in degrees, otherwise.

Data Types: single | double

Longitude of local origin (reference) point(s), specified as a scalar value, vector, matrix, or N-D array. In many cases there is one origin (reference) point, and the value of lon0 is scalar, but it need not be. (It may refer to a moving platform, for example). Values must be in units that match the input argument angleUnit, if supplied, and in degrees, otherwise.

Data Types: single | double

Ellipsoidal height of local origin (reference) point(s), specified as a scalar value, vector, matrix, or N-D array. In many cases there is one origin (reference) point, and the value of h0 is scalar, but it need not be. (It may refer to a moving platform, for example). Units are determined by the LengthUnit property of the spheroid input.

Data Types: single | double

Reference spheroid, specified as a referenceEllipsoid, oblateSpheroid, or referenceSphere object. Use the constructor for one of these three classes, or the wgs84Ellipsoid function, to construct a Mapping Toolbox spheroid object. You can not directly pass in the name of your spheroid. Instead, pass that name to referenceEllipsoid or referenceSphere and use the resulting object.

Units of angles, specified as ‘degrees' (default), or 'radians'.

Data Types: char

Output Arguments

collapse all

Geodetic latitudes of one or more points, returned as a scalar value, vector, matrix, or N-D array. Units are determined by the input argument angleUnit, if supplied; values are in degrees, otherwise. When in degrees, they lie in the closed interval [-90 90].

Longitudes of one or more points, returned as a scalar value, vector, matrix, or N-D array. Units are determined by the input argument angleUnit, if supplied; values are in degrees, otherwise. When in degrees, they lie in the interval [-180 180].

Ellipsoidal heights of one or more points, returned as a scalar value, vector, matrix, or N-D array. Units are determined by the LengthUnit property of the spheroid object
