camposm

Set camera position for axesm-based map using geographic coordinates

Syntax

camposm(lat,long,alt) [x,y,z] = camposm(lat,long,alt)

Description

camposm(lat,long,alt) sets the axes CameraPosition property of the current axesm-based map to the position specified in geographic coordinates. The inputs lat and long are assumed to be in the angle units of the current axesm-based map.

[x,y,z] = camposm(lat,long,alt) returns the camera position in the projected Cartesian coordinate system.

Figure contains an axes object. The hidden axes object contains 3 objects of type surface, line.

Control the view by specifying the camera target, camera up vector, camera position, and camera view angle.

Specify the camera target and the camera up vector using a point near northern Australia.
Specify the camera position using a point near New Zealand. Specify the camera height as one Earth radius above Earth.
Specify the field of view by setting the CameraViewAngle property of the axes.
