Get/set geoglobe view angle

With non-GeographicAxes, camva() can be used to get/set camera viewing angle. This doesn't seem possible for uifigure+geoglobe figures. Is there a way to at least get the viewing angle? The purpose is to simulate what a camera with a particular lens would see.

Thanks I think Campos doesn't have a way to get/set view angle in degrees

I think this might turn into a feature request to have `camva()` work on GeographicAxes

If you would like to control the camera viewing angle or zoom level, "camheight" can be used to achieve a similar effect. Could you share a usecase where "camheight" cannot be used?

The angular field of view of the camera is not the same thing as the height of the camera. Please see 'camva' and associated documentation for explanaition of what were looking for. The geoglobe does not currently support this functionality, which is unfortunate.

I would also like to see this feature implemented. I don't understand why this was overlooked. camheight cannot reproduce the view angle. The geoglobe map is an amazing feature, but I cannot use it until camva is added. It would likely be an easy add.

Hi @scivision,

Below are some of the MATLAB functions that might help to get/set camera viewing angles.

• "campitch" - Set or query pitch angle of camera for Site Viewer https://www.mathworks.com/help/comm/ref/siteviewer.campitch.html
• "camheading" - Set or query heading angle of camera for Site Viewerhttps://www.mathworks.com/help/comm/ref/siteviewer.camheading.html

You can also use the "camroll" function to rotate the camera about view axis.
