Coordinates of Latitude and Longtitude different on Cesium vs real world?

CesiumJS

Hello all,

I am running into a problem that I can't seem to find documentation on. I am trying to center the view around Australia (using the latitude and longitude of Sydney as a basis [-33.865143, 151.209900]).

When I enter those coordinates into

var viewer = new Cesium.Viewer('cesiumContainer');

viewer.camera.setView({
    position : new Cesium.Cartesian3.fromDegrees(-33.865143, 151.209900, 1550.0)
});

the view centers around North America, barely any difference from the normal view that pops up in the "Hello World" example..

I even added a simple console.log at the end to check if all the code was being run and it was.
I suspect that the coordinate system for cesium is vastly different from the real world and I am not sure how to fix that...

Any help would be great.

I also tried the Cartographic way:

viewer.camera.setView({
    positionCartographic : new Cesium.Cartographic(-33.865143, 151.209900, 1550.0)
});

That produced a similar result as the first one.

Hello,

Cesium uses (longitude, latitude), not (latitude, longitude). Switching the coordinates fixes the problem.

Here is your updated example:

var viewer = new Cesium.Viewer(‘cesiumContainer’);
viewer.camera.setView({
destination : new Cesium.Cartesian3.fromDegrees(151.209900, -33.865143, 1550.0)
});

Ah thank you so much!!

I feel a little silly, I see that is noted on the documentation.
