How to dynamically create POI points by latitude and longitude?

How to dynamically create POI points by latitude and longitude?(Cesium for Unreal)

Hi @Xiaoguang,

Can you explain more about what you mean by POI points?

It is the coordinate point in OSM, (point). Used to display the location information of a building and the like.

Or it can be understood as creating an Actor in the world through latitude and longitude.
I want to convert (the Actor’s latitude and longitude) - (Georeference’s latitude and longitude) into world coordinates. But I don’t know this conversion formula, is there any reference?

More specific example:
I want to add a cube by latitude and longitude in the scene of 02_CesiumMelbourne. For example, the coordinates are (-37.81972244489548, 144.98343885201184), then how do I create this cube?
Google Map

I found this and it has been resolved.
