Hi there,

I’m not sure what your input data is, but I would take a look at this thread for how to use custom imagery on the globe surface,

We also recently added custom material support for the globe which would be another way to accomplish a similar effect.

Thanks,

Gabby

Hi Tony,

Since you already have the data drawn to an HTML canvas, you should be able to use that on the globe surface. However, you will probably need to create your own ImageryProvider to display and update it. We don’t have instructions on how to do that, but looking at GridImageryProvider.js is a good place to look for an example of an imagery provider that uses the canvas.

Thanks,

Gabby
