I love these kinds of map notebooks!

One small note: my longitude is -122.84034278116127 and my latitude is 38.06118958261439, which your inputs don't seem to accept. I changed the range of the inputs and got it to work, but thought I'd mention it to you in case I'm missing something fundamental and you have a better solution.

Hi Dunstan, they should be able to accept those values, but I have the sliders rounded off to the nearest 1/10 as it grabs the nearest tile. Can I ask what you had to change the range of the inputs to in order for it to work for you?

Oh, right, that totally makes sense. I just removed the `step` from the input, but of course I could have just entered a less precise value, such as -122.8, 38.1. Somehow that never occurred to me, even though I work here. That's ridiculous! Sorry!

I'm getting runtime errors ("demData could not be resolved") for zoom levels above 14.

I'd suggest to control the auto rotation angle via a uniform, so that you can pause the rotation while the terrain is being dragged.
