Add a set of continuous constraints

In the interests of time, this exercise skips manual entry and pastes a full layer card with a rich set of constraints already configured.

1. Add a new layer card and call it temp for now.

2. Open the per-layer {JSON} editor and replace its contents with the entire JSON below:

3. Apply the changes. You will now have a layer called Austria Wind Power Density at 100m.

4. Explore the Constraints tab of the new layer to see how each of the continuous, combined and categorical constraints is configured.

Did you remember to export?

That's the last of the workshop — but a good final export never hurts.

Congratulations — you've built a complete Geospatial Explorer configuration from scratch!
