7-3. Add the wind power layer

Before adding constraints we need something to constrain. In this step we build a single COG layer showing wind power density at 100 m over Austria.

1. In the Layers tab, add a new Interface Group called Energy, then Add layer inside it and name the layer Austria Wind Power Density at 100m.

2. Add a COG data source with this URL:

   https://eox-gtif-public.s3.eu-central-1.amazonaws.com/DHI/PowerDensity_100m_Austria_WGS84_COG_clipped_3857_fix.tif
   

3. Open Data Visualisation → Colormaps → Edit and add a colormap:

   Setting	Value
   Name	jet
   Min	0
   Max	2000
   Steps	50
   Reverse	off

4. In the layer card Controls, enable:

   • Opacity slider
   • Zoom to centre
   • Constraint slider

   Leave Temporal controls and Blend controls unchecked, then close the dialogue.

   Constraint slider

   Without the Constraint slider control the constraints you add in the remaining steps of this tutorial will be saved to the configuration but will never appear in the viewer.

5. To avoid you having to constantly zoom for the rest of this tutorial, go to Settings → Navigation and pick Austria from the quick location list.

6. Open Preview and toggle the layer on. You should see a jet colour ramp over Austria with a gradient legend, and a Filter icon in the layer card, which looks like a funnel.

7. Click on the filter, then drag the slider values. See how this affects the display of the wind power layer.

   

8. Optional — polish the layer and the start location.

   In the layer Metadata, set:

   • Description — copy in the following text:

     The wind power density (w m 2) is a measure of the available wind
     resource at 100 metres height. Higher wind power density indicates
     greater wind power potential. Constraints allow the data to be filtered
     by multiple criteria.
     

   • Units — w / m 2
