1. Import and create map

• Click on CREATE MAP.

2. Layers and styles

2. 1. Ordering of the layers in the Builder

• Change the basemap to the Dark Matter (labels below) basemap and check the different basemaps options.

• Note how the layer we added gets the A0 identifier. This is not important now but it will be later when adding analysis and widgets.

2. 2. Layer options

• DATA:
  • This interface gives a general view of the fields the layer, its name and its data type but also from there you can add them as widgets.
  • Use the slider button to switch from VALUES to SQL. The SQL view allows more advanced users to manage data in a more precise way.
  • Finally, use the button in the bottom left corner of the map to switch between Data view and Map view.
