Step 1 – Add WFS Service Connection

• Launch ArcPro and open Catalog window.
• Create New Map
• Add New WFS Server Connection

Step 2 - Establish Connection

• For server URL set WFS Connection/URL enter connection string for the desired WFS. For example, for the last 7 day WFS services for the continental US and Hawaii use https://firms.modaps.eosdis.nasa.gov/mapserver/wfs/USA_contiguous_and_Hawaii/<YOUR_MAP_KEY>/? where ‘YOUR_MAP_KEY’ is the unique code containing both letters and numbers
  (make sure '/?' is included at the end of your WFS URL).
• Click OK

Step 3 - View FIRMS Layers

• If connection was successful, there will be a list of FIRMS WFS service feature layers.
• Open the tree structure under Servers → firms.modaps.eosdis.nasa.gov.wfs to see the WFS the feature type layers.
• Find the layer of interest and drag into your Map Project (ex. NOAA-20 7 days fires).

Step 4 - Draw FIRMS Layer

• Drag the layer of interest into the desired ArcPro map window.
• The layer will be added to your window and draw.
• Position the layer accordingly in the draw order so it is visible with other layers.

Step 5 - Open Layer Symbology Window

• Right click on the FIRMS layer.
• Click on Symbology.

Step 6 - Set Layer Symbology Parameters

• Configure the symbology as desired. Active fire detections can all be symbolized using a single symbol or they can be classified and symbolized uniquely or as graduated symbols based on feature layer attribute values.
• Click OK button to assign the desired symbology scheme.

Step 7 - View Results

• The map will display using your custom symbology.
