This query is very simple and doesn't need users to enter any inputs.
Step 1: Check on or off the boxes in front of the layers so that only "CAFO Dairy" and "County" are selected. You can select more layers if you want. However, the map will be cleaner and easier to read by checking off those unnecessary layers. Be sure to press "Apply" afterward to make the changes effective.
Step 2: Click on the button - "Query" to run it. The results will be displayed in the area under the map (see image below). If you want to keep the querying result, for Windows XP users, you can right click anywhere in that section and export to Microsoft Excel.
