I'm tasked with displaying reserve data on a map but also displaying the category data for each site even though they overlap with other reserves. E.g. I have a category, "Birdwatching" which applies to 50 sites whilst the category, "Grassland" applies to 30 sites but overlaps with the birdwatching category thus a site could have "birdwatching and grasslands".
I created a layer for every category, so a user could select "birdwatching" and view the 50 of 100 reserves that meet this rule. But how do I go about composing a map that includes all ten categories?
