I am looking to create an interactive map with the ability to toggle layers.
Is it possible to modify fusion table info based on a user-set value?
For example, I need to map the counties near Erie County, NY. I need Erie County to be on one layer and Erie County to be colored Red when the layer is turned on. I also need all counties within 15 miles on another layer, with those counties being colored Yellow when that layer is turned on. (The counties within 15 miles of Erie County include Cattaraugus, Chautauqua, Genesee, Niagara, Wyoming, Orleans and Allegany Counties in New York.)
In the future, I might need to include other counties in the yellow layer. For example, I might need all counties within 25 miles to be included (which would then also include Livingston and Monroe Counties in New York).
Is there a way to have all of the counties within 50 miles of Erie County in my fusion table, but only use the counties that are less than a user-determined value? (The default would be set to 15 miles, but the user would be given the opportunity to change that value to any number between 0-50 miles.)
