I am trying to create drop downs that will select features from a feature collection, and have each newly selected feature drawn on the map. I want to have three selectable variables then calculate NDVI for the intersection of the three features. Server side I have managed to filter the feature collections and create a time series of one of the features as seen here:
But I cannot figure out how to create a user environment to select and redraw the selected features. Here, the feature collection layer will disappear when the user selects from the drop down menu, but the feature is not redrawn on the map.
I would like to calculate a new time series each time the user selects a new set of features based on Forest, county, and municipality.
