I want to map a function over a Feature Collection to extract some column values and turn it into a list.

I do know how to map a function over collections, but I'm new with Google Earth Engine and I don't know very well javascript, so I don't know how to work with lists and other features from this language.

  • What is the script that you tried out?

Try calling .aggregate_array('property'), this returns an array of values of the selected property.
