Code Editor (JavaScript)
// Get Denver county polygon.
var denver = ee.FeatureCollection('FAO/GAUL_SIMPLIFIED_500m/2015/level2')
.filter("ADM2_NAME == 'Denver'")
.filter(ee.Filter.eq('ADM2_NAME', 'Denver')) // Exactly the same as above.
.first()
.geometry();
Map.centerObject(denver, 9);
Map.addLayer(denver, null, 'Denver');
