ee.FeatureCollection.aggregate_max
Stay organized with collections
Save and categorize content based on your preferences.
Aggregates over a given property of the objects in a collection, calculating the maximum of the values of the selected property.
| Usage | Returns | FeatureCollection.aggregate_max(property) | |
| Argument | Type | Details | this: collection | FeatureCollection | The collection to aggregate over. |
property | String | The property to use from each element of the collection. |
Examples
Code Editor (JavaScript)
// FeatureCollection of power plants in Belgium.
var fc = ee.FeatureCollection('WRI/GPPD/power_plants')
.filter('country_lg == "Belgium"');
print('Max of power plant capacities (MW)',
fc.aggregate_max('capacitymw')); // 2910
Python setup

fc = ee.FeatureCollection('WRI/GPPD/power_plants').filter(
'country_lg == "Belgium"')
print('Max of power plant capacities (MW):',
fc.aggregate_max('capacitymw').getInfo()) # 2910
