ee.FeatureCollection.aside

  • The aside() function calls a given function with the object itself as the first argument and returns the object for chaining.

  • It's useful for debugging and inspecting objects at different stages of a chained operation.

  • The aside() function can accept additional arguments to pass to the function being called.

  • The example demonstrates using aside() to print a FeatureCollection and add it to the Map in the Google Earth Engine Code Editor.

Calls a function passing this object as the first argument, and returning itself. Convenient e.g. when debugging:

var c = ee.ImageCollection('foo').aside(print)

.filterDate('2001-01-01', '2002-01-01').aside(print, 'In 2001')

.filterBounds(geom).aside(print, 'In region')

.aside(Map.addLayer, {min: 0, max: 142}, 'Filtered')

.select('a', 'b');

Returns the same object, for chaining.

Examples

Code Editor (JavaScript)

// Get a FeatureCollection of power plants in Belgium. Use "aside" to print the
// collection and display it on the Map.
var fc = ee.FeatureCollection('WRI/GPPD/power_plants')
             .filter('country_lg == "Belgium"')
             .aside(print, 'Power plants in Belgium')
             .aside(Map.centerObject, 7)
             .aside(Map.addLayer, {color: 'blue'}, 'Power plants');
