Returns the number of elements in the collection.
| Usage | Returns | ImageCollection.size() | Integer |
| Argument | Type | Details | this: collection | FeatureCollection | The collection to count. |
Examples
Code Editor (JavaScript)
// Note: ee.ImageCollection.size may take a lot of time and memory to run,
// since it must generate all of the results in order to count them. Large
// collections and/or complex computations can produce memory limitation
// errors.
// A Landsat 8 TOA image collection (1 year of images at a specific point).
var col = ee.ImageCollection('LANDSAT/LC08/C02/T1_TOA')
.filterBounds(ee.Geometry.Point(-90.70, 34.71))
.filterDate('2020-01-01', '2021-01-01');
// Get the number of images in the collection.
print('Number of images', col.size());
