AI-generated Key Takeaways
-
The
toBands()method converts an ImageCollection into a single multi-band Image. -
Output band names are created by combining the original band name with the image id from the collection.
-
The maximum number of bands in the resulting image is 5000.
-
The order of bands in the output image is determined by the order of images in the input collection.

// A Landsat 8 TOA image collection (2 months of images at a specific point). var col = ee . ImageCollection ( 'LANDSAT/LC08/C02/T1_TOA' ) . filterBounds ( ee . Geometry . Point ( - 90.70 , 34.71 )) . filterDate ( '2020-07-01' , '2020-09-01' ) . select ( 'B[4-5]' ); // Get NIR and SWIR1 bands only. print ( 'Collection' , col ); // Convert the image collection to a single multi-band image. Note that image ID // ('system:index') is prepended to band names to delineate the source images. var img = col . toBands (); print ( 'Collection to bands' , img ); // Band order is determined by collection order. Here, the collection is // sorted in descending order of the date of observation (reverse of previous). var bandOrder = col . sort ( 'DATE_ACQUIRED' , false ). toBands (); print ( 'Customized band order' , bandOrder );
