The default order of the collection is by date. So when you display the collection, it implicitly creates a mosaic with the latest pixels on top. You can call
.mosaic() on an ImageCollection to create a mosaic image from the pixels
at the top.
We can also create a composite image by applying selection criteria to each pixel from all pixels in the stack. Here we use the
median() function to create a composite where each pixel value is the median of all pixels from the
Tip: If you need to create a mosaic where the images are in a specific order, you can use the
.sort()function to sort your collection by a property first.
