Just go to usgs web site view the Landsat images and download the required images

Hi,

Google Earth Engine (GEE) team has made a great tutorial explaining the basic functionality of GEE. 

https://developers.google.com/earth-engine/tutorials

Here you will find examples of filtering image collection by cloudcover and other features

Cheers

If I better understand your question, you can download two successive satellite data (Path and row wise) for your study area and just mosaic it. hopefully, it will helpful for your work.

Thanks for the answer, but I need to know how to do this on google earth engine using a JavaScrit code.

Hi, you can sort your images use the key "CLOUD_COVER", I think the following codes is helpful for you.

var menghai_image = ee.ImageCollection("LANDSAT/LE7_L1T_TOA")

                      .filterDate('2000-01-01','2014-12-30')

                      .filterBounds(menghai_point1)

                      .sort('CLOUD_COVER',false)

Hi!

Weiheng Xu mentioned the correct key, but I don't think that sorting would be the best option in this case. I would suggest to define the cloud cover percentage, for example .filterMetadata('CLOUD_COVER', 'less_than', 30)

Cheers

The ImageCollection.first() method is not sufficient by itself for sorting and extracting more than one image. Please look into ee.Array() (https://developers.google.com/earth-engine/arrays_intro). Cast the ImageCollection to an Array and then access the Image IDs via indices.

Dear if you need to download Landsat imagery! you can simply visit USGS website to download image for any place throughout the world and for any time

my regards
