What is image collection in Google Earth Engine?

An image collection refers to a set of Earth Engine images. For example, the collection of all Landsat 8 images is an ee.ImageCollection . Like the SRTM image you have been working with, image collections also have an ID.

What is masking in Google Earth Engine?

Gets or sets an image’s mask. The output image retains the metadata and footprint of the input image. Pixels where the mask changes from zero to another value will be filled with zeros, or the values closest to zero within the range of the pixel type. Note: the version that sets a mask will be deprecated.

How do you stack images in Gee?

How do I remove an image overlay from Google Earth?

Earth Studio supports multiple overlays in a project at a time. Click the overflow menu for the KML item and select Delete to remove an added overlay from your project.

What is cloud masking?

Cloud Mask (Dense/Cirrus) The cloud mask enables cloudy and cloud-free pixels to be identified. The mask includes both dense clouds and cirrus clouds with an indicator specifying the cloud type. Processing is performed with data sampled at 60 m spatial resolution for all spectral bands.

What is the difference between Google Earth Engine and Google Earth?

Google Earth allows you to see satellite imagery pixels and GEE allows you to perform sophisticated analytics on those satellite imagery pixels. Google Earth Engine (GEE) is a cloud computing platform which enables data scientists to do planetary satellite imagery analysis.
