How are date objects represented in Earth Engine?

How are date objects represented in Earth Engine?

Date objects are the way Earth Engine represents time. As in the previous examples, it is important to distinguish between a JavaScript Date object and an Earth Engine ee.Date object. Construct an ee.Date from a string, from a JavaScript Date, or using static methods provided by the ee.Date class.

How to initialize the Google Earth Engine object?

At construction time, you can use JavaScript functionality to initialize the Earth Engine object. In this case an ee.Dictionary is constructed directly from a JavaScript literal object: // Make a Dictionary on the server. // Get some values from the dictionary.

How to map an imagecollection in Google Earth?

For example: // Load a Landsat 8 collection for a single path-row. // the solar elevation > 40 degrees. Otherwise it returns a zero image. // Map the function over the collection, convert to a List and print the result.

How to get metadata from Google Earth Engine?

// Get scale (in meters) information from band 1. // Note that different bands can have different projections and scale. // Get a list of all metadata properties. // Get a specific metadata property. // Get version number (ingestion timestamp as microseconds since Unix epoch). // Get the timestamp and convert it to a date.

How to use ee.number in Earth Engine?

You have to use the equivalent method defined for an ee.Number: // Use a built-in function to perform an operation on the number. In this example, log () is a method for a ee.Number object. (Use the Docs tab at the left side of the code editor to see a list of all the methods for every Earth Engine object type, for example ee.Number > log ()).

How to send JavaScript objects to Earth Engine?

Now that you’re comfortable with JavaScript, learn how to put JavaScript objects and primitives into Earth Engine containers for sending to the server and processing at Google. For example, define a string, then put it into the ee.String () container to be sent to Earth Engine: // Define a string, then put it into an EE container.
