Is there a way to add properties to a feature in the Gee?

Is there a way to add a property to a feature in the GEE. I know that you can edit existing properties with set (), but haven’t found a way to add a property. Thanks for contributing an answer to Geographic Information Systems Stack Exchange! Please be sure to answer the question.

How to map over a featurecollection in Google Earth?

// Get the centroid of the feature’s geometry. // Return a new Feature, copying properties from the old Feature. // Map the centroid getting function over the features. // Display the results. Note that only a subset of properties is propagated to the features in the new collection.

How to create a feature in Earth Engine?

A Feature in Earth Engine is defined as a GeoJSON Feature. Specifically, a Feature is an object with a geometry property storing a Geometry object (or null) and a properties property storing a dictionary of other properties. To create a Feature, provide the constructor with a Geometry and (optionally) a dictionary of other properties.

How to add another attribute to a featurecollection?

To apply the same operation to every Feature in a FeatureCollection, use featureCollection.map (). For example, to add another area attribute to every feature in a watersheds FeatureCollection, use:

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 count the number of features in Google Earth?

You can use the aggregation shortcuts to count the number of features or summarize an attribute: // Load watersheds from a data table. // Filter to the continental US. // Convert ‘areasqkm’ property from string to number. // Display the table and print its first element. // Print the number of watersheds.

What are the Constructors in Google Earth Engine?

The ee.String () and ee.Number () methods are constructors. A constructor takes its argument (and possibly other parameters), puts it in a container, and returns the container and its contents as an Earth Engine object that you can manipulate in your code. Any constructor starting with ee returns an Earth Engine object.
