How to Create a Point/Polygon Features in Earth Engine?

In Earth Engine, features can be created by geometry using the ee.Geometry() function. The ee.Geometry() function allows you to create various types of geometries such as points, lines, polygons, rectangles, and circles.

Example 01: Creating a point feature using ee.Geometry() function

// Create a point feature
var point = ee.Geometry.Point([-122.084, 37.421]);

// Print the point feature
print(point);

// Define a feature with properties
var pointWithProperties = ee.Feature(point, {name: 'San Francisco'});

Example 02: Creating a polygon feature using ee.Geometry() function
 

// Create a polygon feature
var polygon = ee.Geometry.Polygon(
  [[-122.086, 37.418], [-122.086, 37.422], [-122.082, 37.422], [-122.082, 37.418]]);

// Print the polygon feature
print(polygon);

// Define polygon feature with properties
var polygonWithProperties = ee.Feature(polygon, {name: 'San Mateo'});

Now, we can create a featureCollection combining this two geometry.

// Create a feature collection from the features
var featureCollection = ee.FeatureCollection([pointWithProperties, polygonWithProperties]);

// Print the feature collection
print(featureCollection);
