## Visualizing geometries

To visualize a geometry, add it to the map. For example:

### Code Editor (JavaScript)

```javascript
// Create a geodesic polygon.
var polygon = ee.Geometry.Polygon([
  [[-5, 40], [65, 40], [65, 60], [-5, 60], [-5, 60]]
]);

// Create a planar polygon.
var planarPolygon = ee.Geometry(polygon, null, false);

// Display the polygons by adding them to the map.
Map.centerObject(polygon);
Map.addLayer(polygon, {color: 'FF0000'}, 'geodesic polygon');
Map.addLayer(planarPolygon, {color: '000000'}, 'planar polygon');
```

For more on visualizing, see [Feature and
FeatureCollection Visualization](https://developers.google.com/earth-engine/guides/feature_collections_visualizing).

## Geometry information and metadata

To view information about a geometry, print it. To access the information
programmatically, Earth Engine provides several methods. For example, to get information
about the polygon created previously, use:

### Code Editor (JavaScript)

```javascript
print('Polygon printout: ', polygon);

// Print polygon area in square kilometers.
print('Polygon area: ', polygon.area().divide(1000 * 1000));

// Print polygon perimeter length in kilometers.
print('Polygon perimeter: ', polygon.perimeter().divide(1000));

// Print the geometry as a GeoJSON string.
print('Polygon GeoJSON: ', polygon.toGeoJSONString());

// Print the GeoJSON 'type'.
print('Geometry type: ', polygon.type());

// Print the coordinates as lists.
print('Polygon coordinates: ', polygon.coordinates());

// Print whether the geometry is geodesic.
print('Geodesic? ', polygon.geodesic());
```

Observe that the perimeter (or length) of a geometry is returned in meters and the
area is returned in square meters unless a projection is specified. By default, the
computation is performed on the WGS84 spheroid and the result is computed in meters or
square meters.
