Map.centerObject

Centers the map view on a given object.

Returns the map.

Usage	Returns
`Map.centerObject(object, zoom, onComplete)`	ui.Map

Argument	Type	Details
`object`	Element\|Geometry	An object to center on - a geometry, image or feature.
`zoom`	Number, optional	The zoom level, from 0 to 24. If unspecified, computed based on the object's bounding box.
`onComplete`	Function, optional	A callback which is triggered after the recentering completes successfully. Passing this parameter causes the `centerObject` operation to run asynchronously.

Examples

Code Editor (JavaScript)

// The default map in the Code Editor is a built-in ui.Map object called "Map".
// Let's refer to it as "defaultMap" for clarity.
var defaultMap = Map;

// ui.Map objects can be constructed. Here, a new map is declared.
var newMap = ui.Map({
  center: {lat: 0, lon: 0, zoom: 1},
  style: {position: 'bottom-right', width: '400px'}
});

// Add the newMap to the defaultMap.
defaultMap.add(newMap);

// You can set the viewport of a ui.Map to be centered on an object.
// Here, the defaultMap is centered on a point with a selected zoom level.
var geom = ee.Geometry.Point(-122.0841, 37.4223);
defaultMap.centerObject(geom, 18);
defaultMap.addLayer(geom, {color: 'orange'}, 'Googleplex');

// Map extent can be fetched using the ui.Map.getBounds method.
print('defaultMap bounds as a list',
      defaultMap.getBounds());
print('defaultMap bounds as a dictionary',
      ee.Dictionary.fromLists(['w', 's', 'e', 'n'], defaultMap.getBounds()));
print('defaultMap bounds as GeoJSON',
      defaultMap.getBounds({asGeoJSON: true}));

// Map center point can be fetched using the ui.Map.getCenter method.
print('defaultMap center as a Point geometry', defaultMap.getCenter());

// Map zoom level can be fetched using the ui.Map.getZoom method.
print('defaultMap zoom level', defaultMap.getZoom());

// Map scale can be fetched using the ui.Map.getScale method.
print('defaultMap approximate pixel scale', defaultMap.getScale());
