Centers the map view on a given object.

Returns this ui.Map.

Map.centerObject(object, zoom, onComplete)ui.Map
this: ui.mapui.MapThe ui.Map instance.
objectElement|GeometryAn object to center on - a geometry, image or feature.
zoomNumber, optionalThe zoom level, from 0 to 24. If unspecified, computed based on the object's bounding box.
onCompleteFunction, optionalA callback which is triggered after the recentering completes successfully. Passing this parameter causes the

centerObject operation to run asynchronously.

// 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},

// 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.
