Map.getBounds

  • TheMap.getBounds() method returns the bounds of the current map view.

  • The bounds are returned as a list in the format [west, south, east, north] in degrees by default.

  • Optionally, the bounds can be returned as GeoJSON by setting theasGeoJSON argument totrue.

  • The method returns a GeoJSONGeometry, a list of numbers, or a string depending on theasGeoJSON argument.

Returns the bounds of the current map view, as a list in the format [west, south, east, north] in degrees.

UsageReturns
Map.getBounds(asGeoJSON)GeoJSONGeometry|List<Number>|String
ArgumentTypeDetails
asGeoJSONBoolean, optionalIf true, returns map bounds as GeoJSON.

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.vardefaultMap=Map;// ui.Map objects can be constructed. Here, a new map is declared.varnewMap=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.vargeom=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());
