Stay organized with collections
Save and categorize content based on your preferences.
An imperative function that returns a map ID and optional token, suitable for generating a Map overlay.
Returns an object which may be passed to ee.data.getTileUrl or ui.Map.addLayer, including an additional 'image' field, containing a Collection.draw image wrapping a FeatureCollection containing this feature. Undefined if a callback was specified.
| Usage | Returns | FeatureCollection.getMapId(visParams, callback) | MapId|Object |
| Argument | Type | Details | this: featurecollection | FeatureCollection | The FeatureCollection instance. |
visParams | Object, optional | The visualization parameters. Currently only one parameter, 'color', containing an RGB color string is allowed. If visParams is not specified, black ("000000") is used. |
callback | Function, optional | An async callback. |
