GeoModel class final
A base class for ArcGISMap and ArcGISScene that contains layers and properties and can be displayed in a GeoViewController.
This base class represents the model in a model-view-controller (MVC) architecture, while the GeoViewController represents the view. To display a map or scene to the user, pass GeoModel to its appropriate GeoViewController, as follows:
- Pass an ArcGISMap to an ArcGISMapViewController.
- Pass an ArcGISScene to an ArcGISSceneViewController.
GeoModel has many properties that are common to both maps and scenes. For example:
- Each map or scene typically has a GeoModel.basemap to help orient the users.
- The GeoModel.operationalLayers collection gives you access to the vector data (points, line, polygons), raster data, and attribute information provided by the ArcGISMap or ArcGISScene.
- The GeoModel.spatialReference determines how spatial data relates to real-world space.

Properties
- basemap ↔ Basemap?
-
The basemap for this map or scene.
getter/setter pair
-
bookmarks
→ List<
Bookmark> -
The collection of bookmarks defined for this map or scene.
no setter
- geotriggersInfo → GeotriggersInfo
-
Information about the set of Geotrigger objects defined for the map or
scene.
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- initialViewpoint ↔ Viewpoint?
-
The initial viewpoint when the map or scene is first displayed.
getter/setter pair
- item ↔ Item?
-
The ArcGIS item associated with this map or scene.
getter/setter pair
- loadError → ArcGISException?
-
The load error.
no setterinherited
- loadSettings ↔ LoadSettings
-
The properties that control the default loading and rendering behavior of
feature layers in this map or scene.
getter/setter pair
- loadStatus → LoadStatus
-
The load status.
no setterinherited
-
onBasemapChanged
→ Stream<
Basemap?> -
Callback invoked when the basemap changes.
no setter
-
onLoadStatusChanged
→ Stream<
LoadStatus> -
A stream that reports changes to the LoadStatus.
no setterinherited
-
operationalLayers
→ List<
Layer> -
A collection of layers that can access geographic data from a file or a
service.
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- spatialReference → SpatialReference?
-
The spatial reference for this map or scene.
no setter
-
tables
→ List<
FeatureTable> -
A collection of feature tables in the map or scene. Unlike
GeoModel.operationalLayers, tables are not displayed by the
GeoViewController.
no setter
-
transportationNetworks

scene.
no setter
- unusedJson → String
-
Data from the source JSON that the API did not make use of.
no setter
- version → String
-
The version of the ArcGISMap or ArcGISScene when it is loaded. The
version of a newly created ArcGISMap or ArcGISScene is empty.
no setter
