Map Services¶

The static class FDOT.GIS.Client.Domain.Gis.MapHandler gives the developer access to the map services that are currently loaded into the application.

Name	Type	Descriptions
BaseMaps	ReadOnlyObservableCollection<MapService>	Contains all of tiled MapServices
DynamicLayers	ReadOnlyObservableCollection<MapService>	Contains all of the dynamic mapservices
Layers	ReadOnlyObservableCollection<MapService>	All of the MapServices currently loaded in the application
FlattenedLayers	ReadOnlyObservableCollection<DisplayLayer>	Flattens all of the layers in the mapservice that are grouped into a single list
QueryableLayers	ReadOnlyObservableCollection<DisplayLayer>	All of the layers that have been configured as queryable

The FDOT.GIS.Client.Domain.Gis.MapService class represents an ArcGis Server MapService that has been configured for the Virtual Applications.

Name	Type	Description
AlternateIdentifyServiceName	string	The name of an alternative map service to use for identifying if the current mapservice does not support identify.
InitializationFailed	bool	Indicates if the map service initialization failed.
IsQueryable	bool	Returns if the map service can be queried.
IsViewable	bool	Returns if the map service can be viewed.
IsVisible	bool	Return if the map service is currently visible on the map.
Layers	ReadOnlyObservableCollection<DisplayLayer>	Returns the layers in the MapService
MapServiceName	string	The name of the MapService
Name	string	The configured name of the MapService
Opacity	double	The opacity of the mapservice on the map.
Url	string	The url of the map service.
Visible	bool	The visibility of the map service on the map.

Name	ReturnType	Description
LoadSwatches()	void	Loads the swatches for the layers in the map service.

Through the MapHandler class developers can pan and zoom to features on the map.

Name	ReturnType	Description
GetExtent()	Geometry	Returns the current extent of the map
PanToGeometry(Geometry geometry)	void	Pans the map to geometry
SetExtent(DataContracts.Geometry envelope)	void	Sets the current extent of the map.
Zoom(double zoomFactor)	void	Zooms the map by the provided zoom factor.
ZoomToGeometry(Geometry geometry)	void	Zooms the map to the provided Geometry.

 var geoPnt = new DataContracts.Geometry {X = Longitude, Y = Latitude};

The Framework has built in functionality for the selection of geometry from a user. Geometry
