![]() Let featureCollection = FeatureCollection(features) Let pointFeature = Feature(Point(location)) Let geometr圜ollection = Geometr圜ollection(geometries) Let multiPolygonFromLocations = MultiPolygon(locations: arrayOfLocationArrays) // ] Let multiPolygon = MultiPolygon(polygons) Let multiPolylineFromLocations = MultiPolyline(locations: arrayOfLocationArrays) // ] Let multiPolyline = MultiPolyline(polylines) Let pointCollection = PointCollection(locations) Let polygonWithInteriorPolygons = Polygon(locations, interiorPolygons: polygons) The following code shows several ways to create a GeoJSON Feature, FeatureCollection, and geometries. Add GeoJSON feature to the data source. ![]() Create a data source and add it to the map. The following code shows how to create a DataSource, add it to the map, and add a feature to the data source. ![]() Once you have a GeoJSON feature created, a data source can be added to the map through the sources property of the map. Let feature = Feature(Point(CLLocationCoordinate2D(latitude: 45, longitude: -100)), properties: properties) Let feature = Feature(Point(CLLocationCoordinate2D(latitude: 45, longitude: -100)))įeature.addProperty("custom-property", value: "value")Īlternatively the properties can be loaded into a dictionary (JSON) first then passed into the feature when creating it, as the following code demonstrates: //Create a dictionary to store properties for the feature. The following code shows how GeoJSON objects can be created in Azure Maps. Load and store GeoJSON data in the DataSource class and render it using layers. GeoJSON classes available in the Azure Maps iOS SDK to easy create, and serialize GeoJSON data. GeoJSON is an open geospatial standard way for representing geospatial data in JSON format. Ideal for large to massive data sets (millions or billions of shapes).Īzure Maps uses GeoJSON as one of its primary data models. Vector tile source: Loads data formatted as vector tiles for the current map view, based on the maps tiling system.Good for small to medium data sets (upwards of hundreds of thousands of shapes). GeoJSON source: Manages raw location data in GeoJSON format locally.Currently there are two types of data sources: Using data sources optimizes the data operations for querying and rendering. The Azure Maps iOS SDK stores data in data sources.
