Auf dieser Seite wird beschrieben, wie Sie geografische Daten im GeoJSON-Format rendern können.
Format, mit GMUGeoJSONParser, in
zusammen mit GMUGeometryRenderer. GeoJSON ist eine beliebte
für das Rendern geografischer Daten wie Punkte, Linien und Polygone verwenden.

GeoJSON-Daten rendern
Wenn Sie GeoJSON-Daten auf einer Karte rendern möchten, erstellen Sie eine GMUGeoJSONParser mit
Pfad zu einer GeoJSON-Ressource (GeoJSON_sample.kml in diesem
) Erstellen Sie dann ein GMUGeometryRenderer und übergeben Sie den
GMUKMLParser-Instanz. Rufen Sie schließlich
GMUGeometryRenderer.render() Das folgende Codebeispiel zeigt,

Finally, the `GMUGeometryRenderer.render()` method is called to display the GeoJSON data, such as points, lines, and polygons, on the map.\n"],null,["Select platform: [Android](/maps/documentation/android-sdk/utility/geojson \"View this page for the Android platform docs.\") [iOS](/maps/documentation/ios-sdk/utility/geojson \"View this page for the iOS platform docs.\") [JavaScript](/maps/documentation/javascript/datalayer \"View this page for the JavaScript platform docs.\")\n\nThis page shows you how to render geographic data in the GeoJSON\nformat, using `GMUGeoJSONParser`, in\nconjunction with `GMUGeometryRenderer`. GeoJSON is a popular\nformat for rendering geographic data such as points, lines, and polygons.\n\nPrerequisites and notes\n\n`GMUGeoJSONParser` is part of\nthe [Maps SDK for iOS Utility Library](https://github.com/googlemaps/google-maps-ios-\nutils). If you haven't yet set up\nthe library, follow the [setup guide](/maps/documentation/ios-\nsdk/utility/setup) before reading the rest of this page.\n\nFor the full code sample, see the sample apps\n[on\nGitHub](https://github.com/googlemaps/google-maps-ios-utils).\n\nRendering GeoJSON data\n\nTo render GeoJSON data on a map, create a `GMUGeoJSONParser` with\nthe path to a GeoJSON resource (`GeoJSON_sample.kml` in this\nexample). Then, create a `GMUGeometryRenderer`, passing the\n`GMUKMLParser` instance. Finally, call\n`GMUGeometryRenderer.render()`. The following code example shows\nrendering GeoJSON data on a map: \n\nSwift \n\n```swift\nimport GoogleMapsUtils\n\nclass GeoJSON {\n private var mapView: GMSMapView!\n\n func renderGeoJSON() {\n guard let path = Bundle.main.path(forResource: \"GeoJSON_sample\", ofType: \"json\") else {\n return\n }\n\n let url = URL(fileURLWithPath: path)\n\n let geoJsonParser = GMUGeoJSONParser(url: url)\n geoJsonParser.parse()\n\n let renderer = GMUGeometryRenderer(map: mapView, geometries: geoJsonParser.features)\n renderer.render()\n }\n}\n \n```\n\nObjective-C \n\n```objective-c\n@import GoogleMapsUtils;\n\n@implementation GeoJSON {\n GMSMapView *_mapView;\n}\n\n- (void)renderGeoJSON {\n NSString *path = [[NSBundle mainBundle] pathForResource:@\"GeoJSON_sample\" ofType:@\"json\"];\n NSURL *url = [NSURL fileURLWithPath:path];\n GMUGeoJSONParser *parser = [[GMUGeoJSONParser alloc] initWithURL:url];\n [parser parse];\n GMUGeometryRenderer *renderer = [[GMUGeometryRenderer alloc] initWithMap:_mapView\n geometries:parser.features];\n [renderer render];\n}\n\n@end\n \n```"]]
