KML | Maps SDK for iOS

This page shows you how to render geographic data in the KML format, using GMUKMLParser in conjunction with GMUGeometryRenderer. KML is a popular format for rendering geographic data such as points, lines, and polygons.

The following screenshot shows some example KML data rendered on a map:

GMUKMLParser is part of the Maps SDK for iOS Utility Library. If you haven't yet set up the library, follow the setup guide before reading the rest of this page.

For the full code sample, see the sample apps on GitHub.

To render KML data on a map, create a GMUKMLParser with the path to a KML resource (KML_Sample.kml in this example). Then, create a GMUGeometryRenderer passing the GMUKMLParser instance. Finally, call GMUGeometryRenderer.render(). The following code example shows rendering KML data on a map:

import GoogleMapsUtils

class KML: NSObject {
  private var mapView: GMSMapView!

  func renderKml() {
    guard let path = Bundle.main.path(forResource: "KML_Sample", ofType: "kml") else {
      print("Invalid path")
      return
    }

    let url = URL(fileURLWithPath: path)

    let kmlParser = GMUKMLParser(url: url)
    kmlParser.parse()

    let renderer = GMUGeometryRenderer(
      map: mapView,
      geometries: kmlParser.placemarks,
      styles: kmlParser.styles
    )

    renderer.render()
  }
}
      

@import GoogleMapsUtils;

@implementation KML {
  GMSMapView *_mapView;
}

- (void)renderKml {
  NSString *path = [[NSBundle mainBundle] pathForResource:@"KML_Sample" ofType:@"kml"];
  NSURL *url = [NSURL fileURLWithPath:path];
  GMUKMLParser *parser = [[GMUKMLParser alloc] initWithURL:url];
  [parser parse];
  GMUGeometryRenderer *renderer = [[GMUGeometryRenderer alloc] initWithMap:_mapView
                                                                geometries:parser.placemarks
                                                                    styles:parser.styles];
  [renderer render];
}

@end
