KML Feature ArcGIS KML Layer Functionality
  • Placemarks are the primary means of marking a location on the earth.
  • They have an associated label, icon, location (including an elevation), and camera position.
  • You can open (identify) and fly to placemarks.
  • ArcGIS fully supports placemarks.
  • Descriptions for placemarks and other KML items in the Google Earth 3D view as a balloon connected to the item location.
  • In ArcGIS, item descriptions are shown in the Identify dialog rather than as balloons in the 3D view.
  • KML supports drawing objects on the earth using 2D and 3D geometry.
  • This includes points, lines, polygons, and multi-geometry.
  • These can be extruded to fit the terrain surface and have associated styling data.
  • ArcGIS fully supports KML geometry.
Ground Overlays
  • Ground overlays are images that are fixed to the planet surface.
  • ArcGIS fully supports ground overlays.
Screen Overlays
  • A screen overlay is an image independent of the camera position and is fixed to the screen.
  • Screen overlays are not supported in ArcGIS.
  • KML styles define the appearance of geometry, icons, and labels in the viewer.
  • This typically includes color, size, and opacity of the feature.
  • Styles can be embedded in the item or shared using style referencing.
  • ArcGIS supports styles, except for random colors and style maps.
  • KML folders are used to organize placemarks, geometry, screen overlays, and other folders.
  • You can tour placemarks in a folder by flying to each in turn.
  • ArcGIS fully supports folders.
Network Links
  • Network links allow KML content to be fetched dynamically from a KML server.
  • Network links can be defined with automatic refresh properties, allowing the content to be fetched at specific time intervals or whenever the view extent is changed.
  • While automatic refresh of network links (usually by a timer) is not supported by ArcGIS, you can manually refresh the KML layer at any time in order to get the latest content.
Browser Integration
  • KML content can be delivered to the browser using hyperlinks on web pages shown in Google Earth or standard web browsers.
  • ArcGIS supports browser integration.
Interactive editing of KML content
  • Google Earth has functionality for creating and editing KML content through interactive placement of KML elements on to the surface of the globe.
  • ArcGIS does not support functions to interactively create or edit KML content.
Other unsupported KML features The following KML 2.0 functionality is not currently implemented in ArcGIS:
  • Schemas: used for storing information in a table-like format
Other unsupported Google Earth features The following Google Earth functionality is not currently implemented in ArcGIS:
  • Size of / Primary / Secondary Fonts: used with KML labels
  • KML Tour configuration: ability to set the navigation delay at each node
  • Interactive placement of images: ArcGIS already has georeferencing abilities that go beyond move, rotate and scale
