| Abstract: | The concepts and implementation principle of Region, Level of Detail (LOD) and NetworkLink in Keyhole Markup Language (KML) are presented. The method for rapidly loading large image files into Google Earth by using the KML super-overlay files created through KML tags including , and are described in detail. The batch creating of KML super-overlay files based on remote sensing image data is implemented by using VC . The practicality of this technique is verified in a project. |
