User can use satellite image, topographical maps, or other geographical image data that is available on internet or from other sources can be used as image overlays.

Image overlays-Image overlays can be shown over the surface of the earth.

Photos from your Phone, Computer or the Internet can be placed in a geographic location and other users can navigate to this location.

Photos- User can add their photos to Google Earth that they have taken on their Tour.Imagery:User can also import imagery into Google Earth Application, there are two ways to import imagery into Google Earth listed below: These Routes can be imported into Google Earth as paths. Routes-these are the points that the GPS device uses to create the routing, such as when the user searches in the device to “go to” a recorded point from another recorded point.Waypoints-points entered manually by the user while using the GPS Devices and these points typically marked with a name, such as “Home” or “Work.”.These Tracks can be imported into Google Earth as paths. Tracks (or trackpoints)-GPS devices automatically recorded points periodically along a recorded route.While importing GPS data into Google Earth, it gets categorized into three possible folders: GPS data:Google Earth supports most of the GPS devices. In addition to visualize spatial data as KML files, Google Earth allows users to import different types of data, listed below are the details: Other Types of Data That Are Compatible with Google Earth

It can be read and recognized by a number of free and popular geo-based program or application.

It is a portable file that can contain all information such as features, imagery, symbology, descriptions, attributes, and other related content.

KML is an excellent file format to Visualize Spatial Data and content with a wide audience because: A formal coordinate reference system is defined in the OGC KML 2.2 Specification. If altitude is not mentioned then the default value 0 is assumed. The altitude is measured in meters from the WGS84 EGM96 Geoid vertical datum. The longitude and latitude components are as defined by the World Geodetic System of 1984 (WGS84). KML uses 3D geographic coordinate’s reference system i.e.

KML has a larger file space and longer data transfer compared to KMZ file extension.

KML is the file extension for an unzipped file, while KMZ is the zipped version of a KML file which stores the content in a single unit.

“KML” stands for “Keyhole Markup Language,” which is default file extension for Google Earth application while “KMZ” stands for “Keyhole Markup Language Zipped.”.
