Yes, Tracks4Africa is proud to announce that our maps have now been included as a Featured Layer in Google Earth. This is both an honour and a priviledge for T4A as well as a huge achievement by all our Data Members who over the years have submitted quality data to T4A.
Installing Google Earth
If you already have Google Earth installed on your computer then ignore this section.
To install Google Earth go to the GE web site.
Check out the minimum hardware configuration requirements before you download and install the program. Also note that a broadband internet connection is advisable.
How to view Tracks4Africa on Google Earth
If you are unable to view T4A on Google Earth you may need to upgrade Google Earth to the latest version.
In layers, choose:
More
Tracks4Africa
Switch on "Terrain"
Google Earth tilt and turn to view things in 3D
Using the Google Earth control panel you can adjust height and tilt to get a 3D view.
Using Placemarks on Google Earth
You can save your establishment as a placemark by yourself in Google Earth:
The ‘Places’ panel in Google Earth holds places that you may want to save.
When you create content in Google Earth such as a Placemark, this content resides on your computer, unpublished until you decide to share this content with others. So if you mark the location of your home, no one can see this placemark until you explicitly share it with others.
Google does not collect or view unpublished content on your computer.
Placemarks are not searchable in Google, Google Earth or Google Maps.
Placemarks can be placed inaccurately on the map.
You can share a Placemark with the Google Earth Community (see below).
You can share a Placemark with friends via a KML file.
For more information, consult the Online Google Earth Tutorial
Explanation of Google Earth layers
Google definition of layers:
Typical Layers include: POI’s, Maps, Roads, Terrains, Building Data.
You can display or hide these layers when viewing Google Earth.
Layers content is created by Google or its content partners (e.g. Tracks4Africa). Google publishes the content you see in the Layers panel.
Information which appears in the Places panel, however, can be created by anyone using Google Earth or KML.
More Layer:
This layer is an optional layer to be viewed by the user, which can be switched on and off in the Google Layers. This is typically supplied by a Google content partner like Tracks4Africa.
The data displayed on this layer is not searchable in Google, Google Earth or Google Maps.
Standard Layer:
Content on this layer becomes part of a wider Google Network.
If you have an LEC partnership with Google, and your data appears on the Standard Layer, your data will then also appear on Google Maps and be directly searchable in Google, Google Earth and Google Maps. Tracks4Africa is finalizing this partnership with Google.
Detailed information on Google Earth layers can be obtained from the Google Earth User Guide
Providing T4A with GPS coordinates / making a Placemark
GPS coordinates:
The coordinate format preferred is hddd.ddddd (datum WGS 84). We prefer the saved waypoint to be emailed to us.
If a GPS is not available, the coordinates can be obtained from Google Earth by creating a placemark which can then be emailed to us. Refer below for ‘Steps on how to create a Google Earth Placemark’.
Steps on how to create a Google Earth Placemark:
Detailed information on creating a Google Earth Placemark can be obtained from the Google Earth User Guide
To make this Placemark accurate, ensure that the Eye Altitude is set below 320m (i.e. the eye altitude appears in the bottom right hand Google Earth screen, this altitude changes as you zoom in and out of Google Earth).
To email this Placemark to T4A, follow these steps:
Under "Places" on Google Earth, right-click on your Placemark.
Click on “Email".
Choose your email program.
Google Earth will automatically create a “.kmz” file which will be attached in your email, with the Placemark name.
